We are continued to improve our MCPCB, FR4 PCB & Ceramic PCB manufacturing level to get satisfactory result from customers and ourselves. Currently our monthy productivity is 260,000 square feet (28,900 square meter), more than 100 different boards will be completed. We calso provide fast service, and urgent boards can be shipped out within 24 hours! For more information , please click here for lead time...

Follows are basic PCB production cabability, but we are not limited by that. If you would like some specail material, tighter tolerance or other requirements, you can Contact our stuff directly, we are going to answer any questions of MCPCB, FR4 PCB & Ceramic PCB at anytime.
