There are a few questions I have before we can answer this: 1. How are the die presented to the pick and place machine? (Tape, waffle Pak, tray) 2. What are the dimensions of the die (LxWxH)? 3. Are they bumped die? 4. What is the material of the

We agree with you. Recognize that these new solder connections have less metal and a lower standoff than similar BGA solder connections that have not been reworked. This could reduce the reliability of your product, somewhat. Flux or gel may be use

I guess I'll be different that the rest here. To stay consistent, I feel the best way is to use stencils to apply paste to the board first. We put paste on the board at SMT to solder them on initially. Then not when they get reworked? Why not tak
