摘要:
The present invention reduces the occurrence of fracture in external terminal connecting sections and improves the reliability of secondary packaging of a semiconductor device. Specifically, the present invention provides a semiconductor device including a wiring board, a semiconductor chip mounted on one surface of the wiring board via a bonding member, and external electrodes formed on the other surface of the wiring board and electrically connected to the semiconductor chip. In the semiconductor device, a peripheral end of the bonding member is arranged in a position where the peripheral end does not overlap the external electrodes.

A compact vehicle production line. The production line comprises a floor process of assembling floor constituent parts. Each is an aluminum alloy extrusion die cast product, which has been made, in an extrusion die casting process, by forcing molten aluminum alloy through a mold cavity in a predetermined direction. The assembled floor constituent parts are welded to make a floor structure. In an interior parts mount process, interior parts are to the floor structure to make a floor unit. In a body main process, each of two body side structures are trimmed to make a body side unit. A roof structure is trimmed to make a roof unit. The floor unit, the body side units, and the roof unit are assembled. The assembly is welded to make a body unit. In a running parts mount process, an under running unit is mounted to the body unit. In an exterior parts attachment process, color body panels are attached to the body unit.

A method for manufacturing a multilayer laminate provides in metal plates each forming a substrate apertures at positions where through holes are to be formed, fills the apertures with a synthetic resin including a first filler, and prepares prepregs to be disposed on both sides of each substrate by impregnating nonwoven fabric with a thermosetting synthetic resin containing a second filler. The metal plates forming the substrates are thereby allowed to be thicker for realizing larger capacity power supply with an improvement also in heat dissipation characteristics.
