PCB
Overview With ZITROK History

ZITROK ELECTRONICS CO., LIMITED is a professional company focusing on PCB & PCBA manufacture services.
We provide one-stop manufacture services of PCB & PCBA, including PCB production, material purchasing, SMT/PCBA, assembly test, etc.
We also provide complete and correct FAI test report, including the measurement of each material at
each position, abnormal material report and accurate judgment of design plan.


PCB Process Capability

We have a fully automatic plating and counterpart screen printing production line to provide high
high-quality PCB products to customers. In order to ensure the reliability of PCB, 10 sets of flying probe testers,
4 sets of test stand testers and high-accuracy FQC equipments are introduced.
