Subject: [Homebrew_PCBs] Liquid Tin





Hi,
has anyone ever heard of this "Liquid Tin" by m.g. chemicals ?
this material is supposed to plate the PCB after the etch process, and
passivate the copper.
I never seen this stuff sold anywhere, and I can't get it since I live in
Israel.

first, a link to see it with your own eyes:

look at around 3:30 minutes...

second, does anyone know how to home-brew this material ? Is it dangerous to
use ?

third, does any of you use any other process to passivate the copper after
etching ?

Thanks in advance,
Liquias.
