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.

With the number of files associated with a PCB design, it is easy to get confused and lose track of which files are current and what they contain. It is important to develop a naming system that is easy to understand and use, especially with the image files, more commonly known as Gerber data to prevent any confusion. Here are some recommendations for Gerber file names that can help keep your manufacturing data clean and up-to-date.
Meticulous planning has also become essential when designing a new circuit board. Due to the current state of the electronic component supply chain, the confidence we once had in the availability of the necessary parts for our electronics has all but disappeared. Creating a new design today for long-term production requires specific and detailed strategies. Here are some ideas on PCB design BOM planning methods to help you avoid component shortages in your next electronics project.
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.
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.
