ABSTRACT:
A flexible circuit assembly and a method of making it in which there are no separate electrical interconnections between the flexible interconnecting cable and the rigid connector. A flexible insulating film is bonded to a surface of the connector member and extends from the connector to provide a flexible interconnecting cable for external electrical connections. A plurality of conductors on the insulating film provides a continuous electrically conductive path thus providing an interfaceless electrical connection between the rigid connector and the flexible interconnecting cable. In the method, a metallic clad insulating film is placed on a surface of a rigid support member which includes a portion which will serve as the connector. The support member also includes a filler block portion in the space designated for the flexible interconnecting cable. The film is selectively bonded to the connector portion of the support member. Conductors are then formed on the insulating film. The filler block is then removed to leave a rigid connector and a flexible interconnecting cable which has a plurality of continuous conductors thereon thereby eliminating a separate electrical connection therebetween.
