I ask this question for those who have not made the mistake I did: any suggestions on how to best remove the flux residue off of the Peggy 2 board after assembly is complete?
OK, not having bothered to ask the question before acting, I decided that Isopropyl Alcohol followed by a water rinse would probably do the trick. Bad, bad, really dumb idea: yeah it removes the flux, and the shiny finish on the board, leaves a white sticky film (which I assume is the former board finish), and appears to have lightly oxidized the solder joints. Other than that, it was a huge success. Anything I can/should do at this point? The board seems to be working fine, I'm mainly concerned with anything I should be doing to prevent any longer term oxidation issues as well as anything that can be done to improve the appearance (having done this, I can attest that it now looks far worse than if I had just left the residue alone. The good news is that I only did this on the back of the board, the front is still pristine.)
P.S. one minor silkscreen / doc bug: both reference removing JP1 when S3 is installed. Shouldn't that be JP5?
