Flex Circuits Overview

APPLICATIONS

Static v. Flex to Fit:

Static; the flex circuit is installed flat between two or more stationary parts.

Flex to fit; the flex circuit is bent or molded into position then installed between two or more stationary part.

Dynamic:

The flex circuit is installed between one or more moving parts.

Bend radius:

Single-sided flex 6X circuit thickness.
Double-sided flex 10X circuit thickness.
Multilayer flex 10-15X circuit thickness.
Dynamic Application 20X circuit thickness.

Every day we read or hear about how a healthy life is about balance.  There are only two things my dad critiques me about when it comes to my health: “sit up straight and stretch more”.  I find that amusingly ironic.  The same desires my dad has for me have made their way into the PCB Industry.  As designers have sought to develop longer lasting and more complex electronics, circuit boards have been forced into a regimen of balancing traditional rigidity with the ability to bend, twist, and essentially be …
