Do you mean "how to solve or reduce this defect at wave soldering process" while continuing to use-up my SACX solder? If so, try: * Smaller solder volumes lower shrinkage hole / hot tears [Higher hole diameter versus pin diameter helps in reducing v

Hi all, I think Hot Tear or Shrink Hole defect is common in LEAD FREE wave soldering, especially those solder is from SAC type. As far as I know, it is related to cooling rate. Is there anyone know how to solve or reduce this defect at wave solder

Yes, continue to use SAC solder. However, as far as I know, the problem become more severe when cooling rate is increased.
