China PCB Manufacturers: How to Choose and Verify
1 resources tagged with "Pcb Manufacturer"
China's PCB sector spans prototype shops in Shenzhen turning bare boards in 24-48 hours to listed high-volume fabs like those clustered around Zhuhai and Jiangmen. Capability tiers matter: a 2-layer FR-4 shop is not the same as a fab that can hold ±0.075mm registration on 8-layer HDI with controlled impedance. Before you commit, confirm the factory actually fabricates in-house versus brokering your order to a third plant.
When sourcing a PCB manufacturer you are buying process control, not just price per square decimeter. Check for UL 94V-0 laminate, IPC-A-600 acceptance class, and whether they run AOI and flying-probe or E-test on 100% of boards.

FAQ
What MOQ do Chinese PCB manufacturers require?
Prototype shops accept 5-10 pieces with no real minimum, while volume fabs typically want at least 1-5 square meters of panel area. For a small board you can often hit volume MOQ at a few hundred to a few thousand pieces.
How do I verify a PCB factory's certifications?
Ask for the UL file number and check it directly on UL Product iQ, and request a recent ISO 9001 certificate plus IPC class statement. A real fab will share AOI and impedance test reports per batch.
How long does PCB fabrication take in China?
Standard 2-4 layer boards run 3-7 working days; 6+ layer HDI or controlled-impedance boards take 7-12 days. Add 5-10 days for sea freight or 3-5 for air on the back end.
