recapping

33 videos.

Recapping means replacing the electrolytic capacitors on an old board, usually because they have dried out or leaked. Spilled fluid can eat tracks and pads, so a close look at the board comes before any iron is heated. The surface-mount capacitors on Amiga 600 and 1200 boards are a common case.

For the removal step, the comparison of five ways to take off surface-mount capacitors is sponsored by PCBWay, and its choice of winner is the maker's own judgement. One Amiga 1200 episode pairs a recap with a floppy repair and a ROM swap. A Game Boy that arrived dead is recapped in this DMG video, with reflow and shell work after.

Leaked electrolyte is corrosive. Hot tools at the board can burn you, so ventilate against the fumes and remember that old solder holds lead.
