[sdiy] DIY PCBs

[harry]

yeah... My ex-company used to etch with Ammonium Persulfate..... know what
they toss in to stabilize the etchant... a little Mercuric Chloride.

They had to have about 10 trucks of dirt removed when they expanded the
building... that's where the drum storage was...

They also have to run fans 24 / 360 in the new building... to get whatever might
clear the vapor barrier...

wanna guess the cancer rate at that place ???

sorry I'm with Rick... don't etch at home
