Well the profiler IS out for calibration so I can't use it. However, what piqued my curiosity is your statement concerning uneven heating. On the product we were running we had several non-liquidous solderjoints where as the rest of the joints looke

We had a vent block up not too long ago ourselves. Saw multiple solderjoints, especially on fine pitch micros, that looked like they had alligator toes. We solder bump, so it was obvious that area didn't get hot enough to liquify the solder and hav

You want the backplate set up so that when there's no PCB the wave stands still or moves towards the PCB. When the PCB moves over the wave, it should just pull the wave towards the back (in the same direction as the PCB). This will help reduce brid

We also use machinists dye. I like to pull a vacuum on the board after wicking the dye under the BGA. It seems to help fill fine cracks. I'll stick it in a warm oven if I'm in a hurry for the dye to dry. Then just bend the board to pop off the BGA.
