Homebrew PCBs

Someone I used to know heated his fecl3 in the microwave before etching . when I worked at an electronics plane we used a single burner electric stove and ammonium persulfate . for me either one worked well . as for hcl , has anyone had corrosion issues on finished boards because there may have been some residue ?

Hi there,

Newbie here.

I use FeCl etchant, poured into a (genuine, high-heat) Pyrex baking dish which I heat on an single burner electric stove. Use a HF (or ExeTech via Mouser) IR pyrometer to measure the acid temperature. It'll fume when its hot, so do this outside.

Cheers
