Final assembled 8800 M/BD as viewed from the top.

Use a soldering iron with a fairly large chisel tip, that can supply plenty of heat.

If a socket is not fully seated, then heat up the soldered pin on the unseated side of the connector, and apply light pressure to seat the socket fully.

If any bridges are found, remove them using solder wick.

Remove solder flux with a good-quality flux remover, such as MG Chemicals Heavy-Duty Flux Remover.
