This post continues from “How to Design the Perfect PCB – Part 1.” In part one we covered how to finish the pre-layout work like setting goals, visualizing your design, and selecting parts. In this post we focus more on the physical side of PCB design and discuss the caveats that may trip you up.
Before we get started, I think it is worth saying that this is NOT a guide on how to use any specific CAD software. This article is meant to serve as a general guideline on how you can design the best possible PCB regardless of your experience level.
When I set out to design my first PCB I was told “Well, it’s your first PCB so it probably won’t work anyways, but that sounds interesting.” Even though this was discouraging to hear, I didn’t let it stop me and I ended up with a working design. I now want to take my experiences as well as the experiences of others and make it as simple as possible for you to design your own PCB.
