Abstract:
PROBLEM TO BE SOLVED: To provide a chip part mounting body wherein the occurrence of short circuits is suppressed between a neighboring pad and chip when the amount of the conductive adhesive is increased and the area of contact of the conductive adhesive with the chip is enlarged, and to provide a semiconductor device. SOLUTION: In this chip mounting body, a chip 2 is mounted on a printed circuit board 1 with a conductive adhesive 3 in-between. The chip 2 has a corner 2b, and the ridgeline of the corner 2b is arranged to face the pad 1a of the printed circuit board 1. The chip 2 is mounted on the pad 1a so that acute angles α are formed between the faces of the chip 2 neighboring the ridgeline of the corner 2b and the surface of the pad 1a.

Abstract:
PROBLEM TO BE SOLVED: To provide a current-switching circuit device and a circuit device for electric power steering with little heat generation, and small wiring impedances at a lead part of a switching element. SOLUTION: This circuit device is provided with a printed board 61 mounting various circuit elements; and a housing 81 as a heat sink, having a switching element mounting part 82 formed an inclined surface 82a with the distance with the printed board 61 being gradually extended. Switching transistors 31 to 34 are arranged on the inclined surface 82a of the mounting part 82, while arranging leads 31b to 34b toward the side close to the printed board 61. Main bodies 31a to 34a are fixed on the inclined surface 82a in an almost close contact state. The leads 31b to 34b are connected directly and electrically to the printed board 61.

Abstract:
PROBLEM TO BE SOLVED: To provide a simple structure for a holder 3 and to reduce the unmountable area of other components, in a mounting structure of an SFP module 4 made so as to keep the SFP module 4 connected to a connector 2 mounted on a PT board 1 with the holder 3. SOLUTION: The holder 3 includes both side surfaces 3a supporting the SFP module 4 on both sides, turn-back parts 3b provided to the upper edge of each side surface 3a, enabling the SFP module 4 to be inserted and pulled off in an oblique direction and preventing the SFP module 4 from coming off upwardly, and a bottom surface 3c fixing the both side surfaces 3a on the PT board 1. The connector 2 is equipped with an electrode, having return elastic force capable of keeping the SFP module 4 inserted into the holder 3 from an oblique upward direction and turning the SFP module 4 up to a state that is parallel with the PT board 1.
