Such badges are easy enough to make with a CNC machine, but if you don’t have access to machine tools you can put chemistry to work for you with these acid-etched brass nameplates. The etching ...

(Image: A*STAR Institute of Materials Research and Engineering) Wet etching can be classified into two main types based on the etching mechanism and the resulting profile: It's worth noting that wet ...

Schematic representation of the atomic layer etching (ALE) process, which is used to precisely shape materials at the nanoscale. At the top, we see two types of ALE: (left) isotropic etching, which ...

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 ...
