Printed circuit pins repair

Good work. Most of the soldering looks correct, with the solder in smooth volcanoes that flows up on the pins. Wash off the flux well. I use GoJo or Lava soap on a toothbrush. At a past company, they washed new circuit boards in a dishwasher to remove flux, so don't be afraid of water. These repairs are easy, and anyone can do them. You should see how people repair modern circuit boards with tiny traces. Possible, but takes much skill and proper equipment.
