Abstract:
The invention concerns a method for printing of a conductive coating on an electronic unit (22) by means of tampon printing. During the tampon printing phase a tampon pad (1, 15) is moving in small movements in one or more directions in relation to the electronic unit. The movements are made at the same time as the tampon pad (1, 15) is in contact with the surface to be printed.
Abstract:
A slanted connector and a method for mounting the same, having first connector means (20) extended in a first direction and second connector means (29a-c) extended in a slanted direction in relation to the first connector means (20).According to the invention the slanted connector comprises a first part (2) comprising the first connector means (20) and a second part (21a-e) comprising the second connector means (29a-c). The second part (21a-e) is connectable to the first connector means (20) and has a bent form in order to engage the first connector means (20) in a first direction and provide the second connector means (29a-c) protruding in at least one second direction slanted to the first direction, the second part (21a-e) having a circuit pattern to connect the first connector means (20) to the second connector means (29a-c).
Abstract:
A substrate (S) with at least two metallized polymer bumps (PS), especially a polymer stud grid array, is configured in such a way that the polymer bumps (PS) have at least one step (ST) and at least one elevation (E). The geometry of the solder bumps (PS) ensures that the soldered connections to the wiring (V) are secure and guarantees reproducible layer thickness for the solder (L).
Abstract:
An electrical junction box has a first insulating polymeric portion and a second polymeric portion defining multiple electrically conductive circuits. The circuits are at least partially separated by the first insulating polymeric portion and at least some of the circuits electrically connect together wire harness connector portions. A further aspect of the present invention junction box causes a section of the first insulating polymeric portion to concurrently act as a segment of an outer protective cover for the junction box.
Abstract:
The invention relates to an electrically conductive unit (1) extending by means of electrically conductive paths (10, 29), which are directly or indirectly applied onto a case (2), for creating a screening against electromagnetic radiation and/or for the draining of electrical currents.
Abstract:
Metallization is initially applied to a support to form metal conductor models with solderable and/or bondable connection areas (CA1, LA1) on electrically insulating supports (U1) and subsequently removed at least from areas adjacent to the desired conductor model. Galvanic deposition of a solderable and/or bondable terminal surface (E) on the connection areas (CA1; LA1) is conducted thereafter. The method does not require clean rooms.
Abstract:
A three-dimensional multi-layer moulded electronic device and method for manufacturing same, wherein the device comprises at least two moulded, three-dimensional substrates (12, 14) having mating surfaces (20, 22), each substrate including a layer (16, 18) of patterned conductive material on at least one surface and electrically conductive vias (24, 26) at selected locations of the substrate for interconnection of the conductive layers (16, 18), wherein the substrates (20, 22) are electrically joined at their mating surfaces and the circuit layers (16, 18) are aligned and interconnected to form a multi-layer, three-dimensional circuit which may include moulded-in structural features.
Abstract:
The present invention comprises an electrical contact (84) having solid homogeneous conductive particles on the contact (84) surface. The particles are of greater hardness than that of the contact (84) material to deform the contact (84) material and cause breakage or fracture of the oxide or other contaminating layer, or to penetrate the contaminating layer. The particles are applied to the contact (84) surface by a technique which results in the particles being intimately bonded to the contact (84) surface, usually as a layer of particles. A preferable technique for such particle application is hypervelocity oxygen fuel spraying (HVOF) or plasma spraying, by which the particles are embedded on the contact (84) surfaces to provide a substantially permanent interparticle bond between the applied particles and the contact (84) material.
Abstract:
A process for selective metalization for electrically isolating areas of a substrate (40) is disclosed. The process employs placing microridges (60) onto a surface (42), the microridge (60) protruding from the plane formed by the surface (42). The surface (42), including the microridge (60), is then metalized (66) and a portion of the metalized microridge (60) beyond the surface plane (42) is removed. This removal process creates electrically isolated areas (68) without affecting the integrity of the substrate (40).
Abstract:
This invention pertains to housings for electronic devices, and more particularly, to a molded housing for a radio receiver. Typical prior art housings require a large number of individual parts, and the variety of manufacturing processes and materials necessary to manufacture these parts elevates manufacturing costs. To reduce the total number of individual parts, the present invention comprises a molded thermoplastic housing (100) including a base (102) and cover (104) members joined by a living hinge (106). Solderable printed circuit patterns (112, 114, 116 and 118) are vacuum deposited onto the interior and exterior surfaces of both housing members. The printed circuit patterns on opposing surfaces of the base and cover members are joined by conductive through-holes (120 and 122). The printed circuit patterns on the interior surfaces of the base and cover members are joined by an interconnecting printed circuit pattern (124) which is vacuum deposited onto the living hinge.
