[Arvid] is using the traditional method of etching away copper, just some ferric chloride and a bit of time. How he’s masking the copper that shouldn’t be etched away is a unique process we ...

[Sebastian] probably didn’t think he was wading into controversial waters when he posted on his experimental method for etching PCBs (in German). It’s not like etching with hydrochloric acid ...

Researchers find a faster way to etch deep holes for 3D NAND Plasma-based cryo-etching technique doubles etch speed, ...

Shadow masks! We're making micro stencils to use in my sputter coater, and talking about how to fabricate them quickly and easily on a fiber laser. Then some examples to see how it works and what kind ...
