We integrate quality control into turnkey services. Watch our factory video!
Once we receive your Gerber and BOM, we will do a free and professional DFM, ensuring your Gerber and BOM are error-free, and suggest optimization if any is needed in your project.
In PCB fabrication, we set up a complete training mechanism to ensure standard operations.
Meanwhile, we custom-adjust the PCB process according to your project, insist on equipment maintenance, and promote an abnormality-solving mechanism. Every effort is made to optimize quality management and meet product quality requirements.


At PCBONLINE, quality control is integrated into our PCBA process. All components, PCB boards, and fixtures undergo strict lQC(incoming quality control) before PCB assembly.
During SMT assembly, solder paste inspection and dual AOl (automated optical inspection) before and after reflow soldering ensure SMT soldering reliability.
For through-hole assembly, QC checks are applied before and after wave soldering, with cleaning when needed.
Every finished PCBA goes through functional testing, followed by FQC(final quality control) and FQA (final quality assurance) to meet lPCA-610 standards. With this multi-level QC system, we guarantee stable, high-quality PCBA for both prototypes and mass production.
PCBCONLINE quality control (QC) laboratory is part of our OEM quality center. It ensures every PCB/PCBA box-build meets strict standards from start to finish. We test incoming materials, monitor production, and inspect final PCBA assemblies.
Our lab is equipped with comprehensive and advanced equipment and experienced engineers to conduct performance, reliability, and environmental tests.
We also collaborate with CNAS-certified third-party labs to meet OEM testing requirements. Every result is accurate and trustworthy.
With PCBCONLINE, terminal companies from multi-national companies to startups, business makers, can rely on consistent, reliable performance, and fully-tested OEM PCBA and final devices.


PCBCONLINE ensures the integrity of every component, especially active and high-value ICs.
Strict component and material management ensures the high reliability of PCBONLINE's PCB assembly and box-build services.

Our OEM PCBA factories in Jiangsu and Jiangxi Provinces have built complete quality
management systems, including ISO, IATF, REACH, RoHS. Please view our
