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.
