Hi, Does anyone know where I can find some sort of standard for BGA's? We have done quite a bit of BGA rework and some of the results are less than spectacular when viewed with the X-ray machine. For example, on a lot of the boards the ball seems to

The last statement saying that seeing down the bga component with these systems is useless, is an incorrect statement. First with x-ray you do not see flux residue and or flux migration, second with x-ray you do not see a cold solder joint. Visual i
