The two most common design types are as follows: Typically, a four layer has two flexible layers and two rigid layers.Ī 6 layer combination rigid flex circuit has six conductive copper layers. Rigid zones may have more layers than flexible zones, and materials shift from FR 4 to polyimide in transition zones.Ī four layer combination rigid flex circuit has four conductive copper layers. Eliminates connection problems such as cold jointsĮvery rigid flex PCB is divided into zones that feature different materials and varying layer counts.Improves the ability of the circuit to transmit signals without loss.The lack of connectors and connecting cables accomplishes several things: Instead, the flex circuits electrically connect the system together. Because of the integration that occurs between rigid and flex circuits, a rigid flex design does not use connectors or connecting cables between the sections. By being able to design in three dimensions rigid flex designers can twist, fold and roll the flexible board substrates to achieve their desired shape for the final application's package.Īs with conventional PCBs, you can mount components on both sides of the rigid board. Rigid Flex designs are more challenging than the design of a typical rigid board environment, as these boards are designed in a 3D space, which also offers greater spatial efficiency. The flexible substrates are designed to be in a constant state of flex and are usually formed into the flexed curve during manufacturing or installation. 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 Printed Circuit Boards are boards using a combination of flexible and rigid board technologies in an application. Today, laptop computers, wearable technologies, medical devices, test equipment, and satellites are a few of the applications that rely on rigid flex PCBs. Higher component density and better quality control can be guaranteed. Flex Rigid PCB is connected by PTH (plated through holes). Rigid Flex PCB is an excellent combination of rigid boards and Flexible Circuits. The first commercially available mobile computer (which weighed a little over 25 pounds!) used rigid flex technologies. Rigid Flex PCB technologies trace back approximately 50 years to the need to replace wiring harnesses in spacecraft. In electronics, we sometimes encounter seemingly new technologies that have roots in the past. In order to let you have a deeper understanding of rigid Flexible PCB so as to select more suitable PCB products for your products, this article will give you a detailed understanding of the definition, type, application, manufacturing process, advantages, materials used in manufacturing, and stack up structure of rigid flexible PCB, And design guidelines. Rigid-flex PCBs improve reliability and lower costs associated with your device. We are manufacturing reliable Flex and Rigid-Flex PCB boards using most advanced process.
