Flexible PCB is one of the major PCB type that we manufacture. It is becoming more popular due to the expanding market of wearable device.
Flexible PCB(FPC) also includes a sub-type called rigid-flex PCB which combines traditional rigid PCB and work with flexible parts together.
Quite a number of flexible PCB manufacturers in China are small and mainly hand work, but in Chee mau we are using advanced equipment to make the production automated, thus our FPC are with stable quality and we have a good capability of mass production.

small volume, light weight. Can be placed in tiny, high-density electronics.
flexible, bendable. Can be placed in any geometry equipment.
can be dynamic flexible other than static flexible.
can expand at 3 dimensions, increase the circuit design and industrial design possibility.
except working as a normal circuit board, a FPC can also be work as induction coil, electromagnetic shielding, touch switch on-off button, etc.
