We are experiencing some difficulty in BGA assembly and would like to do some periodic on site dye and pry after different assembly processes. Does anyone do this now? Is it actually feasible? Does anyone have recomendations on equipment/dye suppliers?

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.
