What is the stuff, anyway?
Where do I buy it?
How would I apply it? Silkscreen?
What do you guys do at Sparkfun? I know you guys put solder masks on the boards you make. Someone wanna let me in on this secret? I'd greatly appreciate it.
Where electronics enthusiasts find answers.

the outside of PCBs to assist in wave soldering. It also
provides environmental protection for the PCB metal,
and improves the readability of silk screen legends.

1. I like doing things myself whenever I can.
2. Microchip has zero PIC18's in DIP packages in stock right now. As it seems to be the trend for most everyone to use SMD these days, I'd like to break away from my dependency on DIPs.

"Chip Gracey designed the Propeller chip completely from the ground up, a feat rarely attempted in a world where most products are based on some excisting prior art, reference design, or chipset."-Make Magazine, Volume 10, Pg. 81, under the header 'Silicon from Scratch'.
"What I liked about what I was doing, was doing it. What was making me happy was the learning and the creativity."This individual not only packaged, tested, and marked his own ICs, but also, by his effort and persistence, the development of his own original ideas into a real, usable, successful microcontroller completely unique from all others, became real. According to you, this I suppose should not have been possible. Apparently, the concepts of entrepreneurial spirit and engenuity are lost on you.
