PCBA rework process involves several aspects: problem detection and analysis, component repair and modification, testing and validation of repair results, and so on. These steps ensure the reliability and good performance of the product during the manufacturing process.

Firstly, problem detection and analysis are crucial steps in PCBA rework process. During the manufacturing process, issues such as solder joint problems, component damage, and circuit connection errors may occur on the circuit board. By detecting and analyzing these issues, specific fault points can be accurately located and identified, providing guidance for repair work.

Secondly, component repair and modification are the core tasks of PCBA rework process. After identifying problems, defective components must be repaired or replaced. This may involve soldering, circuit connection restructuring, component replacement, and other operations. Repair work requires skilled technicians with extensive experience and precise operational capabilities to ensure that the repaired components function properly.

Once repair work is completed, testing and validating repair results are essential steps in the PCBA rework process. This verifies the effectiveness of the repair work and ensures that the repaired product operates normally. Testing processes may include functional testing, performance testing, electrical testing, and other aspects to ensure product quality and stability.
