There may be nothing new under the sun when it comes to etching PCBs with UV light, but [Heliosoph] has brought finer control to a used face tanner he bought that now exposes his boards in ~50 seconds ...

These days, it’s easy to get high-quality custom PCBs made and shipped to your door for under $50. It’s something that was unfathomable only a decade ago, but now it’s commonplace. However, it doesn’t ...

In this technique, fluorine-based plasma chemistry is used for silicon etching, which is combined with a fluorocarbon plasma process to offer sidewall passivation and enhanced selectivity to masking ...

The method of printing PCBs has not changed for decades. In the early days of imaging circuit boards a substrate (copper laminate) was screen printed with a liquid etch resist; this was then oven ...

What is Atomic Layer Etching? Atomic layer etching (ALE) is a highly controlled and selective etching technique that removes material layer by layer at the atomic scale. It is a cyclic process that ...

The copper layers of a printed circuit board are the central focus of any circuit design, the other layers only support or protect the circuit, or simplify the assembly process. For starting PCB ...
