AOI + X-Ray Inspection

Every single board passes automated optical inspection and BGA/joint X-ray verification. No sampling — 100% coverage. Data logged per serial number.

±5%

Impedance Control

TDR-verified on every production panel. Critical for ADAS radar (77GHz), high-speed camera links (GMSL/FPD-Link), and automotive Ethernet (1000BASE-T1).

0 ppm

Field Failure Rate

Across 2M+ automotive PCBs shipped since 2018. Process FMEA, SPC on critical dimensions, and PPAP Level 3 documentation support zero-defect manufacturing.

Why IATF 16949 Matters

Not Just a Certificate.
It's a Manufacturing Philosophy.

IATF 16949 adds 37 specific requirements on top of ISO 9001 — all focused on defect prevention, supply chain traceability, and continuous improvement in automotive production. Every process change triggers a documented risk assessment. Every component is lot-tracked from receiving to shipping. Every defect gets a root-cause analysis with corrective action within 48 hours.

  • PFMEA on every production process, reviewed quarterly with cross-functional team sign-off
  • SPC on 14 critical dimensions — CpK ≥1.67 for all controlled characteristics
  • Full lot traceability — component reel → placement → reflow → test → ship, forward and backward
  • PPAP Level 3 documentation package on every new product introduction

Materials & Reliability

Engineered for 15-Year
Vehicle Lifecycles

Automotive PCBs must survive 15+ years of thermal cycling, vibration, humidity, and chemical exposure — without a single failure. Standard FR-4 doesn't cut it. We select laminates, surface finishes, and via structures based on the specific environmental profile of each application.

  • High-Tg FR-4 (Tg 170°C+) — standard for all automotive builds
  • Polyimide (Tg 250°C+) — for engine-bay and brake-system applications
  • Metal-core & thick copper (4-10oz) — BMS, inverter, and power-distribution boards
  • ENIG / ENEPIG / Immersion Silver — application-matched surface finishes for reliability

05

PPAP Shipment

Full DHR, CoC, SPC reports, test data. Barcode-level traceability. 99.2% on-time delivery.

Testing & Validation

Five Layers of Defect Detection.
Zero Escapes.

Automotive PCB failure isn't a warranty claim — it's a recall, a safety risk, and a supplier disqualification. Our five-layer inspection strategy catches defects at every stage so they never reach your assembly line.

  • SPI (Solder Paste Inspection) — 3D paste measurement on 100% of pads. Volume, area, height, registration. CpK ≥1.67.
  • AOI (Automated Optical) — Multi-angle cameras with AI classification. Missing, tombstoned, bridged, insufficient. <0.5% false positive rate.
  • X-Ray (BGA/QFN) — Void detection (>25% void = reject), bridging, head-in-pillow, insufficient ball collapse. 100% of hidden-joint packages.
  • ICT (In-Circuit Test) — Component value verification, short/open detection, diode/transistor polarity. Flying-probe for prototypes; bed-of-nails for volume.
  • FCT (Functional Test) — Application-specific functional validation at operating voltage, temperature, and load. Custom test fixtures per product.

Automotive-Grade Manufacturing Facility

Supplier Audit: 6 Questions for Automotive PCB Partners

1

"Show me your latest IATF 16949 surveillance audit report — not just the certificate."

Certificates are renewed every 3 years. The surveillance audits in between tell the real story: how many non-conformances, how quickly closed, any repeat findings. A clean certificate with repeat NCs in surveillance audits means the system exists on paper, not in practice.

2

"How do you handle a process change that could affect our approved PPAP?"

Any change to material, process, equipment, or location must trigger a customer notification per PPAP requirements. The supplier should describe a documented change-management workflow — not "we'd let you know."

3

"What's your containment process when a defect is found at final inspection?"

Automotive-grade answer: immediate quarantine, 48-hour root cause analysis, lot traceability to identify all affected boards, customer notification within 24 hours, corrective action with effectiveness verification. Not "we rework it."

4

"Do you do X-Ray on every BGA, or on a sample?"

For automotive, the answer must be every BGA on every board. Sampling-based X-Ray is a consumer-electronics practice. Hidden-joint defects (head-in-pillow, insufficient collapse) pass electrical test and fail in the field after thermal cycling.

5

"How do you ensure components stay available for a 10-15 year vehicle program?"

Component lifecycle database, EOL monitoring with 12-month advance notice, last-time-buy execution, pre-validated alternate sources. Without this, your ECU gets redesigned mid-program because a $0.50 LDO went obsolete.

6

"Show me your SPC data for the line that will build our boards — live, not a PDF from last quarter."

Real-time SPC on critical dimensions demonstrates process control. A manufacturer that can show live CpK data during your audit is genuinely running SPC. One that needs "a few days to prepare the reports" is running inspection, not control.
