Abstract:
An electronic device includes a printed circuit board having lands and an electronic element having a body and terminals. First and second lands provide a zigzag pattern. Each first land is coupled with the first terminal, and each second land is coupled with the second terminal. The second terminal includes a first parallel member, a first connection member, a second parallel member and a first mounting member. The first parallel member is completely embedded in the body, or another part of the first parallel member exposed from the body is shorter than the second parallel member. A second height between the second parallel member and the printed circuit board is smaller than a first height between the first parallel member and the printed circuit board.
Abstract:
A method is described for producing an electrical connection between a plug element and a printed circuit board. A plug end of the at least one plug element is inserted in an opening extending through the printed circuit board. A solder, preferably in the form of solder paste, is applied essentially from above to at least parts of the opening or the area surrounding the opening. The connection between the board and the plug end is achieved by melting the solder. Prior to melting of the solder and/or application of the solder, the plug end is introduced into the opening in the printed circuit board essentially from below, and is held therein by a retaining arrangement such that during melting the solder enters the opening from above and contacts the plug end.
Abstract:
A printed circuit board is disclosed which comprises a plurality of non-through holes into thickness direction in one surface of the board, a plurality of through holes in some of the non-through holes to open through opposite surface of the board and having a smaller inside diameter than the non-through holes, a plurality of first conductive lands on the periphery of the openings of the non-through holes in one surface of the board, a plurality of second conductive lands on the periphery of the openings in opposite surface of the through holes and having the smaller outside diameter than the second lands on the periphery of the openings of the non-through holes, a conductor layer in inside wall of the non-through holes and the through holes for connecting the first lands in one surface and the second conductive lands in opposite surface of board, and conductive patterns formed in one surface and opposite surface of the board respectively, which invention is capable of including the great number of the conductive patterns as necessary for mounting the electric component such as PGA or HPC without multilayering the board or going around of the conductive patterns, because of the greater number of the spaces between the second lands can be formed in opposite surface.

Assembly workability of an electric compressor to which an inverter circuit section and a filter circuit section are attached is improved. The inverter circuit section (3) includes an inverter control board (17), a sleeve assembly (18), and a power module (14). The inverter control board, the sleeve assembly, and the power module are integrated. The filter circuit section (4) includes a filter circuit board (66) and a support member (67). The filter circuit board (66) and the support member (67) are integrated. The inverter circuit section and the filter circuit section are structured to be capable of being stored each individually within an inverter storing section (8) from the same direction and detachably attached to the housing (2).
Abstract:
An electrical assembly, such as a multi-layer bus bar, includes an electrical connection pin and a plurality of electrically conductive layers. Each of the electrically conductive layers is formed to define a cutout therein to receive the electrical connection pin and allow access for joining material to join the electrical connection pin with the plurality of electrically conductive layers. Each of the cutouts is formed to include a first portion arranged around the electrical connection pin and a second portion located radially outward of the first portion.
Abstract:
According to exemplary embodiments, a tapered surface interconnect is formed on a printed circuit board (PCB). A compliant pin of an electrical connector may be coupled to the tapered surface interconnect and soldered thereto. The surface interconnect may be formed by drilling through one or more layers of the PCB. The depth of the surface interconnect may be shorter than a height or a thickness of the PCB. The surface interconnect may have a tapered side wall to allow for a better fit with a tapered compliant pin. The inclination of the side wall of the surface interconnect may be linear or concave. The intersection between the tapered sidewall and the bottom of the surface interconnect may be rounded to minimize pin insertion issues and may allow for easier solder flux evacuation. The compliant pin may be soldered into place upon being coupled to the tapered surface interconnect.
