Every PCB Inspected from Raw Material to Shipment
Quality Control
Three layers of defense — IQC incoming inspection, IPQC in-process monitoring, FQC final testing — ensure zero-defect delivery. ISO 9001 & IATF 16949 certified.
INCOMING QUALITY CONTROL
IQC Incoming Material Inspection
Every batch of laminate, copper foil, prepreg, and chemicals is tested per IPC-4101 standards. We only accept UL-certified tier-1 suppliers to eliminate quality risks at the source.
- 01
Laminate Tg, Dk/Df verification per IPC-4101
- 02
Copper foil thickness and peel strength testing
- 03
Chemical solution concentration titration
- 04
Supplier audits and material batch traceability ensure every laminate source is verifiable
- 05
Reject rate tracking and supplier scorecards
IN-PROCESS QUALITY CONTROL
IPQC Real-Time Process Monitoring
AOI automated optical inspection, XRF copper thickness measurement, SPC statistical process control — every critical step is data-driven. Cpk ≥ 1.33 is our baseline.
- 01
AOI (Automated Optical Inspection) on inner and outer layers
- 02
Line width and spacing measurement with LDI feedback loop
- 03
XRF copper thickness measurement on every board for uniform plating
- 04
Solder mask adhesion and hardness testing
- 05
Real-time SPC charting with Cpk ≥ 1.33 target
FINAL QUALITY CONTROL
FQC Final 100% Inspection
100% electrical testing + cross-section analysis + ionic contamination testing — triple verification for zero-defect shipment. Every board comes with a complete inspection report and production traceability code.
- 01
100% flying-probe or fixture electrical test
- 02
Cross-section microsection analysis per IPC-6012
- 03
Ionic contamination testing (ROSE method)
- 04
Solderability testing per IPC-J-STD-003
- 05
Full inspection report with photos included in shipment
