Cold Solder Joints: Both Wave Soldering and SMT Reflow Soldering Require Focused Prevention of Cold Solder Joints

Cold solder joint is a fatal defect common to wave soldering and SMT reflow soldering, with causes spanning multiple stages such as solder paste printing misalignment, oven temperature profile mismatch, PCB pad oxidation, insufficient flux activity, and conveyor speed fluctuations. Jia Jinyuan production line data shows that over 65% of soldering defects caused by cold solder joints stem from insufficient preheating and deteriorated interfacial wetting when nitrogen purity is below 99.99%.
