Common Failures
Several recurring issues were identified during evaluation, including defective capacitors, defective diodes, and shorted power modules. There were also instances of cold solder joints and overheating. Additionally, improper application of conformal coating causing connectivity issues was observed.
Repair Approach
Repairs focused on replacing defective parts such as capacitors, diodes, and power modules. Cold solder joints were resoldered, and conformal coating was reapplied where needed. In cases of extensive damage, circuit boards were repaired and burnt traces were reconstructed.
Testing & Quality
Each unit underwent burn-in testing to verify functionality. Testing duration varied from 3 to 4 hours, involving output waveform observation and adjustments to ensure correct voltage outputs. All repairs were reviewed by technicians, and units were retested post-repair to confirm that issues were resolved.
