How to ensure quality in PCB Assembly Service?

We conduct a full range of quality tests including:

Consistent Batch Quality, Worry-Free Mass Production

Ensured stability and uniformity from the first board to full-scale production through automated lines and multi-stage process monitoring systems.

Our fully automated production lines ensure every PCBA—from prototypes to full-volume orders—meets the highest standards of quality and performance. With strict process control, standardized workflows, and real-time monitoring, we eliminate variability at every step.

Each board undergoes consistent placement, soldering, and inspection procedures, from SMT and reflow soldering to AOI and functional testing. This guarantees repeatability and accuracy, reducing common issues like prototype-pass but batch-fail scenarios and unstable solder quality.

Our scalable production system handles orders of any size without compromising consistency, improving delivery reliability and maintaining product integrity.

FAQ – Frequently Asked Questions

Full Electrical and AOI Testing for Zero-Defect Delivery

We ensure every PCB is defect-free with 100% electrical testing and Automated Optical Inspection (AOI) before shipment. Electrical testing uses flying probe testers and custom fixtures, checking critical parameters like continuity and impedance.

Our AOI systems detect micro-level defects like solder bridges and misalignment, ensuring quality at every stage of production. This thorough inspection process prevents errors and ensures reliable performance.
