Quality Control Process
Our comprehensive quality control process ensures that every product meets our strict quality standards.
Incoming Material Inspection
All raw materials undergo rigorous inspection upon arrival. We verify component specifications, batch numbers, and compliance with RoHS standards.
- Sampling per AQL 0.65 (MIL-STD-105E, Level II)
- Equipment: X-ray fluorescence (XRF) analyzer Olympus DELTA Premium for RoHS substance screening
- Records retained for 5 years per ISO 9001 §7.5.3
In-Process Testing
During manufacturing, each unit undergoes multiple testing stages including solder joint inspection, functional testing, and burn-in testing.
- 100% in-line functional test; sample-based AQL 1.0 for visual
- AOI (Omron VT-M120) + ICT (Keysight i3070) + Burn-in chamber (Espec PL-3KH)
- Burn-in: 8 hours @ 60°C, 110% rated load
Final Inspection & Aging Test
Before shipment, each product is thoroughly tested for electrical performance, mechanical integrity, and packaging quality.
- 100% final electrical test + 24h aging test (per IEC 62368-1)
- Chroma 8000 ATS + Hi-pot tester (Hipotronics HD115A, 5kVAC/6kVDC)
- Outgoing AQL: Critical 0 / Major 0.65 / Minor 2.5
Ongoing Monitoring & Reliability
We maintain product quality records and conduct periodic audits to ensure continuous improvement and compliance with ISO standards.
- Calculated MTBF > 500,000 hours per Telcordia SR-332
- Internal audit: semi-annual; Third-party SGS audit: annual
- Quality records retained 7 years; traceability by serial number
