Consider using 100% nitrile gloves or finger cots. They are ESD safe and will not break out the skin like latex will. Cotton can absorb flux, solder, etc and will leave a lint residue however it is considered ESD safe.

We do what you currently do for lead free rework. Why are you worried about copper dissolution? I think I'm missing something

Copper dissolution is a major issue in lead-free soldering, but only when you use OSP boards. Nickel based plating eliminates the problem.

Hello Dougs: Have you tried stenciling solder paste to the BGA part itself. You will find this most helpful for your heat transfer and attachment integrity of the component in a Pb free process.

Thats something i've been thinking about, what about other types of SMT component, QFP, QFN, etc etc?? What is everyone out there doing?

When reworking a BGA, we apply paste, inspect alignement with a camera and then proceed with the temperature profile. For the majority of the other components easily side accessible we do them by hand soldering.

I find it hard to believe that AIM never contacted you either by the rep or directly. I switched to AIM solder 4 years ago after using several of their competitor�s pastes for the very fact that the products were as good but Aim�s technical support w

AIM contacted me the day after I posted this on SMTnet. I have still not heard anything back from my AIM rep.

Any one familiar with a board clamp problem on MPM UP3000? The one I have will not clamp the board when program is running. It will work when toggled through the output diagnostics. Any help is appreciated.
