摘要: A process of batch assembly of sundry leaded or padded devices, encapsulated and non-encapsulated, onto a printed wiring board (PWB), which exhibit significant improvements in both manufacturability and reliability. A pressure frame assembly apparatus permits an application of uniformly distributed pressures to a variety of leaded packages and padded semiconductor chips during cure of conductive adhesives (AdCons), and leads to the reduction of variations in initial interconnection resistance, and thereby to the enhancement of the reliability of AdCon interconnections. The pressures are applied to the devices by an external application of a fluid under pressure to a flexible, resiliently stretchable membrane which conformably envelops outlines of the devices and adjacent areas of the PWB. Application of vacuum suction to within the cavity, formed by the pressure frame and the membrane, prior to the external application of the fluid pressure to the membrane, further improving the reliability of surface mounted assembly of packages on the interconnection board. The external application of pressure enhances thermal conductivity needed for curing the AdCon, increases the range of processing parameters usable for this technique and reduces assembly times. Assembly yields approaching 100% were observed for a variety of surface mounted packages indicating that the system will be highly reliable.

摘要: Magnetic circuit elements, e.g. for inclusion on circuit boards including one or more windings about a toroidal core are produced by joinder of mating sheets, one or both recessed to hold the core, and each containing partial windings. Joinder is by use of an anisotropically conducting adhesive layer. The layer is applied as an uncured thermosetting adhesive containing spherical conducting particles of such size and distribution as to statistically result in electrical completion of windings while avoiding turn-to-turn shorting.

摘要: Described is a novel packaging of MCM tiles without wire-bond interconnections and in a total thickness which is reduced relative to conventional MCM packaging. The MCM tile includes a substrate with a plurality of peripheral metallizations and at least one chip flip-chip mounted on the substrate. The PWB is provided with an aperture which is smaller than the size of the silicon substrate but larger than the outside dimensions of the mounted chips. The substrate is positioned on the PWB so that its ends overlap areas of the PWB adjacent the aperture and the chips fit into the aperture. Peripheral metallizations on the substrate are interconnected to metallizations on the PWB by either solder reflow technology or conductive adhesive technology.

摘要: Electrically conductive paths are produced on a polymeric substrate by laser writing, i.e., by tracing desired paths on the substrate by a laser beam. The resulting paths comprise electrically conductive carbon as produced by thermal decomposition of substrate surface material; the paths can serve; e.g., as electrical interconnections akin to printed circuitry on a wiring board. Optionally, the conductivity of paths can be enhanced by electroplating a suitable conductor metal or alloy onto the paths.
