Silicon Technology (HK) Co.,Ltd.

We are Silicon Technology (HK) Co., Ltd who is Hong Kong PCB manufacturer in China. We have a good experience in manufacturing of PCB board. In order to let you know more of our company background, we have the company brochure and also a PCB specification form which is provided for our client to collect the PCB board information for quotation. Once the PCB specification form is received from you, we can provide our quotation to you within 30 to 60 minutes.
