My question is for all the people who have etched their own circuit boards (BOA, JIP, Fritsl?, Others?).
I would like to know:
1. how many times you have made your own circuit boards.
2. how long does it take. Is it faster than wire-wrap or "free-form" soldering?
3. how many boards have you made in a run?
4. have you ever tried commercial sites? how would you compare vs doing it all yourself?
5. what is the start-up costs?
6. what do you do with the spent chemicals?
