Abstract:
The present invention discloses a USB application device including a body, a circuit board, a plurality of first electrical pins and a plurality of electrical elements. The circuit board is disposed in the body. The plurality of first electrical pins are disposed on the circuit board and expended to the body such that the plurality of first electrical pins are partly exposed to the body. A space is formed between the plurality of first electrical pins and circuit board such that the plurality of electrical elements can be disposed on the space. The length of the circuit board therefore becomes shorter, and the volume of the USB application device is reduced.
Abstract:
The invention relates to a method for producing a number of vias (6) in order to create electrically and/or thermally conductive connections between different faces (3, 4) of a substrate (1). The invention further relates to a substrate (1) comprising at least one via (6) that is produced in such a manner. The aim of the invention is to produce vias (6) in a particularly easy manner. This is achieved in that at least one electrically and/or thermally conductive foil (7) is inserted into a through-opening (8, 16) that connects different substrate faces (3, 4), and areas (9) of the at least one foil (7) are fixed near the edges (11) of the opening (8, 16) on the surfaces of the substrate faces (3, 4).
Abstract:
The circuit assembly has a substrate (4) with an electronic component (6). A metallic and electrically conductive strip (2) is arranged in a circuit pattern on the substrate. Connections (19) of the electronic component are electrically connected with contacting areas (8) of the conductive strip. Independent claims are also included for the following: (1) a method for creating a wiring pattern on a substrate; and (2) a device for creating a wiring pattern on a substrate.
Abstract:

Abstract:
A heat radiator (20) includes an insulating substrate (3) whose first side serves as a heat-generating-element-mounting side, and a heat sink (5) fixed to a second side of the insulating substrate. Two stress relaxation members (4) formed of a high-thermal-conduction material are disposed between the insulating substrate and the heat sink and include each a plate-like body (10) and a plurality of projections (11) formed on one side of the plate-like body. A side of the plate-like body of one stress relaxation member on which the projections are not formed is metal-bonded to the insulating substrate, whereas a side of the plate-like body of the other stress relaxation member on which the projections are not formed is metal-bonded to the heat sink. The projections of one stress relaxation member are positioned in respective gaps between the projections of the other stress relaxation member, and the end faces of the projections of one stress relaxation member being metal-bonded to the plate-like body of the other stress relaxation member, and vice versa.
Abstract:
A method for mounting terminal on circuit board includes an applying process for applying solder paste (3) to a desired circuit board (1), a laying process for laying the connecting ends (4a) of terminals (4) having the connecting ends (4a) and non-connecting ends (4b) on the parts coated with the paste (3), and a heating process for melting the paste (3) for soldering the connecting ends (4a) to the board (1). In the applying process, a plurality of sets of solder paste applying parts (3a-3d) which are separated from each other are provided on the board (1). In the laying process, each connecting end (4a) is laid across each set of parts (3a-3d).
