Notes from an AIM No-Lead Presentation ... Wave Soldering * May require a higher pot temperature than tin/lead: 255-265*C * May require a change in liquid fluxes to compensate for the poor wetting of some alloys and high thermal stresses of the wave

I know nothing about Xbox specific rework, but have a lot of experience with PCB repairs. "...maybe think its a bad idea now not knowing what im doing" Don't get discouraged, it's a learning process. If it was that easy everyone would be doing it.

Very coo!!! [You have done an outstanding job of describing your situation.] I guess the via are connected to a BIG chunk of copper that affects your profile on that pad / ball. At the same time, run a profile each on a: * Void pad * Nonvoid pad

I have observed the same thing with solder composition in this case I am using 63/37 NC which is giving good results usualy. The liquid tin, product from MG Chemical that I used is to tinplates copper circuit on PC boards. I tried on few relays, it
