4 Layer Flexible PCB
Flexible printed circuits are circuit boards that have the ability to bend or twist. From this assertion, it is obvious that they are distinguished by a flexible construction. That is why electronic engineers and designers use them in applications that demand for their qualities. They are also referred to as flex circuits and are mostly used in small electronic applications. Since they are characterized by their ability to bend, flexible printed circuits are made of flexible substrate such as polyimide. Another important quality of flexible printed circuits is that they have superior heat dissipation than printed circuit boards. It is this quality that makes it possible for the electronics that use it to stay in quality condition for a long time.
HSX products cover 1~32L FR4 PCB, IMS PCB,HDI Boards, high frequency PTFE boards and Rigid-flex boards etc. It provides flexible quick turn production services (12 hours to72 hours), as well as small volume to big volume PCB manufacturing.Products are widely used in high-tech fields such as communications, power supplies, computer networks, digital products, industrial control, science and education, medical devices, and aerospace.

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.
And for big volume order, to save freight cost, we will suggest to
arrange the shipment by air or by sea, Of course, if you have your
own forwarder and can provide us the information, we can contact
them to arrange the shipment.
