Do U17,U15,U10,U6 perhaps have some solder bridges, or
is that just some
flux hanging around?
It's flux, but thanks for the heads-up! I went over everything with
liquid-flux-soaked solder-wick and a stereo microscope ... there were a
ton of solder bridges before. Scrubbing the board in alcohol and then
water gets 99% of the flux off, but turns the remainder white. Now I've
scraped most of it out with a razor blade.
Also, I think I have ninjas. Cooking this board let out an unusually
large cloud of vile rosin smoke, and until I aired the house out, there
were weird thumps and bumps coming from every corner but there was
nothing there when I turned to look.
