    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.

    摘要： A method for making and repairing connections between first and second circuits, such as flex circuits. An article 10 includes: a flexible dielectric substrate 12 having first and second edges 14/16, and a plurality of conductive circuit traces 18 arranged on or within the substrate, wherein each of the traces extends from proximate the first edge 14 to proximate the second edge 16. Each of the circuit traces 18 includes: a first connection feature 20 disposed proximate the first edge 14; a second connection feature 22 disposed proximate the second edge 16; and at least one third connection feature 24 disposed between the first and second edges 14/16. Each of the first, second, and third connection features 20/22/24 is a plated through hole, a plated blind via, or a mounting pad. This article 10 may be used to connect together the first and second circuits 50/60 using the first and second connection features 20/22, such as by soldering. If either of the two circuits needs to be subsequently detached (e.g., because of a component failure), the article 10 may be cut so as to present a set of third connection features 24 to which a new replacement circuit may be connected.

    摘要： A novel apparatus for compressing viscous material through openings in a stencil is disclosed. The novel apparatus has a compression headcap which provides a contained environment to direct and to aid the flow of pressurized viscous material through the openings in the stencil. The compression headcap includes two generally parallel wiper blades that are biased into sliding communication with the stencil. Longitudinal diffuser plates guide and equalize the flow of the viscous material into the volume between two generally parallel wiper blades.
