Title: Double-side printed board
Inventor: NUMAZAWA YOSHIHARU
IPC: H05K3/34
Filed: 1987-07-17
Abstract: PURPOSE:To eliminate silicon coating, and prevent short-circuiting between patterns, and the like caused by drops of water due to moisture condensation, by providing at least a single side with a printed layer, instead of the printed layer, wherein inverted characters of characters and parts symbols are formed on the whole surface of a substrate. CONSTITUTION:On a negative film, portions where characters 7 and parts symbols 8 are to be printed are printed. This negative film is inverted to form a positive film. By using this positive film, the following are formed; a surface pattern 2 formed on an insulating substrate 1, a soldering part 3, a through hole 5, and a printed layer 6 wherein the characters 7 and the parts symbols 8 are not printed. The formed printed layer 6 covers the whole surface of the substrate except the characters 7 and the parts symbols 8. Therefore, the metal part where moisture condensation is apt to occur, and in particular, the surface area of the soldering part 3 and solder 12 are reduced. Thereby, the moisture condensation becomes hard to occur. Further, the portion between terminals 11, and the gap between lines of the soldering part 3 are winded, so that short- circuiting due to drops of water becomes hard to occur.

Title: Manufacture of solid-state electrolytic capacitor
Inventor: NAITO KAZUMI
IPC: H01G9/00
Filed: 1987-07-20
Abstract: PURPOSE:To realize a high capacitance value with the small volume by a method wherein, after a positive electrode base substance having a dielectric oxide film has been brought into contact with a reaction mother liquid of a specific temperature range and has been left, it reacts with the mother liquid at a temperature of higher than a specific value so that the degree of impregnation of a semiconductor layer into the positive electrode base substance is increased. CONSTITUTION:The following are formed in succession on the surface of a positive electrode base substance composed of a metal having an action of a valve: a dielectric oxide film; a semiconductor layer which is manufactured by a chemical precipitation method and which is composed of lead dioxide or of lead dioxide and lead sulfate; a conductor layer. When the semiconductor layer is manufactured by the chemical precipitation method, the positive electrode base substance having the oxide film is immersed in a reaction mother liquid which has been formed by mixing a solution where a compound containing lead is dissolved with a solution where an oxidizing agent is dissolved. First, while the positive electrode base substance having the oxide film is brought into contact with the reaction mother liquid, it is left in a temperature range of higher than a solidifying temperature of the reaction mother liquid and less than 10 deg.C. Then, if the reaction mother liquid reacts at a temperature of higher than 28 deg.C, preferably at the temperature of higher than 28 deg.C and lower than 45 deg.C, the semiconductor layer is formed. By this setup, the semiconductor layer penetrates into a narrow hole of the positive electrode base substance; a surface area of the semiconductor layer is expanded; it is possible to manufacture a solid-state electrolytic capacitor having a large capacitance value even with the identical volume.

Abstract: PURPOSE:To quickly and easily execute a soldering operation between a solder bump and an FPC electrode by a method wherein the FPC is superposed on a part where an IC chip is positioned on a base plate and, while a pressure-contacted state by using a pressure plate is kept, a laser beam is irradiated to a soldering part only. CONSTITUTION:In a mask-attached glass sheet 20, a mask 22 is formed on the side of an FPC 1; an IC chip 4 is inserted into a recessed part 16 in a base plate of a jig; its solder bumps 9 are positioned in such a way that they protrude from the base plate; the FPC 1 is positioned on the bumps in such a way that conductor patterns 12 face the bumps 9. While a pressure plate 17 is positioned by using positioning pins 15 of the base plate 14, it is superposed on the FPC 1; a pressing force is exerted via the pressure plate 17. By keeping a state that the bumps 9 are pressure-contacted with the conductor patterns 12 in this manner, a laser beam 21 is irradiated downward from an upper part of a through window 19; soldering parts are irradiated with the laser beam 21 via light-transmitting windows 23 at the mask-attached glass sheet 20. Because the soldering parts are kept in a pressure-contacted state, the heat of the laser beam 21 is conducted to the bumps 9 effeciently; a satisfactory soldering operation can be executed.
