Flex PCB

Single layer to 12 layer flex PCB manufacturing service. Different stiffener materials: Fr4, PI, Aluminum, different flex materials such as Doupont, Panasonic etc are available.
A flexible board is made of flexible insulating material, which has many advantages that a rigid printed circuit board does not have. For example, it can be freely tortuous, winding, and folding, can be arbitrarily organized according to the spatial layout requirements, and can be arbitrarily moved and expanded in three-dimensional space, and then reach the integration of components and wire connections. Using FPC can greatly reduce the volume of electronic products, suitable for electronic products with high density, miniaturization, and high reliable direction development needs. Therefore, FPC has been widely used in aerospace, military, mobile communications, portable computers, computer peripherals, PDA, digital cameras, and other categories or products. Fastlink can provide high-quality flexible circuit board manufacturing and assembly services.

Benefits of Flex PCB Fabrication


With the high-speed development of electronic products towards short, small, light, and thin, the amount of FPC flexible boards is increasing with so many benefits:

01.
Thinness
With high flexibility, can reduce the volume of the product, according to the space limit to change the shape.

02.
Flexible
Three-dimensional wiring, and folding winding, are conducive to product design, but also reduce assembly time and errors.

03.
Stable
Stable chemical performance, can improve the service life of the product, prevent static interference, safe and reliable.

04.
High Temperature Resistance
With high and low-temperature resistance, fire resistance characteristics, good heat dissipation performance, multiple functions, and low cost.
