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

We used to use it all the time in high school. The Graphics Arts lab
was right next to the Electronics lab. The GA guys would whip up a
silk screen and frame it for us. We'd set it in a jig over the pcb,
press it down tight, and squeegee some ink over it. Set it to dry
(under a heat lamp to dry it faster) and etch.

Worked really well with professional looking results. I'm not sure of
the ink we used though (20 years ago now). It was thick and gooey and
blue.
