Engineering reliable power devices through end-to-end stringent control, providing stable semiconductor 

assurance for industrial and high-end manufacturing.

Quality Policy

Quality First, Efficiency First, Customer Centricity. We are committed to the continuous iteration of our quality 

systems in the relentless pursuit of zero-defect delivery.

Systems & Certifications

Full Compliance: Entire product range adheres to RoHS 2.0 and REACH environmental directives.

MSL1 Rating: Packaging achieves Moisture Sensitivity Level 1, ensuring long-term storage without the need for 

pre-assembly baking.

Quality control is applied across the entire production process:Full-process quality, governance from design to delivery.

1. Incoming Material Control (Source Control)

Wafers are sourced exclusively from Tier-1 foundries, followed by 100% electrical and reliability re-inspection upon arrival.

Critical materials are fully traceable with strict unique-batch management protocols.

2. Process Control (Manufacturing & Assembly)

SPC Monitoring: Statistical Process Control is implemented across all assembly and testing phases, featuring real-time 

alerts for critical parameter deviations.

Elite Environment: ESD protection is strictly implemented, and manufacturing environments are aligned to automotive-grade 

cleanroom standards in terms of electrostatic control and temperature/humidity management.

Defect Management: Stable control of defect rates maintained below 100 PPM (0.01%).

3. Reliability Validation

JEDEC Standard Execution: High-Temperature High-Humidity Bias testing at 85°C/85% RH for 1,000 hours.

Comprehensive Stress Testing: Full verification of temperature cycling, high temperature storage, withstand voltage shock, and lifespan aging

Assurance: 100% electrical testing of every batch prior to shipment to ensure zero leakage of non-conforming units.

4. Traceability & Customer Service

End-to-End Traceability: Seamless batch tracking from wafer fabrication and packaging to final testing.

Rapid Response: Prompt 24-hour technical support to accelerate Failure Analysis and the implementation of corrective actions for seamless issue resolution.

Operational Excellence: On-time delivery rate ≥99%; Customer satisfaction rate ≥98%.
