We have a good research and development team, committed to the design of consumer electronice product.  2018, we
began to  have electric toothbrush, bule headset and 3D advertising machine products.

We accept CAM350,GC-CAM,Gerber,Gerber 274X,Protel99SE,Eagle file,DXP,Power PCB data for PCB manufaturing.

Our experienced
  engineers who understand customer's requirement very well ensure Smooth and fast communication 
and feedback with customers.
Besides,they can give valued suggestion from customer's design.
