Abstract:
The preferred embodiment apparatus employs an interior trim panel (23) and an electrical harness (25) for use in an automative vehicle. In one aspect of the present invention, the interior trim panel has a generally rigid substrate (27) covered by an aesthetically pleasing covering material (29). In another aspect of the present invention, an electrical harness (25) is provided with integrally created switch contacts (71; 73; 91; 101) and integrally created connector terminals (271). The invention includes an electrical harness (25) made by injection molding a catalytic platable polymeric resin (41) in a first injection mold. Next, a second shot of a non-catalytic polymeric resin (43) is injection molded over portions of the catalytic platable polymeric resin (41) in a second mold. The surfaces of catalytic platable polymeric resin (41) which remain exposed after overmolding of non-catalytic polymeric resin (43) define multiple circuits (45). An adhesion promoter is applied to these exposed circuit areas and then these exposed surfaces are plated with an electroless copper which is attracted to the catalyst in catalytic platable resin (41). The polymeric resins are preferably selected from those having a relatively high heat deflection temperature. The non-catalytic polymeric resin (43) acts as an insulator while the raised and plated portions of catalytic platable polymeric resin (41) act as electricity carrying, conductive circuits or traces (45).
Abstract:
A method for forming a self-limiting, silicon based interconnect for making temporary electrical contact with bond pads on a semiconductor die is provided. The interconnect includes a silicon substrate having an array of contact members adapted to contact the bond pads on the die for test purposes (e.g., burn-in testing). The interconnect is fabricated by: forming the contact members on the substrate; forming a conductive layer on the tip of the contact members; and then forming conductive traces to the conductive layer. The conductive layer is formed by depositing a silicon containing layer (e.g., polysilicon, amorphous silicon) and a metal layer (e.g., titanium, tungsten, platinum) on the substrate and contact members. These layers are reacted to form a silicide. The unreacted metal and silicon containing layer are then etched selective to the conductive layer which remains on the tip of the contact members. Conductive traces are then formed in contact with the conductive layer using a suitable metallization process. Bond wires are attached to the conductive traces and may be attached to external test circuitry. Alternately, another conductive path such as external contacts (e.g., slide contacts) may provide a conductive path between the conductive traces and external circuitry. The conductive layer, conductive traces and bond wires provide a low resistivity conductive path from the tips of the contact members to external test circuitry.
Abstract:
The invention concerns a method for producing electronic modules with ball connector (7) or integrated preforms capable of being soldered on a printed circuit (3) and a device for implementing said method. The invention concerns a method for producing electronic modules in the form of ball housings combining a ball grid array (7) or geometrically identical preforms for interconnecting or shielding and surface-mounted components (2) on the same surface of a substrate (1), thereby enabling said module to be directly connectable by soldering on a printed circuit (3). The balls (7) and the components (2) are transferred in one single step onto the substrate (1) by means of a gripping device adapted to the topography of the module to be produced.

Abstract:
A right angle electrical connector (10, 66, 70) that uses straight contacts (22, 82, 98), rather than contacts bent at a right angle. A flat insulative plate (30, 115) extends rearwardly from a tall portion of the connector body device (12, 77, 91) that is mounted over a printed circuit board (14, 110, 110'). Pegs (40, 120) formed on the bottom of the plate are mounted over a printed circuit board (38, 124, 126) in the printed circuit board. Conductive traces (44, 46, 43, 50, 128, 134) extend from contact passages in the connector body to the flat plate and pegs to provide electrical connections between contacts mounted in the passages and the printed circuit board.

The invention relates to a method for producing interconnections with electrically conductive cross connections between the top and the bottom part of a substrate and interconnections having such cross connections. The substrate (S1) is given a slanted, roof-shaped or convex contour (K1) in the area of at least one front face and/or in the area of at least one inner wall of a recess. After metallizing the substrate (S1), printed-board conductor-shaped cross connections (Q) are produced in the area of the above-mentioned contours (K1) simultaneously with laser structuring of printed board conductors (L) on the top part (O) and the bottom part (U) of the substrate (S1).
