Double Layer Flexible PCB
Flexible circuits (also called as flex circuits, flexible printed circuit boards, flex PCB, etc) are consisted of a thin insulating polymer film having conductive circuit patterns affixed thereto and typically supplied with a thin polymer coating to protect the conductor circuits. The technology has been used for interconnecting electronic devices since long long time ago. It is now one of the most important interconnection technologies in use for the manufacture of many advanced electronic products.
In practice there are many different kinds of flexible circuits, including one metal layer, double sided, multilayer and rigid flex circuits. The circuits can be formed by etching metal foil cladding (normally of copper) from polymer bases, plating metal or printing of conductive inks among other processes.
Advantage:
1)Accuracy of designs. Most of the advanced electronic devices in
use today use flexible circuit boards because of the high level of
precision expected of them.
2)They are lightweight. The circuit boards can be folded easily,
thus they can be positioned in compartments.
3)Long-term performance. The superior qualities of flexible circuit
boards allow them to have durability and long-term performance. The
characteristics of low ductility and mass contained in these boards
allow them to overcome the influence of vibrations, therefore
giving them the capacity to have improved performance.
4)Heat dissipation. Because of the compact designs of the circuit
board, there are shorter thermal paths generated and the
dissipation of heat is faster compared to other kind of PCBs.
5)Flexibility. Due to their ability to be flexible, it is easily to
bend flexible circuit boards to various levels when installing
them, thus make it possible to enhance the functionality levels of
various electronics.

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
