Services Summary: PBC manufacturing, PCB assembly, cabling, enclosures, keypads, stencils and components, one-stop turnkey services and design consultation
Flexible PCB Services: Flex PCB support: Components mounted on flexible plastic substrates, such as polyimide, PEEK or transparent conductive polyester film. Additionally, flex circuits can be screen printed silver circuits on polyester. Flexible electronic assemblies may be manufactured using identical components used for rigid printed circuit boards, allowing the board to conform to a desired shape, or to flex during its use. Rigid-Flex PCB support: Flexible and rigid board structures are bonded together in the same units as one part of so called rigid-flex boards. Most rigid flex boards consist of multiple layers of flexible circuit substrates attached to one or more rigid boards externally and/or internally, depending upon the design of the application. Rigid-Flex PCBs contain a flexible part with an insulating layer and a conductor layer, and a rigid part with circuit wiring.
