Abstract

A surface mountable flexible interconnect (10) for connecting two circuit board (30, 32) consists of a flex circuit (12) with solderable runners (14) on one side, the runners traversing the flex circuit from one end to the other. There is a solderable pad (16) at the end of each runner, and each solderable pad has a solder bump (18) fused to it. A rigid carrier ring (20) is used to hold the flex circuit in position prior to placement on the PCB. The flex circuit is formed into a U-shaped loop (26), and the loop is aligned to the carrier so that the loop is situated in an aperture (24) in the carrier. The solder pads lie directly under the carrier ring and face away from it. An adhesive (22) bonds the flex circuit to the carrier ring.
