My company is just getting into the flip chip packaging arena. We are putting in a prototype/small volume wire bond PBGA line. We have some questions with regard to choosing solder balls and cleaning of flux. 1) Is there a formula for the shrink

Robert: Expect a 0.033" raw ball to be within 0.022" of the pad, after reflow. To be clear, that�s not a matter of shrinking by 33%. The volume of solder on the pad is the same as the volume of solder in the raw ball. It�s just that the solder is

but we do not have laminate preheating on robots. There is no flux separate application, the flux is in the soldering wire
