Parasitics are a part of dealing with electronics: as much as engineers, designers, and manufacturers wish it were possible to work with ideal components, the real world has other plans. Mitigating these parasitic effects is the approach, and there’s a considerable effort at all stages of device DFM dedicated to tracking and compensating for parasitics…
Capacitors are ubiquitous throughout a design for many purposes. From charge storing, signal smoothing, filter applications, and more, these components are often the most populated element on a board. The capacitance and voltage rating (to handle the expected voltage and any spikes) are the primary factors when selecting capacitors. However, a lesser heralded metric can…
Most electronic systems default to copper wire as the transmission medium, and for good reason: it’s highly conductive, readily machinable, and cost-effective. While copper’s applications are nearly universal, its performance can suffer at microwave frequencies and speeds well into the GHz range, where the skin effect causes current to concentrate towards the surface of the…
Designing a PCB starts with the circuit, but the days when the substrate material is an afterthought are long gone. Performance rests on the design’s mechanical, electrical, and thermal considerations, and substrates lacking one or more of these areas are likely to exhibit poor quality and reliability over the device’s service life. FR4 is an…

Trail construction, like roads or other similar pathing, has to contour to the features of the ground beneath it. These trails are usually built to minimize the impact of human activity, meaning the lay of the land takes precedence over ease of use (to a point). Trail designers avoid extended steep climbs, but sometimes it’s unavoidable. When there is the option, most trails will incorporate switchbacks, a longer but less taxing ascent than a direct route over the surface.
As high-density interconnect boards continue to proliferate to meet modern devices’ dual high-performance and functionality requirements, board real estate is becoming more precious. Couple this development with a general tendency for consumer electronics toward portability, and designers must face the all-too-common problem of doing more with less. Historically, one of the more intractable board features…
While most PCB drilling is for vias and through-hole components, some drilling does not encompass electrical connectivity. The board’s placement within the enclosure requires mechanical drilling for fasteners, and some large components, like connectors, may utilize support pins for additional vibration dampening. While simple features overall, PCB mounting hole sizes require a basic understanding of…
The increasing prevalence of electronics in automobiles is welcome to consumers for many reasons: improved features increase safety measures or add new functionality that would otherwise be unachievable.

Medical device contract manufacturing is becoming more commonplace as market forces dictate shorter production cycles without sacrificing quality.
PCB ground planes are usually one or more metal layers within the layer stackup of the circuit board, or in some cases, areas of metal on the external board layers. These layers are referred to by several names, including area fills, copper pours, and negative planes in addition to the standard “ground plane.” Not only do they supply the zero-reference voltage for the circuit board, but they also provide signal return paths for most of the circuitry in the design. That’s just the beginning, though, as there’s a lot more to understanding ground planes in PCB design yet to come.

As signal speeds continue to get faster and faster in circuit boards, designers must do more to ensure the best signal integrity in their layouts. One of those areas that require diligence in design is controlled impedance traces. High-speed transmission lines must have a carefully created trace structure to guide their path without differences in impedance that can distort the signal. Not only does this affect how the trace is routed, but also how the board layer structure is set up. Here is a brief look at impedance control in PCB design and how you can successfully set up your board for routing controlled impedance lines.

A test coupon saves fabricators money, but you won’t find this coupon in a newspaper.
Building a flex circuit prototype can check design feasibility and enclosure compatibility. This piece will discuss some major differences between flex and rigid DFM.
ESD Testing ensures device compliance and safe handling during charge buildup. This piece will discuss the value of ESD testing in terms of quality, reliability, and safety.
When you build a piece of medical equipment, traceability is critical—particularly when building a printed circuit board, as there several individual components and materials that go into the manufacturing of a PCB.
Inadequate inspection techniques leaving you cross? Learn how PCB cross-section analysis provides the most accurate view of manufacturing processes.
Electromagnetic interference (EMI) and electromagnetic compatibility (EMC) are two sides of the same coin: circuit designers don’t want systems to influence other circuits or receive interference from them unintentionally. EMI prevention has become more troublesome within the last few decades for numerous reasons, including gains in switch performance and denser assemblies. Faster speeds and expanding…
Here are some signal integrity testing concerns PCB designers should be aware of to ensure your PCB works how you intended.
From fabrication to assembly, there are a lot of things that can happen to your circuit board. Your contract manufacturer should have the systems and procedures in place to prevent problems and ensure the best quality assembly for your design.
As PCB layout technology has evolved, the manufacturing of circuit boards has changed as well. Fortunately, there is yet another leap forward in the industry that has proven to be a great help: the selective soldering process.
Safety features are often overlooked when a well-designed system operates smoothly within acceptable ratings, as their need may never arise. However, it is crucial not to underestimate the importance of safety until a critical situation demands its utilization. Just like seatbelts and airbags in cars or bike helmets, safety features play a vital role in…
PCB manufacturing defects slow design schedules and cost time and money to rectify. Sidestep some common and not-so-common issues with DFM best practices.
PCB laser drilling is used to drastically reduce the size of interconnections between layers and facilitates HDI design with these microvia structures.
What electronics manufacturers need now is help with component sourcing and a new perspective and approach on how to stay clear of all of the supply chain wreckage. Fortunately, there are some effective methods that OEMs can use to avoid supply chain problems and keep their production on track. Here we’ll examine some of the supply chain problems facing manufacturers and an electronics supply chain strategy that can help.
Are manufacturability issues keeping your design in check? A PCB DFM checklist can set all stages of product development up for success.
Historically, the design and manufacture of PCBs were seen as secondary to the circuit design, but increasing digital speeds and complexity have elevated the need for board quality.
“It’s what’s on the inside that counts” is a message many of us are taught at a young age, and it is an important one. Why? Often, the inner workings of something (be that a person or object) is more important than anything external.
Working in the yard can be satisfying, but renovations can quickly become overwhelming. Last spring, I started renovating a small corner of my yard but expanding the renovation to the entire yard was unfeasible for one person
Most people are familiar with Benjamin Franklin’s famous kite experiment, but most may not know his early forays into electricity extended far beyond that. Franklin worked with early capacitor technology. He correctly hypothesized that electricity was not composed of two separate “electrical fluids” but a single “fluid” of a positive and a negative element.
Balance is a tricky thing. Athletes historically have been concerned with building their strength and endurance. However, balance has taken a backseat until recently, with activities like yoga becoming more popular. Balance helps prevent injury by promoting proper posture during other activities, helping strengthen lesser-utilized muscle groups, and curbing injury.
Going to the doctor can be an anxiety-inducing experience for many because it unlocks fears of the unknown. In extreme cases, this anxiety manifests as iatrophobia or fear of seeking medical care.
Sometimes, it’s difficult to fully appreciate how small electronic components have become. Even those with familiarity working with breadboards or hand-soldered electronics projects may have no idea that the packaging technology on display there may be several decades out-of-date from modern components.
You need to know what may be changing with your PCB’s components far enough in advance so that those changes can be effectively managed without hurting the production of your PCBAs. And in cases in which a component is no longer available, you need the engineering services of your CM for end-of-life (EOL) components to plan for component obsolescence.
Shoe shopping for backpacking trips is a semi-illuminating experience. While there was much discussion of the pros and cons of different features like style, ankle support, etc., a common pain point was the discrepancy in half sizes.
Here’s a closer look at the ISO 13485 certification key elements and how having that certification in place by your PCBA contract manufacturer will benefit you.
When faced with a daunting project, the recommendation I’ve received all my life from educators and professionals is “break it into smaller pieces.” From an approachability standpoint, this is excellent advice.
I love the solitude of being out in the mountains. When you’re miles away from civilization and thousands of feet above sea level, my mind stops racing, and I can simply admire the beauty of my surroundings. Unfortunately, this solitude comes at a price. Some of the most desirable backpacking spots in the U.S. severely restrict reservations to maintain this sense of seclusion.
Following checklists for flying is critical, as not doing so can result in disaster. The same is true while designing a printed circuit board. If you don’t already have one, here are some ideas on how to create a simple but effective PCB layout checklist for yourself.
I wouldn’t describe myself as athletic, but I do plenty to keep myself in shape between hiking, running, and cycling. Overconfident in my general fitness, I recently accepted an invitation to a friend’s yoga class, where I subsequently suffered in a calming silence for 90 minutes. It’s impressive how flexible the human body is, or conversely, how intractable it can seem when it’s not been properly trained.
The car I drove for most of my 20s had several peculiarities that only revealed themselves once it hit the freeway. I heard a strange high-pitched whistling sound that could never be replicated in the shop and noticed a window that would slowly begin falling at some elevated vibrational frequency.
I love cooking for large gatherings. Cooking for friends and loved ones is among the most meaningful expressions of warmth and gratitude. A few years back, at Thanksgiving, we were tasked with cooking dishes that adhered to multiple diets and allergies.
From its humble inception among computer hobbyists to burgeoning arcades and home console libraries in the 70s and 80s (pre- and post-market crash), much of the legal landscape of the video game industry was poorly equipped initially to grapple with subjects like emulation and third-party software.
I naturally gravitate towards endurance exercise rather than high-intensity as I grow older. There’s something about keeping a steady pace for an extended period that I now find much more physically rewarding and mentally stimulating. Whether riding my bike or taking a backcountry trip, incorporating this constant and measured movement has become second nature.
I am fond of the boxy car bodies of the 80s and 90s. Call it nostalgia, but seeing one of those beauties rolling down the highway with its lack of aerodynamics puts a smile on my face. Beyond the aesthetic value, I’m terrible at working on cars, and the less complicated it is under the hood, the better I can troubleshoot any issues
I’ve never been much of an artist. Whether it’s a lack of creativity or poor fine motor skills, I’ve only rarely been able to produce drawings and paintings I felt satisfied with by the time the pieces were complete. One of the things that greatly impressed me when taking a few directed drawing classes was how the illustrator was able to explain how they were visualizing features that they were drawing: a “C” for an ear or a “?” rotated 180° for a nose.
There are countless examples throughout human history of how using the wrong tool for the job can make the job harder. A perfect example: most people have tried to use a slotted screwdriver in a Phillips head (or vice versa) at least once. However, this universal law extends far beyond hand tools; it can also be applied to building printed circuit boards.

I was tasked with putting together a bookshelf a few months ago. I thought it would be simple enough until I realized the documentation provided was for a completely different piece of furniture! Thankfully, most pieces were unique enough that I could slowly work through trial and error by referencing the images on the box.
During the testing stage, if you discover issues like unwanted signals interfering with the
device’s operation, components consuming more power, or overheating, there is likely some error in design. The late-stage discovery of these errors can mean an irreplaceable impact on manufacturing cost, product quality, and device performance.
As board materials pass through production, how does a manufacturer know whether a board is performing suitably and as expected? Depending on the techniques, materials, equipment, labor, and components, PCB manufacturing can incur high costs per panel. It is in a shop’s best interest to sniff out defects and failures early.
I used to check my physics equations by hand in college, despite powerful solvers available to me with a few clicks and keystrokes. It may have been an appreciation for the process work or plain stubbornness. Either way, whenever my solution didn’t match the author’s, I needed to know that my errors weren’t conceptual or algebraic.
At any given moment, our brains can unconsciously process complex data streams through different senses. To avoid maxing out our bandwidth, most of what we perceive passes through without notice – think of how distracted we would be if every sensation were registered.
Form factor is a driving force in electronics adoption, with the classic example being the invention of the microprocessor. Before the microprocessor, computers took up entire rooms due to the space requirements of vacuum tube technology.
Visual stimuli dominate most people’s modes of information acquisition, allowing the absorption and filtration of pertinent data from our environment in a highly rapid manner. So much of our communication is tied up with our sight that we have developed languages and methods to transfer nonverbal ideas.
Unlike consumer electronics which are highly fungible due to rapid advancements in technology and market forces, a PCB installation may be intended to last for several years, or even a decade depending on its role.
Unlike consumer electronics which are highly fungible due to rapid advancements in technology and market forces, a PCB installation may be intended to last for several years, or even a decade depending on its role. The stress/strain on any cables in the fixture can imperil long-term reliability and, ultimately, baseline functionality if not properly accounted for.
Modern society is saturated with printed circuit boards. Despite this, it can be difficult to explain such a technical field to those looking to gain entry or even just knowledge.
Most fictional sci-fi utopias (and sometimes, the set up to some dystopias) are attributed to a technological breakthrough whereby all work is handled by machines. Freed from responsibility, humanity can live a life of leisure and exploration, content to let their material needs be met by a continuously operating AI workforce.
It’s fun to look at the ads of bygone eras and reminisce (or maybe just laugh) before the centralization of the internet.

It’s amazing to consider how far certain technologies have developed within a couple of decades. Though I only experienced it partially as a child, I still vividly recall the days of dial-up internet.
When was your first warning to be careful around high-power electricity? Was it playing near powerlines in your childhood, or perhaps attempting to insert something besides insulated prongs into an outlet?
What was your first experience having an electronic device spark, smoke, or otherwise indicate it was unsafe to continue using? As a child, I distinctly remember the time my brother plugged in a lamp that had its insulation wrap chewed by some mystery creature.
Have you ever finished a movie, novel, or another piece of rhetoric and immediately rushed online to see if you missed any deeper meaning? We can gain a greater appreciation for stories when we can put them in context or gain insight into themes, symbols, or other narrative devices.
At some point, we’ve all suffered anxiety from a dead phone battery when we’re out and about. Though its severity may affect some worse than others, the truth is for most people, it’s become our primary method of contact.

Reliability is paramount to how electronic products and brands are perceived. For most people, electronics troubleshooting goes as far as swapping batteries or disconnecting/reconnecting power.
Planning a surprise party involves a lot of moving parts. Generally, one person heads up the invitations to avoid someone unintentionally spoiling the event. Logistics are important because anyone arriving too close to the celebrant will ruin the surprise
In chemical reactions that favor a total conversion of products to reactants, reactions proceed until one or more are consumed, based upon stoichiometric ratios. These reactants, known as limiting reagents, represent the upper limit of efficiency.
Both my physics and engineering college professors expressed a mentality of “do it right or do it twice” to instill course material and problem-solving methods into their student’s heads. They thought anyone in those courses could pass one of their notoriously difficult exams.

Whenever I’m planning how to design a circuit board, I’m reminded of the famous quote by Laozi, “A journey of a thousand miles begins with a single step.” Perhaps I’m being dramatic – layout design is not a thousand-mile journey.
“It’s what’s on the inside that counts.” Most of us have heard this in wildly different contexts than PCB design. Still, it’s true more generally: diving beyond the surface is likely to reveal the most critical features, attributes, or characteristics of many things, both esoteric and universal
When I was a kid, I remember leaving on video game consoles overnight when it was “lights out” because my siblings and I were at a point where we couldn’t save and exit the game. Faced with a loss of progress, we decided it was more beneficial to keep the hardware running and pick up where we left off later.
One of my favorite team-building activities from school was constructing a stable tower from marshmallows and dry pasta under a time limit. This brainstorming exercise challenged teams to construct the tallest structure without external support.
Years ago, I was remapping the functionality of an RC car for a school project. My team and I had to design, shop, build, test, and debug an analog circuit that added cruise control functionality and IR sensing.
Surely many people can relate to a phone charger that only works when the wire is placed in a certain position. Being a bit of a packrat, I have several frayed chargers within the same nightstand that I save for extra parts and replacements.
I tend to be overly cautious when planning my routes on new long-distance backpacking trips. I’ll start with detailed route reviews that pour over elevation maps. These reviews, combined with approximate pack weight, indicate how strenuous each hour of the trip will be and when to plan my breaks. With the wealth of geographical information available, it’s easy to determine how long I can expect to spend on a trail each day.
Like most, I’ve witnessed the loss of local businesses during the fallout of the COVID-19 pandemic. While it’s sad to see restaurants go, my region’s bike shops almost wholly disappeared. I once had multiple stops nearby for repairs, including national chains, all of which have moved or shuttered within the past two years.
I have a habit of reusing and repairing items that many would throw away or abandon in their garages. With a bit of work, there’s a treasure trove of items available to revive for all kinds of hobbies and interests. For me, this also extends to electronics – I’m particularly fond of restoring old NES and computer systems.
One of my favorite pastimes is following the development of game strategies. Especially in the realm of video games, slight tweaks or counterplay to the gameplay results in new discoveries without changing the underlying game. In other words, a finalized version of a release may evolve over time as the same physical product.
Classifications can get messy. When taking my CID course, I was overwhelmed by the amount of knowledge to keep track of in the industry and related disciplines. Most of it was beyond retention for all but the most seasoned veterans. Individual rules or mandates can be difficult to recall. Still, best practices provide an excellent foundation for the motivation behind some tasks, whether reliability, performance, or other essential characteristics.
Technical terminology is a necessary part of any industry. As a topic’s specificity increases, so do the need to quickly and accurately convey information without room for ambiguity. Conversations lacking in this specificity can result in misinterpretations during design and manufacturing, sometimes severe enough to warrant rework or scrapping.
Making a sandwich is a simple enough construction — assemble your bread, meats, cheeses, vegetables, and condiments in such a way that has both structural integrity and flavor. What varies in designing this famously simple meal is not only what you put in, but where, and how much. It’s a common misconception that different areas of the tongue correspond to different flavor sensations.
Packing a cooler is a time-honored tradition for beach trips, camping, and cookouts. I remember the first time I was on cooler duty. Typical of my thought process, I put a bed of ice in the cooler and placed all perishables on top. As you might have guessed, my family was not impressed with my record-breaking cooler pack.
“Measure twice, cut once” is the guiding mantra to prevent irreversible mistakes during any manufacturing process. However, no matter how many eyes check a document or process, some defect or error eventually sneaks through. Luckily, not all errors are equally disruptive, and focused efforts on the primary modes of failure or performance issues can prevent complete malfunction. Establishing and communicating clear design intent also helps prevent ambiguity from sneaking into production, reducing the possibility of issues arising.
Before starting any project, it’s necessary to determine which materials will compose the final product. Whether cooking, painting, or building electronics, it’s crucial to pick suitable materials that express th necessary characteristics of the finished piece.
One of the best lessons I’ve learned in my career in PCB design is realizing when I’ve gone too far. It’s easy to miss the forest for the trees when you’re in the weeds of placement, layout, routing, and other core tasks, but sometimes it’s necessary to take a moment to reflect on your work. Sometimes I’ll find I’ve overlooked some crucial element in the design documents or strayed from the engineer’s intent. In this case, saving the work I think is worthwhile, and undoing the rest with a backup file can seem like an easy fix.
I’m extremely prone to moments of forgetfulness. Whether I’m working at the house or out on backcountry trails, it’s very easy for my head to get lost in the literal or figurative clouds. Regardless if I’ve set my phone (or my keys, or my wallet) somewhere I can’t remember or I’ve wandered past a junction onto trails unknown, I’ve learned to accept and adapt: I’ve mastered the art of retracing my steps.
Several summers ago, I took up jogging to break up the monotony of my current cardio exercises. I love cycling, but jogging offered something more personal: an ability to explore the outdoors leisurely, without any tool or gear beyond clothing. I quickly discovered a favorite route and began to relish the feeling of the sun on my skin and breeze through my hair. Unfortunately, as I continued my daily routine, I failed to account for the intensifying weather of the season and was left with a nasty sunburn.
During the COVID-19 lockdown, I attempted to make pizza several times. It was fascinating how much thought went into the baking process itself. As I consider myself more of an intuitive cook than a baker, the science of yeasted dough was difficult.
When I’m packing for vacations, I tend to overpack. Especially when camping, I like to make sure I have any tool I could need. Unfortunately, I built up my gear by purchasing items that serve one purpose instead of a multi-use functionality. While I have the tools to perform the tasks I need, my bags can get heavy with so many single-use tools. Lately, I’ve learned to lighten my load with multi-use tools.
A competitive PCB software market benefits end-users, but getting started picking software may be daunting. As with most things in the consumer world, users are saturated with choice. While this isn’t necessarily a bad thing, it deters beginners or startup companies looking to prepare their designs for manufacturing. Professional PCB software licenses are not cheap. These design suites are packed with more tools and functions than even the most expert designer will use, along with many features that appeal to a wide range of users.
When it comes to cooking and baking, one often hears the delineation: the former is an art, while the latter is a science. If that’s true, consider me a jazz musician in the kitchen – I work from mental fragments of recipes, adjusting the quantity based on what’s on hand and substituting items with impunity. This strategy allows for significant tinkering with cooking time, spices, and ingredients, allowing me to construct a dish as I see fit and as tastes evolve.
A board has passed through the final assembly process and culminated in a finalized, realized product that is likely months of combined design from engineering through manufacturing. While this stage represents a significant milestone, there is still apprehension about whether the board will pass through quality assurance. In reality, the board has already moved through some critical checkpoints to reach this stage. However, there are still numerous tests before a board is considered ready to ship.
Designing a board may be challenging, but even more so getting a product successfully to market. Competition is fierce in any field, and established companies can commit millions to firms that assuage consumers’ interest in features. In the event of competing releases, perhaps there is no more relevant adage than “the early bird gets the worm”: except for drastic performance or price differences, most customers will flock to what’s available when it’s available.
When packing a bag for a backcountry trip, I juggle numerous essentials necessary to survive, prepare, and avoid overload. It’s impossible to balance a “perfect” solution – overpack and I’m miserable, pack too restrictive, and I’m flirting with life-or-death situations. It turns out that the best method comes from making reasonable trade-offs, such as researching the weather to determine how necessary rain or low-temperature gear might be.
When prepping for a backpacking trip, list-making is the first tool I turn to for organization. By running through and ensuring that every item is present and gear has been checked and functioning as intended, I can relax rather than worry. After all, there’s nothing quite like being 10,000 feet above sea level and several miles from civilization (or even the next closest human) to realize you overlooked something.
No device represents the next big thing better than the self-driving car for consumer technology. It was conceived as an end to the monotony of the work commute and sold as a revolutionary product that is quickly making gains with advances in computer vision. Computer vision is driven by harnessing data from onboard sensors. While devices have become more sophisticated, the core to solving the problem (and many similar issues across a bevy of industries) relies on enhanced communication.
Having a house painted usually involves more work than homeowners expect. Often there is siding to replace, gutters that need maintenance, and other unexpected problems that require attention. You can coordinate the various contractors necessary to do these tasks or do them yourself
It’s hard to imagine now, but seat belts weren’t required in cars at one-time. However, the lap and shoulder-harness seat belt became the industry and cultural standard in most places after many injuries. Now you can’t drive too far down the freeway without seeing a “Click It or Ticket” sign posted alongside the road.
Designing and manufacturing PCBs is so complex that it’s easy to forget what happens to a fully-functioning and regulated board once it leaves the shop. After a hopefully long and uneventful service life, the board will naturally reach the end of its use or become obsolete due to the presence of a revision, upgrade, or entirely new product. The business world refers to this situation as an externality: an unintended consequence of industry.
For longevity and the best performance of the circuit board, it must be handled with the greatest of care. Here, we will look at some potential problems associated with rough treatment and the rules for handling printed circuit boards to avoid these undesirable consequences.
The question on everyone’s mind now is how long these shortages will continue. OEMs want to return to full production of their products, manufacturers want to supply customers’ demand, and end-users want access to the latest products. Here we’ll look at the electronics parts shortage, how it is affecting the printed circuit board industry and some ways that designers can work around these problems.
The implementation of RoHS has greatly reduced the presence of dangerous metals and chemicals that may eventually escape their packaging and be a downstream health concern to local fauna and flora. However, the industry is multitudinous enough in its applications that a RoHS compliant PCB is not always the best solution. In cases where RoHS materials would directly impact human health and safety, it is far more important to support the reliability and operational stability of the device.
Just as the ABCs are the basics of English language skills, other skills also rely on basic principles or ABCs. One of these is circuit board design and layout. Although PCB design encompasses various board types and design technologies, some basic ABCs still apply. Here is a list of the ABCs of PCB design basics that can help engineers avoid problems and create successful designs.
PCB repair functions much in the same way: given a large enough production lot or a long field life, a board will inevitably need maintenance. Rework before field usage is also critical, and some amount during manufacturing is always expected. In either case, technicians should be able to identify some of the common modes of failure for PCBs to more quickly and effectively reduce downtime for boards and return them to operation.
The RoHS requirements restricted the use of certain toxic materials during manufacturing, forcing changes in processes, materials, and components used in building electronics. Although this was a difficult change to incorporate, it has since been accomplished successfully by many PCB contract manufacturers. Here, we’ll look at the RoHS PCB manufacturing requirements in place today and how PCB CMs work with these regulations in producing circuit boards.
Quality management systems (QMS) and other PCB certifications will provide customers and partners with the faith that an operation complies with current industry standards and grants operations the knowledge and training to reduce scrap and rework and save on costs.
High current PCB practices need to be employed to keep a board in operation but functioning in lockstep with its design intent to avoid any issues during prototyping or field use.
For those of us that spend most of our time working on schematics and layouts within the virtual world of CAD tools, soldering gives us a chance to interact with the actual hardware of our designs. However, soldering components on a circuit board must be done correctly to avoid problems that could affect the performance of the board or outright damage it. Here is a basic guide of best practices that engineers should know for through-hole soldering.
Heat is the expected by-product of a normal functioning circuit board. But if heat isn’t carefully planned for during its design, the PCB may have problems during its manufacturing and operational performance. Here we’ll take a look at PCB thermal resistance and conductivity and see how good thermal management is ultimately essential to the success of the circuit board.
PCB thermal conductivity influences all design aspects, beginning with stack-up and material choices and continuing through the layout. External heatsinks can be included in the design further to reduce heat buildup on or within the board.
Here, we’ll look at some of the problems to avoid during soldering and some of the best practice PCB soldering techniques that can help.
When it comes to the best PCB materials, it is of utmost importance to first consider the function of the underpinning physics driving the final product’s function.
Everything from diagnostic equipment to blood analysis systems relies on electronics that must function perfectly every time. This level of reliability requires absolute precision and quality in the design and manufacturing of PCBs for medical devices, which we will examine in greater detail here.
Process work must be done to prepare the boards to be separated mechanically. This work is done through two methods: V-Scoring and tab routing. Both panelization methods find use depending on different design elements of the board. Below, it will be explored in greater detail and comparison-contrast.
EMI/EMC is pervasive throughout the design and taking into consideration the many ways in which it can be accounted for, represents an opportunity for a discerning layout engineer to potentially limit EMI without the need for additional shielding. However, the balancing act of particular layout jobs may require that EMI/EMC is addressed via shielding materials after the finished board is prepared for a final inspection.
The fallout from the COVID-19 pandemic’s disruption of global supply lines has created a backlog that many industries are still mitigating. The best way to sidestep the international manufacturing gridlock is by onshoring supply chains. While a top-to-bottom restructuring of global industries does not happen overnight, there are still multitudes of solutions and benefits for national businesses that can be realized today.
PCB CMs understand both the fabrication and assembly side of manufacturing a circuit board, and they can choose the best PCB fabrication shop to work with to produce a high-quality board. Here’s how.
Flying probes have seen wide adoption over the past three-plus decades, especially in the realm of prototyping and other low-volume production runs. However, the advantages provided by a PCB flying probe test quickly erode when scaling for larger productions. An explanation of the PCB flying probe test, its benefits, drawbacks, and alternatives to the test are offered below.
PCBs also need to be tested, which require test points to be strategically designed into the board along with placing the components and routing the connections. Bare board continuity testing, in-circuit test, and flying probe testing all require the presence of test points on the board to facilitate their processes. Here we will look at the top seven PCB test points layout strategies that designers need to understand to build a fully testable circuit board.
Efforts are underway to reshoring semiconductor manufacturing, but the time it takes to design, build, furnish, and staff a foundry means these efforts will not bear fruit for several years. Stateside printed circuit board manufacturing possesses numerous advantages over traditional global fabrication and assembly chains, and some of the reasons are outlined below.
Thankfully, electronic CAD tools have numerous standard features to create redundancies that minimize errors during all stages of PCB design. These integrated suites help streamline design flow from schematic capture to documentation to fabrication and assembly through many clever and common functions. The following features will form part of the indispensable aid that electronic CAD applications offer designers to ensure designs meet their intended specifications at the outset.
Successfully navigating the semiconductor chip supply chain shortage requires a different set of skills than what PCB design groups have traditionally had to wield. Here are some ideas that your design group may want to consider to work around these supply chain difficulties.
Carelessness in part placement can have a disastrous effect on the final product’s manufacturability, performance, and overall quality. Here we will look at surface mount components of a PCB and some of the more common SMT placement issues.
Building a printed circuit board requires a lot of data and information for your manufacturers. A circuit board is first fabricated, where the layers of dielectric material and metal interconnects are laminated together and then assembled where the components are soldered into place. Finally, the board will be fully tested before being shipped back to the customer who ordered it.
When creating an effective parts placement, many concerns have to be considered, including signal performance, power integrity, accessibility, and manufacturability. And although you may have to make compromises between these different requirements, some rules must be followed, especially when placing surface mount parts. Here are some SMT component placement guidelines that can help.
Where’s your first stop when you enter the store to shop? If you’re anything like me, you’re a bargain hunter, and it’s straight to the clearance rack. Even when grocery bills aren’t soaring, I appreciate the simple surprise of trying a new product I’d otherwise pass over or stocking up on a favorite. This shopping mentality presupposes that the items you pick are more or less equivalent.
As with any manufactured object, circuit boards can also be plagued with unexpected defects. OEMs can trace PCB defects back to many causes, which is why it is so important to detect these problems early on before they become unmanageable. Fortunately, there are many methods available to designers and manufacturers for PCB defect detection, and we will look at some of these methods here.
Designing on paper certainly has a nostalgic charm, and many of us learned circuit design using simple drafting tools. However, circuit board design has become more complex since the good old days of using a drafting board. If you are still using pen and paper, you miss out on some beneficial functionality available in even the most simple schematic drawing software tools. Let’s compare pen and paper schematics with CAD schematic capture systems and see some of these differences.
Have you ever had a meal dining out that you were sure you could make better at home? I don’t consider myself a great cook. Still, there are the rare disappointing occasions at the restaurant when I realize I could’ve just stayed home and cooked something probably healthier and cheaper.
It is crucial to take basic steps to ensure design integrity before converting the schematic to a PCB layout.
PCB layout best practices incorporate a wide set of guidelines, mostly regarding manufacturability, signal integrity, and reliability.
Design teams need to ensure that their library data is up-to-date and ready to avoid costly and time-consuming delays. Let’s look at some good CAD library management practices and ideas to guarantee that your PCB libraries won’t let you down.
Industrial circuit boards are typically used in applications that require high power levels to drive motors or other heavy-duty equipment. Because of these power requirements, the layout rules and constraints are different than what would be used to layout a low-power IoT device. Here we’ll look at some of the differences with this type of circuit board layout technology and what designers need to understand about industrial PCB design rules.
Thankfully, most people do understand the importance of PCBs and their uses, but very few understand the design and manufacturing processes required to build them. To help, we have put together a PCB flow chart that describes the design and assembly processes and how the two interact with each other. For clarity, we have omitted the fabrication process—other than to note the procurement of raw PCB fabs; otherwise, the following should help to simplify the overall process.
This component availability problem can be traced back to several reasons. In some cases, it is due to inadequate planning, while others are due to CAD library management issues that designers need to understand better. Here we will examine these potential problem areas and some good PCB design BOM inventory management practices.
The chip shortage and the global supply chain problems are big news these days, but do you realize how much the chip shortages impact supply chain resiliency?
