An assembly (5) 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. An assembly (5) comprises one or more flex limiting members (10, 20, 30, 40) associated with and integrated between the layers of flexible circuitry laminate. A fastener (60) is affixed to the flexible circuitry laminate, operatively coupling the one or more flex-limiting members (10, 20, 30, 40) in position adjacent the flexible circuitry laminate. The flex-limiting member (10, 20, 30, 40) 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.
Ensemble (5) et procédé permettant de prolonger la durabilité et la durée de vie d'un circuit souple en limitant le rayon d'incurvation dudit circuit et en répartissant le point de flexion sur une partie agrandie du circuit. Cet ensemble (5) comporte un ou plusieurs éléments limitant la flexion (10, 20, 30, 40) associés aux couches du circuit stratifié souple et introduits entre lesdites couches. Un dispositif de fixation (60) est fixé sur le circuit stratifié, et couple de manière opérationnelle les éléments limitant la flexion (10, 20, 30, 40) dans une position adjacente au circuit stratifié. L'élément limitant la flexion (10, 20, 30, 40) limite la flexion du circuit, pendant chaque incurvation individuelle, jusqu'à un angle prédéterminé ou moins, ce qui réduit le taux de défaillances du circuit, telles que les courts-circuits, résultant d'une incurvation répétée ou excessive.
