In a recent video [QWZ Labs] demonstrates an interesting technique to use 3D printing to make creating custom PCBs rather straightforward even if all you have is a 3D printer and a roll of copper tape ...

This project, sent in by [Henk], goes through a few different ways to make a solder stencil using a vinyl cutter, a CO2 laser, and a fiber laser. The project starts with identifying a method to ...

What methods can be applied to verify PCB functionality and safety? Which are suitable for mass production and for prototypes? What parameters are checked in each test? How to check a PCB without ...

Effective printed-circuit-board cleaning requires special fluids, tools, and methods. Here are some of the most common to use and to avoid. How to effectively clean and dry printed circuit boards at ...

Building electronics in unconventional form factors with high packaging density is possible thanks to three-dimensional circuit designs using flex and rigid-flex printed circuit boards (PCBs).
