LC Polymer Flex Circuits Meet Electronic Assembly Needs

A line of flex circuits based on liquid-crystal polymer (LCP) dielectric film provides several enhanced properties required for demanding flexible-circuit applications. The circuits offer dimensional stability, chemical resistance, and high-frequency dielectric properties superior to those of polyimide, the most commonly used flex-circuit substrate.

The LCP flex circuits feature a low water absorption rate of 0.1% versus polyimide's 1% to 3%. As a thermoplastic polymer, an LCP film's high-temperature tolerance makes it compatible with soldering and wire-bonding operations. The LCP process creates fine-line features in a roll-to-roll format without adhesives or physical punching. The LCP flex circuit meets the needs of sophisticated electronic assemblies increasingly in demand for optoelectronic, medical, liquid-crystal module displays, microelectromechanical systems, disk drives, and high-frequency applications.

The company is providing customized prototypes of LCP flex circuits to selected electronics customers. Custom orders are accepted. Pricing greatly depends on volume and design.
