Rigid-Flex PCB:


Rigid-Flex printed circuit boards are designed to provide solutions, and act as replacements for rigid PCBs. As the


name suggests, these circuit boards are a hybrid of flex and rigid circuits. The advantage of this type is that they


exhibit the benefits of both rigid as well as flexible circuit boards.Most rigid-flex circuit boards consist of multiple


layers of flexible circuit substrates attached to rigid boards externally and/or internally. The flexible substrates


are designed to be in a constant state of flex, and are usually formed in a flexed curve during manufacturing or


installation. This is dependent upon the design of the application


Rigid-Flex PCB

Features of Rigid-Flex PCB:


  • The designing of this board is a little bit difficult compared to a rigid circuit board because this module is designed


      according to a three-dimensional environment that also provides high spatial efficiency.


  • The main benefit of this board is that it provides highly flexible, decreases flex thickness and less expensive circuit




  • As on the tradition printed circuit board we can assemble large no of components on any side of a rigid circuit




  • Since the incorporation that exits among rigid and flex circuitry, a rigid-flex assembly does not use connectors


     among the  units. In its place, the flex circuitry electrically joins the scheme together.


  • The absence of connectors provides some benefits that are mentioned here.


  • It increases the capability of circuitry to send a signal with less distortion.


  • Houses precise impedance value.


  • It reduces joining issues like cold connections.


  • It also decreases the weight of the board.


  • Each rigid-flex printed circuit board divided into different parts that have different categories of layers and quantity.


  • The number of layers can be larger than the flexible portion and construction substance can be 


     FR4 (Flame Retardant) or polyimide.
