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.
