With 15 years trackable, up-and-down history in PCB manufacturing industry, Chee Mau now is one of the dazzling PCB supplier in western China.

We started as a rigid PCB manufacturer in Canton province in the summer of 2005, called CM electronics. A few years later, in the answer of the calls from our founder's motherland, we moved to Sichuan province and founded Chee Mau.


Later of the story, Chee Mau invested and partnered with carefully selected PCB manufacturers, to continue working in PCB industry as a comprehensive supplier. It extended business from rigid PCB to membrane switches, as well as ceramic PCB and PCB assembly service.


With all those times passed, Chee Mau has gained a lot of global partners who are satisfied with our circuit boards and assembly service. Some of them are giants in their specific industry, some of them are start-ups still. We are grateful for all of our customers trust.



Our rigid PCB manufacturing plant locates in Suining, city with over 1200 employees. It ranked in the 70th among all the Chinese PCB manufacturers and focus on the production of FR4 rigid PCB. 

The factory has two comprehensive PCB manufacturing plants, one for prototype to small order and another one for mid to serial PCB production, technically the factory has a monthly capacity of 120K square meters.
