FAQ:
Q1: How can I get a quotation?
A: Please send us gerber file with format Gerber, PROTEL 99SE, PROTEL DXP, POWER PCB, CAM350, ODB and provide the demand quantities. We will provide quotation accordingly.

Q2: Can you manufacture the PCBs from a picture file?
A: No. But if you can send us a sample PCB, we could clone its design and work it out.

Q3: Do you have PCB in stock.
A: Most of the PCB boards are customized, and they have different designs, we produce them according to the gerber files provided by customers.

Q4: What FR4 materials do you usually use?

A: Kingboard, ITEQ, Shengyi...

Q5:What kind of shipment way do you usually use?
A: For small volume order, we always suggest to ship the boards by DHL,UPS,FedEx door to door service, we could use your shipping account to do collection or use our account to ship in DDU (import duty unpaid) delivery term.
