Design Considerations

Bend Radius

Dynamic applications require minimum 10x flex thickness, while static applications can use 6x thickness. Proper bend radius ensures long-term reliability.

Copper in Flex Areas

Hatched or crosshatched copper patterns improve flexibility and reduce stress concentration. Solid copper planes should be avoided in dynamic flex areas.

Transition Zones

Gradual transitions between rigid and flex regions minimize stress points. Staggered layers and smooth transitions improve mechanical reliability.
