Pin holes in the solder joints on various devices can be an indicator of something amiss with the solder paste itself. Solder paste storage may be a concern. Do you possibly have someone putting paste back in the refrigerator after use? Are you tr

Recently, there has been an upsurge in the Pin Hole/Blow Hole problem in our wave soldering process. We are baking the PCBs for 2 Hrs. at 125 degree C. The Wave Soldering profile seems to be O.K. Still the problem is persistent. Can somebody help

Defects will result, Your cooling rate is affected because the hot air is not circulated properly. Outgassing will appear and you'll have pin holes / blow holes, disturbed joint etc. Correct me guys if i'm wrong. Thanks
