PCB Capacitor Identification And Selection

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.


PCB for Solar Panels: Up-To-Date Green Tech

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.


Class 1 vs. Class 2 Circuits: Understanding Different Classifications

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.


PCB vs. PWB: Circuit Board Terms Defined

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.


Peeling Back: PCB Layers Explained

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.


The Effect of PCB Impedance on Design

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.
