Filed: 2001-04-09
Abstract: PROBLEM TO BE SOLVED: To optimize shape and direction of a pad and prolong a solder life when compared to a conventional device by making a deformation center between a semiconductor device and a substrate clear. SOLUTION: In a BGA-type semiconductor device which conductively connects and fixes a plurality of pads formed in the lower surface of a base whereon a semiconductor element is mounted and a substrate 20a by a solder ball 8, a restraint means 18 for restraining relative position relation between a BGA 1a and the substrate 20a is disposed almost at a center of opposite surfaces between a base and a substrate. The restraint means 18 can be thermosetting resin such as epoxy or a metal such as Cu, Fe-Ni, Al which is harder than solder.

Title: Plate fin type heat exchanger
Inventor: YOSHIDA HIROSHI
IPC: F28D1/053
Filed: 2001-04-11
Abstract: PROBLEM TO BE SOLVED: To prevent heat exchanging efficiency from lowering due to shifted flow in a plate fin type heat exchanger employing such an arrangement as the fluid passing area in a head tank is significantly narrower as compared with an ordinary heat exchanger because of reduction in size, or a shifted flow is generated easily due to various factors, e.g. the introducing and delivering directions of fluid are specified.
