Although conventionally taked interior welds fusing point higherS-Sn40PbA solder, the lower S-Sn60PbA solder of fusing point for outside weldings, and control when weldingBetween method, but all can not stop infringement that inner solder joint is caused. The fusing point of S-Sn40PbA solder is183～238 DEG C, the fusing point of S-Sn60PbA solder is 183～190 DEG C, and both are difference to some extent, but incipient meltingTemperature is identical, that is to say that two kinds of solders melt deliquescing simultaneously, and the welding temperature of general soldering compares prickerMaterial fusing point wants high 60～80 DEG C, just can make the complete melting of solder, ensures quality of welding spot. Control weld intervalMethod also infeasible: each operator feels different to 1～2 second time, and exists in realityAfter welding, need the situation of reprocessing. Weld interval, the too short outside weldings solder that can affect melted, and caused " hardThe heart ". After product is sold, user is in welding outside lead process, and more difficult control weld interval, to insideThe infringement that solder joint causes is inevitable, thereby has reduced the reliability of product.
