Archive of the former Yahoo!Groups mailing list: Homebrew PCBs

What kind of information do you specifically need?

I bought AQ-3000 photoresist, soldermask, and ink legend from the original manufacturer (before Genesis distribution or commercial arrangement).

They are professional products for industrial PCB making. Nothing to do with that silly products for coating woods and other materials, or the hobby Positiv stuff. I also have all of the datasheets and MSDS for the three products. Very clear their instructions, but must be followed whithout change a bit of them. And for soldermaks and ink legend, you must have an air-forced oven, or the PCB surface does not conform to the quality stated.

It is a great advantage to have those products sold for that low price ($68 kilo), when other manufacturers/distributors only sell for minimum $1,000/month.

And yes, you are right, this is the only way (using inustrial PCB-making products) to make decent PCBs at home.
