. An opposing school of thought was that voids act as crack arrestors, which improve solder joint life. The root cause of voids in BGA solder joints is well understood by the electronics industry with a number of papers published on the topic [1, 2, 3]. R

I.C.T-LV733 How to solve the problem of void, there will be use vacuum reflow soldering machine. Soldering in vacuum environment can fundamentally solve the oxidation of solder in non-vacuum environment, and due to the effect of internal and external pressure difference of solder joint, the
