Title: Jig for heat-insulating box
Inventor: YAMAZAKI MIKI
IPC: F25D23/08
Filed: 1988-09-21
Abstract: PURPOSE:To prevent generation of a part not filled with a foamed powder or generation of a deformation by forming an inner jig corresponding to an inner box by use of a good heat conductor, and providing a thin resin layer on a surface brought into contact with the inner box, along the shape of the inner surface of the inner box. CONSTITUTION:A heat-insulating box A is placed between an inner jig 3 and an outer jig 4. A raw liquid of a foamable heat-insulating material, e.g. foamable polyurethane, is poured between an inner box 12 and an outer box 3 of the heat-insulating box a, and the assembly is placed into a furnace to foam the foamable material by heating. After the heating is finished, the assembly is left in a heat-insulated condition. In this period, accumulation of heat is not liable to occur, because a resin layer 8 is thin, a base material 6 is a good heat conductor, and the base material 6 dissipates favorably the heat generated by the foamable material itself at the time of foaming. Thus, generation of a part not filled with the foamed material or a deformation of the outer or inner box is unlikely to occur, even in a summer season. Further, heat is released in a short time, so that it is possible to contrive a reduction in a cooling time for a foaming step.

Title: Soldering of electronic component
Inventor: IMAIZUMI NORIHISA
IPC: H01L25/04
Filed: 1998-08-24
Abstract: PROBLEM TO BE SOLVED: To prevent voids from being generated to the utmost in the soldered part of an electronic component in the case where the electronic component is mounted on a board by reflow soldering. SOLUTION: This soldering method is executed as follows: a solder paste 8 is fed to a board 1 and thereafter, before an electronic component is mounted on the paste 8 and is reflow-soldered to the board 1, the paste 8 is heated at a temperature (70 to 150 deg.C) in the degree that the powder solder in the paste 8 is not molten. According to this method, as the paste 8 is heated in the process previous to the process for mounting the component, the low-boiling point content in a flux is vaporized at the time of the heating. Therefore, when the component is reflow-soldered, vapor can be prevented from being generated to the utmost and can be prevented from being remaining as voids to the utmost.
