I use basically the same, but add one part of acetone to 4 parts alcohol to get the stubborn stuff off.

Pour some in a clean plastic pan or bin (got one the right size for S-100 boards from the dollar store). Fill the bin to cover the board 1/2" deep. Let soak for 5 minutes, use a chemical brush to scrub the board, dip again for final rinse. Pull out, let drip dry, use hair dryer or heat gun (keeping a bigger distance or shorter timer). Pour the alcohol back into the bottle for the next board, you can do 20-40 boards with a 1L bottle, you know it's time to discard when the alcohol turns yellowish.

I'm getting ready to build the 8080A CPU board, so there's going to be allot of solder points. I use Kester 24-6040-0027 21awg solder, but was wondering if there was a better solder in regards to flux clean up. In the past, I have used Acetone, carb cleaner, brake kleen and Blue Shower to clean PCB boards. The 'cleaner' I use varies based on how the solder mask reacts with the 'cleaner' Some chemicals make the solder mask or joints look white. Most of the time I use q-tips and Acetone, but I'm looking for a bulk clean. I want the board to look nice when done. -- You received this message because you are subscribed to the Google Groups "N8VEM-S100" group.
