PROJECT-DEFINED QUALITY CONTROL
PCBA Quality Control and Traceability
Quality is not inspected at the end, but predicted throughout the entire process. We invest not in inspection equipment, but in manufacturing stability and customer trust.
QUALITY PHILOSOPHY
Quality Philosophy
Quality is not inspected at the end, but predicted throughout the entire process.
We invest not in inspection equipment, but in manufacturing stability and customer trust. Every inspection process is designed to discover risks earlier, not just catch defects.
Quality is Predicted
Through DFM review and material assessment during NPI phase, we predict and prevent risks before they occur. We solve problems before they happen.
Quality is Everyone's Responsibility
From incoming materials, SMT, testing to shipping — every step has quality gates. Not more inspection, but every process step being accountable for final delivery.
Data Supports Trust
MES and automated testing can capture the material, process and test records defined for an approved project.
Continuous Improvement Creates Value
SPC statistical process control, 8D reports and PDCA cycles support project-specific issue prevention and continuous improvement.
SIX PILLARS OF QUALITY MANAGEMENT
Six Pillars of Quality Management
Our quality system is built around six pillars, forming a complete quality assurance loop.
Quality Upfront
QUALITY UPFRONTDFM manufacturability review + material availability assessment to identify risks during design phase.
Process Control
PROCESS CONTROLFAI first article confirmation + SPC statistical process control + inline inspection (SPI/AOI) for real-time process stability monitoring.
Test & Validation
TEST & VALIDATIONICT in-circuit test + FCT functional test + X-ray inspection + burn-in testing to ensure complete validation before shipment.
MES Traceability
MES TRACEABILITYUnit-level serialization with 8-stage process traceability — customers can trace the manufacturing history of every product by batch number.
Continuous Improvement
CONTINUOUS IMPROVEMENTSPC monitoring + 8D reports + defect rate trend analysis — upgrading from post-inspection to full-process quality prevention.
FULL-PROCESS QUALITY CLOSED LOOP
Full-Process Quality Closed Loop
From NPI to shipment confirmation, six interconnected steps form a complete quality control loop.
New Product Introduction
DFM manufacturability review, identifying design risk points
Process Planning
Develop control plans and SOPs, define quality standards for each process
Incoming Control
IQC incoming inspection to ensure materials meet specifications
Manufacturing
FAI first article + SPC inline monitoring + AOI/SPI inspection
Test & Validation
ICT, FCT, X-ray inspection, and burn-in testing to ensure complete functionality
Shipment Confirmation
OQC outgoing inspection + MES data completeness verification
TESTING & VALIDATION CAPABILITIES
Testing & Validation Capabilities
Six testing capabilities covering comprehensive verification from soldering to functionality.

SPI
Solder Paste Inspection3D SPI inspects solder paste volume, area, and height to ensure printing quality.
AOI
Automated Optical InspectionDetects solder joint quality, component offset, polarity errors, missing components.
X-ray
X-ray InspectionIdentifies BGA/LGA solder voids, bridging, head-in-pillow and other internal defects.
ICT
In-Circuit TestTests resistance, capacitance, diode parameters and soldering quality of passive components.
FCT
Functional Circuit TestVerifies product functionality meets design specifications.
Burn-in Test
Burn-in / Aging TestHigh-temperature high-humidity aging test to screen early failures and verify long-term reliability.

MES DATA TRACEABILITY
MES Data Traceability
Unit-level serialization with end-to-end traceability — making quality visible.
Unit-Level Serialization
Every product has a unique SN serial number, bound throughout the process from SMT to shipping
8-Stage Process Data Capture
Solder paste printing → placement → reflow → AOI → X-ray → ICT → FCT → shipping, complete data captured at every process stage
Real-Time Visualization
Yield trends, defect distribution, CPK values displayed in real-time — quality status at a glance
Traceability Review
Available manufacturing history can be queried by batch or serial number according to the approved project scope
SUPPLIER QUALIFICATION
Verify quality-system evidence against the correct entity
Buyers who need certification evidence should state the project and supplier-qualification requirement. A specific claim is provided only when the certificate-holder legal entity, certificate number, scope, validity, and certificate document or issuing-body evidence all match. Until then, this page does not display certification names, badges, or suggestive certificate imagery.

FAQ
Frequently asked questions about quality management.
Contact Our Quality TeamQuality management covers design review, process control, test validation, production traceability and continuous improvement. Project-specific procedures, records and supplier-qualification evidence are checked against the request; certification claims are provided only after the certificate holder and evidence are fully matched.
FAI validates agreed dimensional, visual, soldering and functional items on initial samples before volume production. Inspection scope and release criteria follow the project files and confirmed quality requirements.
Material batches, key process records and test results can be recorded according to project scope. Available fields, retrieval method and retention requirements are confirmed during project review.
SPC monitors the key process parameters and trends agreed for the project. Control items, alert rules, response actions and required records follow the confirmed control plan.
When a project or customer requires 8D, the team records problem definition, containment, root cause, corrective action, verification and prevention. Delivery timing is confirmed for the project.
Temperature, duration, load and cycling conditions are defined from the product application, risk and customer-specified standard. The test plan and acceptance criteria are confirmed before execution.
