Although DIY PCB making has made great strides since the early days of chemical etching, there’s one fly in the ointment: vias. These connect individual layers of the board with a conductive tube, and ...

For the few double-sided PCBs we’ve actually etched at home we simply soldered a piece of wire to either side of a via and clipped off the excess. But if you want to go the extra mile you can’t beat ...

Gold plating is a term that is generally used to describe a thin gold coating on an object. As a matter of fact, gold can be deposited from a solution, by using three similar processes. These include: ...

Abstract: Void-free electroplating of copper in high-aspect ratio via structures is an important capability for achieving high-reliability through silicon vias (TSVs). In this study, the evolution of ...
