Closed-Loop Quality Control

A rigorous 4-stage quality management system tailored for high-precision PCB manufacturing and PCBA assembly, ensuring zero defects from raw materials to final delivery.

IQC
Incoming Control
Strict admission control for substrates, components, and chemicals. Preventing defective materials at the source.
IPQC & FAI
In-Process & First Article
Mandatory First Article Inspection (FAI) combined with scheduled line patrolling for zero-deviation mass production.
FQC
Final Quality Control
Comprehensive visual and electrical validation to ensure every finished board meets IPC standards.
QA / OQC
Outgoing Assurance
Final verification of packaging, barcode traceability, and pre-shipment sampling to close the quality loop.

One-Stop Assembly That Saves Us Time

What we love most is the one-stop service. They handled the PCB fabrication, component sourcing, and assembly all in one order. When some parts were out of stock, they even suggested compatible alternatives without delaying the project.

Handled Our Complex High-Density PCB Perfectly

We had a high-layer count board with fine-pitch BGAs, and their assembly team nailed it. The X-ray inspection gave us full confidence in the hidden joints, and the functional tests passed on the first try. Great technical capability.
