Abstract

An apparatus and method for extending the durability and life span of flexible circuitry by limiting the bend radius of the flexible circuitry and distributing the flexure point about an extended portion of the circuitry. The assembly includes one or more flex-limiting members associated with and integrated between the layers of flexible circuitry laminate. A fastener is affixed to the flexible circuitry laminate, operatively coupling the one or more flex-limiting members in position adjacent the flexible circuitry laminate. The flex-limiting member limits flexure of the circuitry, during each individual bend, to or below a predetermined angle, thereby decreasing the rate of failure in the circuitry, for example via short circuit, as a result of repeated or excessive bending.
