Manufacturing

A factory built around one number: zero defects.

250,000 sq ft of fabrication, assembly, and test — vertically integrated so quality is engineered in, not inspected in.

Capability 01

Wafer Fab & Die Processing

01
150mm / 200mm wafers0.18 µm – 1 µm nodesClass 100 cleanroom

Mature-node fabrication optimized for analog, mixed-signal, and power devices — where reliability and repeatability matter more than raw density.

Capability 02

SMT & Module Assembly

02
14 SMT lines01005 placement3D SPI + AOI on every line

High-speed surface-mount lines with closed-loop inspection, plus selective soldering and press-fit cells for connector and module assembly.

Capability 03

Automated Test & Burn-In

03
100% electrical test168 h burn-in capacity±0.05% measurement accuracy

Every component is tested against its datasheet, not sampled. Burn-in chambers and thermal-cycle testing screen out early-life failures before shipment.

Capability 04

Packaging & Traceability

04
MSL-controlled packingLot-level genealogy2D data-matrix marking

Moisture-sensitive devices are baked, sealed, and labeled per JEDEC. Every reel and tray traces back to wafer lot and raw material certificates.

Quality & Reliability

Five gates between raw material and your production line.

Quality is built into the process with documented checks, traceability, and ongoing reliability monitoring at every step.

  1. 01Quality gate

    Incoming Material Qualification

    Certificate verification, XRF screening, and supplier audits on every raw-material lot.

  2. 02Quality gate

    In-Process SPC

    Cpk ≥ 1.67 targets on critical parameters, with automated line-stop on drift.

  3. 03Quality gate

    Outgoing Quality Assurance

    AQL-based final inspection plus 100% electrical test — 99.98% outgoing yield.

  4. 04Quality gate

    Reliability Monitoring

    Ongoing HTOL, THB, and temperature-cycling on production samples every quarter.

  5. 05Quality gate

    Failure Analysis Lab

    In-house X-ray, SAM, decap, and SEM — 8D reports within 10 working days.
