For a lot of reasons, home etching of PCBs is somewhat of a dying art. The main reason is the rise of quick-turn PCB fabrication services, of course; when you can send your Gerbers off and receive ...

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 ...

An example of directional etching for nanohole arrays of less than 500nm in diameter. (Image: A*STAR Institute of Materials Research and Engineering) Wet etching can be classified into two main types ...

Many hobbyists and hackerspaces have the $500 Chinese 40W lasercutters which most of us know are about as successful at etching metals as a featherduster is at drilling. [Frankie] and [Bryan] have ...

This innovation is the first of its kind in the world and is designed to extend the lifespan of internal components in semiconductor etching equipment while reducing contamination particles during ...
