Abstract:
According to the present invention, a rearview mirror comprises a first substrate (12) having a front surface (12a) and a rear surface (12b), a reflective coating (15) disposed on a surface of the first substrate (12), and an electronic circuit component (24) secured to the rear surface (12b) of the first substrate (12). The mirror element may be an electrochromic mirror element comprising a transparent second substrate positioned in front of the first substrate. The electronic component secured to the rear surface may be a component of a drive circuit for the electrochromic mirror element. The rearview mirror element may further comprise electrically conductive tracings (150a, 150b) provided on the rear surface of the first substrate electrically coupled to the electrical component. The tracings (150a, 150b) is used to electrically couple the drive circuit to the electrodes of the electrochromic mirror element. The tracings is deposited on the rear surface using numerous methods including inkjet printing techniques.

Abstract:
According to the inventive method for producing planar contact surfaces for an SMD component, the connecting legs (2, 2') of said SMD component are first bent into a plane, as far as a bend tolerance value (PB) of approximately 100 mu m. The bent ends (20, 20') of the connecting legs (2, 2') are then coated with a conductive adhesive (3, 3'). In a subsequent step, said conductive adhesive (3, 3') is made level, for example by shearing with a rapidly rotating blade (6). After this leveling process, the conductive adhesive (3, 3') is hardened. The leveled surfaces (30, 30') of the conductive adhesive (3, 3') form contact surfaces with a planarity of less than 50 mu m, preferably less than 40 mu m. The SMD components with the inventive contact surfaces are particularly suitable for assembling according to the fine pitch bonding technique since they can be completely bonded with the thin layer of adhesive usually used in the fine pitch bonding technique as a result of their improved planarity.
Abstract:
An opto-electronic element (1) is mounted on a substrate (2) comprising an electric circuit (3, 3') with an electrically conducting layer (4, 4'). The opto-electronic element (1) has a body (5) for emitting light in a pre-selected wavelength range and is provided with current conductors (7, 7') which contact the conducting layer (4, 4'). According to the invention, an adhesive material (8) is used to mount to opto-electronic element (1) on the substrate (2) with clearance with respect to the substrate (2), the body (5) contacting the substrate (2) via the adhesive material (8). Preferably, the adhesive material (8) is a heat-conducting material which serves to cool the body (5) during operation. In order to make a reliable interconnection, the geometry of the current conductors (7, 7') is optimized in such a way that a small tensile force (order of magnitude 1 N) is present in a weld between the current conductors (7, 7') and the conducting layer (4, 4'). The tensile force ensures that the opto-electronic element (1) is pressed into the adhesive material (8). The small tensile force is obtained by calibrating the current conductor (7, 7') during a "press" step in the laser-welding process.
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:
A stacked packaging assembly for a plurality of integrated circuit devices (76) employs a web (61) of flexible interconnect material folded into a 'layered' arrangement of parallel web fingers (61) onto which a plurality of integrated circuit devices (76) are surface-mounted. The leads (71, 73) of the integrated circuit devices (76) are attached to interconnect links (81, 83) of the flexible interconnect web (61). A plurality of heat sink plates (115) are interleaved with the folded web fingers (61) of the stack, as so to engage the integrated circuit devices (76) mounted on the web fingers (61). The heat sink plates (115) are retained by thermally conductive spacer blocks (131, 133) along their edges. The spacer blocks (131, 133) are clamped together in a compact laminate structure, so as to form a rigid support which relieves mechanical stresses at the folds of the web fingers (61).
