摘要:
An electronic device of the present invention has a pair of joint pieces 2a, 2b formed on one end of its body and extending to both sides of the body. Both of these joint pieces 2a, 2b are connected to one substrates 5, 7 to improve the joining strength between a lead frame connector 1 and the substrate and ensure the reliability of electrical connection between the lead frame connector 1 and the substrate 5,7.

A power module comprises a heat radiation layer (13) having the first main surface and the second main surface of reverse side opposed to the first main surface, an insulation layer (12) disposed on the first main surface of a radiation layer, a wiring potion for current circuit (11) disposed on the insulation layer and a plurality of switching elements (10) disposed on the insulation layer and electrically connected to the wiring portion of current circuit. A plurality of external terminals (20) are electrically connected to the wiring portions of current circuit. Furthermore, the module has a resin (2) sealing all of the insulation layer, a wiring portion for current circuit, switching elements and the first main surface of the radiation layer, and a resin sealing a portion of the second main surface of the radiation layer with the resin.
摘要:
In a module, press-fit connection using a pin terminal (1) including a connection part (2) separated into two parts and a flat plane (2a) parallel to the lengthwise direction in the separation part and perpendicular to the separation direction of the pin terminal (1) is performed. A through-hole of a board is structured so that (1) an inner diameter of the through-hole at a middle part in the thickness direction of the board is smaller than that at obverse and reverse surfaces of the board (4) and (2) the length of the middle part of the through-hole connected to the pin terminal (1) is shorter than the length of the flat plane (2a) of the pin terminal (1).
