Here’s two hacks to etch your own boards ... us about [Tom]’s etching process that is like wiping the copper off the board. He used Muratic (Hydrochloric) acid and Hydrogen Peroxide ...

One of the main challenges is the control over the etching process, particularly in terms of the etch rate uniformity, surface roughness, and feature size variability. The development of advanced ...

Luckily, [Rich] has come up with a way that eliminates multiple prints and the acid needed for etching. His process involves using a laser printer (as opposed to an inkjet printer, as is tradition ...

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 relies on self-limiting chemical ...
