Abstract: PROBLEM TO BE SOLVED: To form an extended solder bond between two electronic substrates which are mutually connected by the solder to form an electronic module, by heating the two substrates, imparting controlled separating force to the solder bond plasticized by the heat between the substrates, extending the solder bond, and refrigerating the resultant module to set the extended solder bond. SOLUTION: Solder bonds 12 having a height S are generally used for treating a printed circuit board or the like, i.e., a substrate 11, which is connected to a chip, i.e., a substrate 13. Specifically, the solder bonds 12 are formed between these two electronic substrates 11, 13 to form a mutually connected electronic module. Thereafter, the module is heated to plasticize the solder bonds 12. Subsequently, separating power is imparted to the two electronic substrates 11, 13 so as to extend the plasticized solder bonds 12, thereby forming an extended solder bond. Then, the module thus extended is refrigerated to complete the electronic module comprising the extended solder bond.

Abstract: PROBLEM TO BE SOLVED: To form an extended solder bond between two substrates which are mutually connected by solder to form an electronic module, by reflowing an extensible paste solder bump to extend an extension means thereof so as to raise the height of a first mutual solder connection, and forming an extended solder bond in the electronic module. SOLUTION: The distance between the upper surface of a substrate 19 and the lower surface of a substrate 16 which faces the substrate 19, is represented by C. A paste 17, which is formed on the substrate 19, is in receipt of the lower end of a reflowed solder ball 18 so as to be in contact therewith. The height of an extensible solder bump 14 is represented by B which is smaller than the height C of the solder ball 18. When the solder ball 18 is heated at a temperature high enough only to reflow itself, the substrate 16 lowers toward the substrate 19 as the solder ball 18 melts. Since the reflow temperature of the solder ball 18 is lower than that of the extensible solder bump 14, the bump 14 remains solid during the heating so as to contribute to preventing the substrate 16 from going down to the level lower than the height B.

Abstract: PROBLEM TO BE SOLVED: To provide a device for extending mutual connection and junction between two substrates in an electronic circuit module. SOLUTION: A device applies separating (extending) force to two substrates 16 and 28 through the use of an expandable metal 20. A lift rod 25 mounted on a clamp bridge is moved upward by the expansion of the expandable metal to lift the fixed first substrate 16. A lift bridge 17 coupled to the clamp bridge is moved downward and is kept, in contact with the second substrate 28 connected to the first substrate.

Abstract: PROBLEM TO BE SOLVED: To provide an optoelectronic assembly for a computer system with respect to a mounting structure to establish optoelectronic communication between an electronic chip on a first level package and a high-density light transmitter-receiver. SOLUTION: The optoelectronic assembly includes an electronic chip 110, a substrate 120, an electric signaling medium 140, an optoelectronic transducer 160, and an optical coupling guide 170. The electronic chip is in communication with the substrate, which is in communication with a first end of the electric signaling medium. A second end of the electric signaling medium is in communication with the optoelectronic transducer. The optical coupling guide positions an optical signaling medium with respect to the optoelectronic transducer. An electric signal from the electronic chip is transmitted to the optoelectronic transducer via the substrate and the electric signaling medium. The electronic chip and the optoelectronic transducer share a common heat spreader. COPYRIGHT: (C)2005,JPO&NCIPI
