Flexible circuit board interconnect with strain relief
First Claim
1. A flexible circuit board connector, comprising:
- a flexible substrate;
at least one connector conductor strip disposed on a first side of said substrate;
a first soldermask layer disposed on said first side of said substrate over top of said at least one conductor strip;
wherein said soldermask layer has at least one scalloped edge.

Abstract
A flexible circuit board interconnect is provided with flex strain relief capabilities. The flexible circuit board interconnect includes a polyamide or polyimide (both are nylons) substrate layer, a ground plane layer and a conductor strip layer. The ground plane layer is provided with scalloped edges along opposite sides thereof. The ground plane provides a shield for preventing radio frequency interference to and from the signals passed through the conductor strips. The ground plane layer and the conductor strips are covered at least partially by a pair of soldermask layers which are provided with scalloped edges. The scalloped edges on the soldermask layers and the ground plane prevent the generation of a crease or fold line on the surface of the flexible circuit board interconnect. Each of the conductor strips are provided with a pair of vias on opposite ends of thereof. The vias are arranged to be offset from the vias on adjacent conductor strips such that a perforation-type tear line is avoided and such that when a hot bar soldering is used, at least one via remains uncovered for receiving soldering wicking, thus reducing the likelihood of solder bridging across conductor strips.
