. All this information is important to us. Poor Wetting can be caused by contamination of the solder or improper solder temperature or conveyor belt moving too fast.

. Now we have the problem of poor wetting. The wave soldering diection is correct. My question is also is there difference between reflow soldering footprint and the wave soldering footprint

. Non Wetting Or De Wetting Non-wetting is an SMT defect that occurs when the base metal surface on the board doesn’t accept the molten solder, creating a poor joint condition where a component’s terminals

. Plasma removes contamination, impurities, and organics at the nanometer level – improving surface wettability, hydrophilicity, and bonding capabilities to address issues such as poor wetting, poor coating uniformity, voids, and poor adhesion

. The possible causes include too short contact time or low soldering temperature. This is evident by poor wetting, a non-smooth surface, and/or a chalky or grainy appearance
