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 continues 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.
