Common Causes of Rosin Joints in PCB Processing
- 1) Process-related factors:
- a) Inadequate solder paste application
- b) Lack of solder paste
- c) Deterioration of steel mesh causing poor solder flow
- 2) Poor solderability of PCBs
- 3) Presence of via holes on the pads
- 4) Component pin distortion
- 5) Oxidation of component pins
It is important to address these issues to ensure high-quality PCB assembly.
