The successful Rigid-Flex PCB Manufacturing Services from Eastwin

Are you thinking of using a rigid/flex format for a PCB? If so, the first and most obvious answer to the question ‘why?’ is to make use of the flexibility and to permit movement between two conventional boards – even if the movement is limited to providing vibration tolerance.

Flex circuits that actually flex in regular use can, however, be considered a special case; very often, the intent is to provide an efficient interconnect between two boards that do not lie in the same plane. In such cases, the flexible part may only flex during final assembly of the product and never do so again
Flex-rigid can be viewed as an alternative interconnect strategy or as cable replacement. One flex section replaces, at a minimum, a cable plus two connectors – which may be worthwhile for bill of materials reasons – and frees the volume the connectors would have occupied. This is significant for such products as wearables, where every mm3 within the enclosure is used, and in systems where two or more PCBs must be folded into place in final assembly. PCB fabricators report that products in which space and weight are at a premium are amongst the fastest growing adopters of flex-rigid technology.

Other benefits include: improved reliability, with fewer connectors and associated solder joints; and control of the signal path between the circuitry on the boards at either end of the flex.

Flex-rigid fabrication is a mature technology, with well developed rules for success. The first is to establish and maintain a dialogue with the board fabricator and to ensure that any modifications to design rules or design checks (DRC) are imported into the layout package in use and adhered to.

Rigid Flex Printed Circuit Board Manufacturer: What Eastwin Trading Ltd Offer

Rigid flex printed circuit boards (PCBs) are manufactured by combining rigid and flexible board technologies. These circuit boards are made up of multiple flexible circuit inner layers. An epoxy pre-preg bonding film is used to attach together these inner layers. The key benefit of these boards is that they are a combination of the best quality of flexible and rigid circuit boards. This can have several further benefits as far as stability, assembly, signal transmission, and overall size of the circuit are concerned. Rigiflex Technologies provides a number of variants in rigid flex PCBs, which include 4 layer rigid-flex with ENIG finish, 10 layer rigid-flex with 4 layer flex, 12 layer rigid-flex with heat sink, 14 layer rigid flex circuit boards, and many more. It is one of the leading rigid flex PCB manufacturers.
