The printed circuit board is the main component of electronic products. Its appearance directly impacts the appearance, service life and reliability of the product.

PCBA Repair is a very important task.

PCBA Boards: Why They Look Bad

Poor soldering, damaged PCBs, and damaged components are all possible causes of the bad appearance.

1. PCBA Boards that Look Bad Are Often Due to Poor Welding

Inadequate welding temperatures, insufficient welding time, and inappropriate welding flux are all possible causes of poor welding.

Re-soldering is a way to fix bad soldering.
