My Favorite Solder Joint
Posted by: jimjimx on 2017-03-12 11:44:53 HDD power connector from a SE/30 analog board….. Add flux, heat, solder, done…. Yes…. I did the whole board as well…. I know the guy that I got this from, and I know he flew it to LA & back, and home to England & back, a few times.. He never had problems with it, back in the early ’90s. Time has worked into it!! !

Posted by: jimjimx on 2017-03-12 13:06:02 I like that it looks like a exploding volcano.. That was visible without the camera.... C'mon.. WTF Factor... Yeah, I did EVERY point on that board, at 80w.
Posted by: ScutBoy on 2017-03-13 05:15:39 Could the mechanical stress of removing/re-attaching the connector on the other side contributed to this?
Posted by: jimjimx on 2017-03-13 09:13:33 Could the mechanical stress of removing/re-attaching the connector on the other side contributed to this? As far as I know, the HD was only removed once to archive it, and the power connector wasn't pulled off the analog board. If anything, I think it was the vibrations from multiple flights around the world. I got this from the original owner, and know he flew with it a lot in the early 90's.

So true - I got many cheap/free Macs back in the day because they "didn't work". I did my best to give them back after this quick fix, but I ended up keeping a lot of them 🙂
