The rigid flex PCB design process requires a careful consideration of several key factors. These include industry rules, size and shape constraints, board stackup requirements, and possible design optimization solutions. The aim of this guide is to shed light on these considerations and help you determine the best way to design a rigid flex PCB.

Rigid Flex PCB Design
Rigid flex PCB design is the process of creating a printed circuit board that combines the rigidity of a standard rigid PCB with the flexibility of an interconnecting flex circuit. This combination allows for more efficient use of space and easier connections. It also reduces PCB weight when compared to traditional rigid designs.

During the design process, engineers use software tools to create a model of the PCB. This model is used to represent the board stack up, size and shape requirements, and all other details necessary for a successful rigid flex PCB design.

Given their unique features, designing rigid flex PCBs requires adherence to industry rules and other requirements. Below, we take you through the main factors when it comes to PCB design for rigid flex boards.

Rigid Flex PCB Design Guidelines
How do you ensure a successful rigid flex PCB design? While specific design rules can vary depending on the application, some general guidelines apply and should be followed. These include rules for the rigid flex PCB materials, stackup, bend radius, impedance, and via features.
