Socketing a replacement spider chip
Steps
- Desolder the failed spider.
- Solder single-row machine-pin SIP sockets into the board.
- Press a second layer of SIP strips onto the spider legs.
- Plug the spider, with its extra strips, into the board sockets; the wide legs then wear the loose strips, not the soldered ones, and alignment is easier.
