Arsenijs over at Hackaday.io explains how to panelize PCBs using GerberPanelizer on Windows. He writes: This tutorial was done on Windows. Authors claim it could also be used on Linux by using Mono, but I haven’t tried and don’t understand a lot about Mono to see what could be...

This video shows how to drag solder SMD parts with a high density package (in this video a Xilinx XC9572XL with VQFP 64 pin package is used). Drag soldering SMD parts with a flux pen -...

Photons became a hot research topic due to their important role in holding data across long distances. Starting from the fact that photons are insensitive to magnetic fields which concludes to their disability to process data, a group of researchers from the ETH (Eidgenössische...

In the past, I’ve  always seen small circuits of copper with no silk screen or solder mask on top of it and as a PCB designer I have always the question in my mind: What is it for? — I’ve never needed them before! As I can find them in Arduino’s PCBs as well, I decided to open...
