I have a board populated with through-hole electronics components that need some careful rework. Your task is to desolder the existing parts, clean the pads so they are free of excess solder, and then solder the new components in their place with neat, shiny joints. The job is limited to standard through-hole work—no surface-mount parts are involved. You can use your preferred iron, pump, braid, or flux as long as you leave the board in good condition: no lifted pads, no scorched traces, and every pin electrically sound. Please allow for a brief video or photo check of the finished joints before we close the project. Once everything looks solid and passes a quick continuity test, we’re done.
