For a lot of reasons, home etching of PCBs is somewhat of a dying art. The main reason is the rise of quick-turn PCB fabrication services, of course; when you can send your Gerbers off and receive ...

Is plain old FR-4 (also known as “Glass Epoxy”) PCB material suitable for use in RF designs[1]? This question comes up time and again. Many say no, fewer say yes – who's right? As I have published ...

A printed circuit board turns separate parts into a stable system that powers up, talks to peripherals, and survives real world stress. The printed circuit board distributes power, guides signals with ...

A printed circuit board (PCB) mechanically supports and electrically connects electronic components using conductive tracks, pads and other features etched from copper sheets laminated onto a ...

Breadboards are great, but as the world moves more and more to having SMD as a standard, prototyping straight PCBs is becoming more common. If you’re mailing off to China for your PCBs, it’s ...

Back in 2010, Bob Pease sent me a couple pictures of some prototype printed circuit boards (PCBs) he had made in the early 1960s. Pease got to be a great analog engineer because he would hack away at ...
