摘要:
DIMMs to be cooled are mounted in DIMM areas of a printed circuit board of a system board. An air intake port that introduces cooling air is arranged on a side plate of the system board, whereas an air discharge port that discharges the cooling air is arranged on another side plate. The cooling air flows in a direction that is oblique with respect to the side plate. The air intake port is arranged at a position that is offset in the direction in which the cooling air is supplied. Accordingly, cooling is possible by efficiently bringing the cooling air into contact with the DIMMs.

An electronic part having mounting terminals made of a thermally-meltable bonding material is mounted on a mounting board. A structural part is used for moving a height-adjusting member to a position under the electronic part in a process of heating and melting the thermally-meltable bonding material so as to maintain a predetermined distance between the electronic part and the mounting board.

The spacer is formed as an elastic member with no ends thereof, which is detachably attached, by exploiting its elastic deformation, onto a printed wiring board to which is fixed an electronic component having a component package, on one of whose surfaces connection terminals are arranged. Since the spacer is attached on the printed wiring board to enclose an electronic component so as to seal a gap formed between the electronic component and a printed wiring board, it is possible to prevent foreign objects entering the gap, so that failures, such as insufficient insulation, caused by such foreign objects are also prevented. Since the spacer is easily removed from the printed wiring board, it is recyclable and economical.
摘要:
A printed board unit includes a printed board including lands thereon, a semiconductor device unit, and an attachment mechanism to attach the semiconductor device unit to the printed board. The semiconductor device unit includes a heat transfer member, a semiconductor device including first and second surfaces parallel to each other, the first surface having lands thereon, and a socket including contacts protruding from first and second surfaces of the socket, the first and second surfaces being parallel to each other. In the semiconductor device unit, the semiconductor device and the socket are attached to the heat transfer member so that the second surface of the semiconductor device opposes the heat transfer member. The lands of the semiconductor device are electrically connected to the lands of the printed board unit via the contacts of the socket.
摘要:
A bonded board is formed by bonding at least two boards via an insulation member. A through hole is formed in the bonded board to mount a firs electronic component on one face of the bonded board, and a second electronic component on the other face of the bonded board. The first electronic component and the second electronic component are electrically connected via the through hole.
