Hi Jim, In my limited experience with solder joint requirements, the "j" hook is required when soldering in accordance with the weapons specification (WS-????), however, I'm not familiar with an IPC req't. The obvious advantage of using a "j" hook is based on additional support of the joint when the joint may experience mechanical stress in the field. Hope this helps...

I believe that creating a good mechanical connection is priority #1 and then solder the joint. But, is it ok to just lay the two wire ends on top of each other and solder the joint and same with the potentiometer, is it ok to lay the discrete wire on the potentiometers lead and then solder the joint. If anyone can give me some pro's and con's to both techniques, I would greatly appreciate it.
