Quality Control Process

A controlled workflow for stable production — with inspection records and traceability.

STEP 01

Incoming Inspection

Reduce wrong parts & counterfeit risks before production.

  • IQC for key components (visual, marking, package check)
  • PCB appearance + dimensional checks
  • BOM/AVL alignment before kitting
STEP 02

Solder Paste Inspection (SPI)

Catch paste volume/offset issues early to prevent rework later.

  • Paste volume monitoring & trend control
  • Stencil alignment validation
  • Process window checks at start-up
STEP 03

In-Process AOI

Detect placement & solder defects fast — with immediate feedback loop.

  • Real-time visual inspection on SMT lines
  • Immediate defect feedback for process correction
  • Coverage per project requirements
STEP 04

X-Ray Inspection (as needed)

Verify hidden joints on BGA/QFN to reduce field failures.

  • BGA/QFN hidden solder joint verification
  • Void analysis & solder integrity review
  • Used when design/package requires
STEP 05

ICT / Functional Test

Confirm electrical performance before shipment — not after you receive it.

  • ICT for opens/shorts & key nets (when applicable)
  • Functional verification under defined load/conditions
  • Test plan aligned to your requirements
STEP 06

Final Inspection & Packing

Ship with documented results and ESD-safe packing for transit reliability.

  • Final QC check + packaging control
  • ESD-safe materials and labeling
  • Shipment documentation aligned with your request
Note: AOI/X-Ray scope and test deliverables are defined based on your project requirements. Inspection records support traceability and quality control.
