What are Rigid Flex PCBs?

Definition and structure of rigid-flex circuit boards

Rigid-flex circuit boards mix rigid and flexible parts in one design. The rigid sections give strength, while the flexible parts can bend or fold. This mix lets engineers make small and complex designs that regular PCBs can’t handle.

Rigid-flex PCBs come in different types based on layers and uses:

• Type 1: One layer with a single conductive surface, good for bending.
• Type 2: Two layers with holes for better connections in flexible designs.
• Type 3: Three or more layers, often used for designs that don’t move much.
• Type 4: Combines many layers of rigid and flexible materials for tough designs.

This special design makes rigid-flex PCBs perfect for industries needing small, strong, and dependable electronics.
