Hi there. We have had an out of control reflow oven that has allowed its temperature to fluctuate by up to +/- 20 deg C from set point in very short periods of time. We found the root cause of the problem and fixed it, but by then we had already run

Have you check the flux gravity lately? If not, Check the flux gravity every 6 hours to make sure proper parameters are meet. Here is a list of things that may cause your solder ball problems; Excecive heat, defective fixtures, preheating temperature

I am sure that you did a reflow profile.... right ?
