Patent JP-H11126795-A (JP)
Title: Mounting board and manufacture thereof and mounting method of electronic component
Inventor: MATSUO TOSHIKAZU
IPC: H05K3/24
Filed: 1997-10-23
Abstract: PROBLEM TO BE SOLVED: To prevent an occurrence of cracks caused by the thermal stress generated by the bonding of a solder ball to a land, by providing the constitution wherein the side surface is surrounded without gaps at the specified height by solder resist and the solder ball having the fixed land can cover the entire side surface of the protruded land. SOLUTION: At the back surface of a back-surface bonding type electronic part 6 such as BAG.CSP, a solder ball 7 connecting the electronic part 6 and a land 8 is formed. The diameter of the land 8 is made smaller than the diameter of the solder ball 7 so that the entire land 8 is covered by the solder ball 7 when the land 8 and the solder ball 7 are bonded. Since the boundary part of the land 8 and the solder ball 7 is formed at the side surface of the land 8 vertically extending for the surface of a base material 2, the interface angle between the solder ball 7 and the land 8 becomes the obtuse angle not only at an interface angle α of a boundary part A in the wiring direction but also at an interface angle βof an wiring-direction interface part B. The interface angles become the abtuse angles at all places.

Inventor: ODAKA AKIHIRO
IPC: H03K17/687
Filed: 1999-10-13
Abstract: PROBLEM TO BE SOLVED: To reduce a spike voltage, and to shorten a spike voltage reducing period or the like. SOLUTION: Inverse series circuit of Zener diodes ZD1 and ZD2 and diodes D1 and D2 (clamp circuit: a spike voltage suppressing circuit in a figure) are connected between gates/collectors G1.C1 and G2.C2 of each transistor of a semiconductor bi-directional switch SW in which the transistors are connected in inverse series or inverse parallel. Thus, a spike voltage to be generated in both directions in the semiconductor bi-directional switch SW can be suppressed only by a smaller element than that in a conventional manner with which a snubber circuit constituted of a resistance and a capacitor is connected.

Title: Semiconductor device
Inventor: TAKADA KEISUKE
IPC: H01L23/29
Filed: 1985-12-25
Abstract: PURPOSE:To obtain a semiconductor device which reduces the heat absorption of a package of an IC without increasing working steps by forming a character and numerals on the surface of the package and simultaneously forming a heat shield. CONSTITUTION:Character A and numerals which represent the type of an IC 11 are formed by silver ink on the upper surface of the package 22 of an IC 21. A part 23 of a resin material of the package 22 is formed at a desired interval with a heat shield 24. Projections 31a, 31b of a rubber seal 31 form part of numerals 2 and 3, and a projection 31c forms a heat shield 24. The seal 31 is pressed on the package 22 to simultaneously form a character, numerals and a thin film to become the heat shield 24 on the package 22 with silver ink. That is, the step of forming the heat shield 23 is not necessary. Since most of the package 22 is covered with the ink having heat reflecting property, the heat absorption of the package 22 is reduced.

Title: Production of fiber reinforced metallic parts
Inventor: SASAKI MASAYOSHI
IPC: B22D19/14
Filed: 1988-11-17
Abstract: PURPOSE:To prevent the generation of defects, such as blow holes by reducing the pressure in a cavity through the parting planes of the outer peripheral part, etc., of projecting pins. CONSTITUTION:Alumina silica fibers are first compressed to form a fiber molding 21 of, for example, a piston shape. The fiber molding 21, a pressurizing punch 13, a core 7, and a master mold 6 are respectively preheated to prescribed temps. The fiber molding 21 is so set in the master mold 6 as to be put on the core 7 in the state of pulling up the pressurizing punch 13. The melt 22 of an Al alloy adjusted to the prescribed temp. is immediately poured into the cavity 23 in the master mold 6 to cover the fiber molding 21. Gate valves 17, 18 are opened approximately simultaneously therewith and the pressure in a main post 3 is rapidly reduced by a vacuum tank 15 and a vacuum pump 16. Since the inside of the main post 3 is communicated with the respective parting planes 20 of segmental cores 7 and the parting planes 20 around projecting pin 10 to the front surface side of the cores 7, the gases in the fiber molding 21 are rapidly removed from the inner peripheral side thereof. The generation of blow holes and run defect by the defective degassing is thus obviated.
