How to Solve the Defects of Wave Soldering Technology
Wave soldering is an essential equipment for plug-in soldering of electronic products, but soldering defects are often encountered due to various reasons during wave soldering. So what is the cause of the defect? How to solve these defects? 1. Solder Projection Reason: 1) Improper PCB transmission speed; 2) Preheat and low tin pot temperature; 3) PCB transmission angle is small; 4) Bad wave crest ; 5) Flux failure, poor solderability of component leads. Solution: 1) Adjust the transmission speed until appropriate; 2) Adjust the preheating temperature and tin pot temperature; 3) Adjust the PCB transmission angle; 4) Optimize the nozzle and adjust the wave crest shape; 5) Replace the new flux and solve the lead wire solderability problem. 2. Pseudo Soldering Reason: 1) Poor solderability of component leads; 2) The preheating temperature is low; 3) Solder...
