Embodiments of a system to maintain an even temperature distribution across a laser detector are generally described herein. In some embodiments, the system includes a multi-layer printed circuit board (PCB) assembly that includes a first layer comprising a thermally-conductive ring provided circumferentially around a thermally-conductive detector region for mounting the laser detector, a second layer comprising a plurality of resistive elements aligned with the thermally-conductive detector region to generate heat, and a fourth layer comprising a thermally-conductive heat-distribution region aligned with the thermally-conductive detector region. A plurality of thermally-conductive vias is provided to couple the thermally-conductive ring of the first layer to the thermally-conductive heat-distribution region of the fourth layer. The thermally-conductive vias transfer heat between the thermally-conductive heat-distribution region and the thermally-conductive ring to provide an even distribution of heat across the laser detector.

Die Erfindung betrifft eine Vorrichtung zum Auflöten eines elektrischen Leiters auf eine Metallisierung eins Schaltungsträgers. Unter einem Schaltungsträger wird insbesondere eine Solarzelle verstanden. Um auf der Metallisierung einer solchen Solarzelle einen elektrischen Leiter aufzulöten, wird eine Vorrichtung vorgeschlagen, bei der zwei Kontaktelemente vorhanden sind, die beidseits der Auflötstelle des elektrischen Leiters angeordnet sind und über die ein elektrischer Heizstrom durch den elektrischen Leiter zu führen ist, wodurch dieser so erhitzt wird, dass er anzulöten ist. Die Vorrichtung weist dabei Niederhalter auf, um den elektrischen Leiter an die Solarzelle zu drücken und somit eine sichere Verlötung zu bewirken.

The ignition trace (10) includes an ignition pad (11) disposed on the printed circuit board (19) adjacent to, but electrically isolated from, a bond pad (12) in the bonding region on the printed circuit board (19), a remote pad (13) disposed outside the bonding region on the printed circuit board (19) to which an electrode (16) may be electrically connected for delivering an initiating electrical current, and a trace (18) connecting the remote pad (13) and the ignition pad (11). The trace (18) is configured to conduct an initiating electrical current from the remote pad (13) to the ignition pad (11) and into any adjacent reactive multilayer foil performs (14) in electrical contact with the ignition pad (11) in the bonding region.
摘要:
This invention concerns a process for establishing at least one electrically conducting connection between two or more conductor structures (2, 4), of which at least one is connected to a carrier (3) to form a conductor compound system. At least one of the conductor compound systems has openings (6) at the points of contact of the conductor structure in the region of which the connection is established by supplying thermal energy or by introducing an electrically conducting material. The invention makes it possible to establish electrically conducting connections between several conductor structures in a simple and cost-efficient manner and avoids damage even to temperature-sensitive thermoplastic carriers.
摘要:
Systems and methods for etching topographic features in non- crystalline or metallic substrates are provided. A protective material is placed and patterned on a surface of the substrate to define exposed and protected regions of the substrate for etching in a liquid etchant having etching rates that are thermally activated. A nonuniform temperature profile is imposed on the substrate so that the temperatures and hence the etching rates at surfaces in the exposed regions are higher than those in the protected regions. Arrangements for imposing the nonuniform temperature profile include heating designated portions of the substrate with light radiation. Alternatively, the non-uniform temperature profile is developed as etching progresses by passing current pulses through the substrate in a manner that causes geometrically non-uniform heating of the substrate.
