Flex film card edge connector and cable assembly

A method of making a cable assembly, comprising the steps of:

• providing a length of flexible film having a mid-portion comprising a first set of conductive pads side-by-side with a second set of conductive pads, a first set of circuit traces on the flexible film arranged in a U-shape and connecting a first portion of the first set of conductive pads to a first portion of the second set of conductive pads, and a second set of circuit traces on the flexible film arranged in a U-shape and connecting a second portion of the first set of conductive pads to a second portion of the second set of conductive pads;
• providing a substrate having opposite major surfaces joined by an edge;
• wrapping the flexible film around the edge of the substrate such that both the first portion of the first set of conductive pads and the first portion of the second set of conductive pads are disposed on one of the major surfaces of the substrate, and both the second portion of the first set of conductive pads and the second portion of the second set of conductive pads are disposed on the other major surface of the substrate;
• severing the substrate and the flexible film in an area between the first and second sets of conductive pads, thereby forming first and second connectors;
• and
• separating the first and second connectors from each other, thereby forming a cable assembly having the first connector at one end and the second connector at an opposite end.
