    摘要: A method of manufacturing an electronic circuit assembly that includes a number of electrically interconnected flexible films, each flexible film having a flexible electrical wiring circuit. The electrical wiring circuits are interconnected between film layers and the film layers are adhered to a molded backing structure. A first flexible film is formed with a pattern of flexible electrical wiring circuits created on at least one surface thereof. The first flexible film has a passage that provides an electrical connection through the flexible film. A second flexible film is formed with a pattern of flexible electrical wiring circuits created on a least one surface thereof. The second flexible film has an electrical interconnect feature that connects with the electrical passage on the first film and electrically connects the first film with the second film. The first flexible film is overlaid juxtaposed the second flexible film so that the passage is aligned adjacent the electrical interconnect feature. The first and second flexible films are placed within an open mold. The mold is closed and a plastic material is injected within the mold adjacent at least one surface of the first and second flexible films. The molten plastic adheres to the first and second flexible films and forms an integral backing structure. The backing structure and first and second flexible films together form the circuit assembly.

    摘要: Method of manufacturing a multi-layer printed circuit board adapted for reduce interfacial sheer stresses includes a laminate substrate having a top layer forming a first major surface, a middle layer having a predetermined thickness and a bottom layer forming a second major surface opposed to the first major surface. Etch resists are disposed on the first and second surfaces corresponding to reverse images of desired conductor patterns. The first and second surfaces are thereafter etched and the photoresist removed. The laminate substrate is secured via a low modules adhesive layer to a major surface of a base. The middle layer of the laminate substrate is thereafter selectively etched so as to isolate selected portions of the first and second surfaces and to define inner connect regions therebetween having a height equal to the predetermined thickness.

    摘要: An electronic assembly includes a flexible multilayer substrate having integral electrically-conductive traces that also includes, as a lowermost layer, a metal foil. A plurality of uppermost layers, likewise including a metal foil, form a thin barrier member that is sealingly attached to the substrate's other layers. In this manner, a plurality of electronic components, mounted on the substrate's other layers so as to be electrically interconnected with the traces before sealingly attaching the barrier member, are encapsulated within metal foil to provide an environmentally-sealed assembly featuring improved resistance to moisture diffusion and penetration/permeation of other substances characteristic of the assembly's service environment into the assembly. A filler material, also encapsulated within the metal foil, is operative to neutralize a predetermined amount of a penetrant, further improving the operability and service life of the assembly. Preferably, a relatively-rigid polymeric material is formed in touching contact with the substrate, as by overmolding the plastic material on the environmentally-sealed assembly, to thereby provide a plastic part incorporating the assembly.
