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 ...

A collaborative research team from Nagoya University and Tokyo Electron Miyagi Ltd. has demonstrated that the company's new ...

In dry etching, the trajectory of accelerated ions is non-uniform and non-vertical, due to collisions with gas molecules and other random thermal effects (figure 1). This has an impact on etch results ...

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 ...

While low-cost professional PCB fabrication has largely supplanted making circuit boards at home, there’s still something to be said for being able to go from design to prototype in an afternoon.
