Industrial power electronics manufacturing lines

Incoming component verification

Surface-mount assembly inspection

Full-load burn-in validation

Final dielectric and packaging checks

Incoming raw semiconductors, copper transformers, and capacitors undergo rigorous sample spectrometry, tolerance verification, and dielectric breakdown testing before warehouse intake.

Automated optical inspection scans high-density PCB solder joints post-reflow, followed by automated selective conformal coating application to resist humid ambient operating environments.

Assembled units run inside dedicated thermal chambers under continuous 100% rated resistive and inductive loads for four hours to catch early component failure.

High-potential insulation testing, pure sine wave harmonic distortion verification, and heavy-duty export pallet strapping complete the final dispatch sign-off.

Thermal and electrical stress validation

Environmental burn-in chambers

Inverter subassemblies endure elevated 50°C chamber conditions under dynamic step loads. Calibrated data loggers monitor internal heat sink thermal derating curves to ensure pure sine wave output stability under tropical installations.

Harmonic waveform analysis

Computerized digital oscilloscopes inspect switching transient voltages, total harmonic distortion under 3%, and high-potential insulation resistance across every completed batch before serial registration and boxing.
