Title: Flip chip package mounting
Inventor: TOKUDA SATOSHI
IPC: H01L21/60
Filed: 1990-04-27
Abstract: PURPOSE:To improve the accuracy of a mutual position of a chip with respect to a board by sandwiching an insulating plate between an IC chip and its packaging board in such a way that each through hole is made at the position corresponding a part where the above chip is connected to the packaging board. CONSTITUTION:A spacer 4 is placed on a board 2 in such a way that each through hole 4a is located at a part where a chip is connected to the board 2 and further, an IC chip 1 is placed on the spacer 4 in such a way that each solder bump 3 is located at the through hole 4a corresponding to its solder bump 3. Then reflow of solder bump 3...3 are performed. Reflow makes solder flow to the lower side of the through hole 4a and then, conductor patterns 2a...2a on the surface of the board 2 get wet with solder. Under such a condition, simultaneously with electric connection of the IC chip 1 to the board 2, they are fixed by making solder become hard. Further, a packaging construction is obtained by potting liquid resins 5 at the periphery of the IC chip 1. Even though forms of the solder bumps 3...3 that are formed at the IC chip 1 are uneven the inclination of the IC chip 1 is prevented when packaged because the IC chip is held in parallel to the board 2 by the spacer 4 on the occasion of performing reflow.

Filed: 1998-04-24
Abstract: PROBLEM TO BE SOLVED: To obtain a factory test method in which the cost of a factory test can be reduced by a method wherein, regarding only one representative pump, a pump performance test is made by a substitute low-temperature liquid and only a rotation confirmation test in a gas is made to other pumps so as to omit their pump performance test. SOLUTION: As a method for the rotation confirmation test in a gas of a pump for a liquefied gas, a pipe 20 which is used to supply a high-pressure gas at a proper pressure from the outside is connected to the entrance part 12' or the like of a liquid- supply flow passage 12 or the like at a static-pressure bearing 5E or the like. The high-pressure gas to be supplied is passed through the pipe 20, it is then passed through the liquid-supply flow passage 12, and it is spouted from the static-pressure bearing 5E so as to support a pump shaft 5A. In this manner, the high-pressure gas at the proper pressure is supplied to the static-pressure bearing 5F from the pipe 20. Therefore, since the pump shaft 5A is turned in a noncontact state with the static-pressure bearing 5E or the like, the sliding abrasion of the static-pressure bearing 5E or the like is not generated.  Irrespective of a material for the static-pressure bearing 5E or the like, the rotation confirmation test of the pump, for the liquefied gas, comprising the static-pressure bearing 5E can be made safely.
