Voids in solder joints are considered one of main defects in Printed Circuit Board Assemblies (PCBAs). The reason for the formation of solder voids is mainly caused by the organic volatile matter in the flux of solder paste that cannot effused timely

There are no criteria for Bottom Terminal Component (BTC) solder void except 30% area for BGA solder joints in IPC-A-610F. It means supplier and customer should co-define the criteria for their own products. The solder void ratio control is related t
