Patent number: 6760968Abstract: A die packing device including die holding mechanism comprising a connecting wire receiving shaft which is movable up and down, a pair of die holding levers which have die holding sections for holding the die and are installed so that these levers are free to open and close, and opening-and-closing levers that open and close the die holding levers. A die formed with connecting wires on its upper surface is pushed up by a die push-up device and the wires of to die come into contact with the connecting wire receiving shaft of the die holding mechanism. When the connecting wire receiving shaft is raised by a given amount by the upward movement of the die, the die holding levers are closed so that the die holding sections of the die holding levers are positioned beneath the undersurface of the die. Afterward, the push-up needles of the die push-up device are lowered, resulting in that the die is held by the die holding levers.Type: GrantFiled: October 26, 2001Date of Patent: July 13, 2004Assignee: Kabushiki Kaisha ShinkawaInventors: Tsutomu Mimata, Osamu Kakutani

Publication number: 20020062916Abstract: A method and apparatus for processing semiconductor pellets that are bonded on a wafer substrate that is comprised of a base plate, a heat-shrinkable adhesive agent and a radiation-curable adhesive agent. Prior to supplying the wafer substrate to a pellet pickup section, the adhesive strength of the radiation-curable adhesive agent is weakened by irradiating the wafer substrate with, for instance, ultraviolet light, then a heat treatment is performed by a heater so as to cause heat shrinkage of the heat-shrinkable adhesive agent and to reduce the bonded area between the radiation-curable adhesive agent and the semiconductor pellets. Afterward, the wafer substrate is supplied to the pellet pickup section, and the semiconductor pellets on the wafer substrate are picked up by a suction-chucking nozzle.Type: ApplicationFiled: November 27, 2001Publication date: May 30, 2002Applicant: KABUSHIKI KAISHA SHINKAWAInventor: Tsutomu Mimata

Patent number: 5059559Abstract: The present invention relates to a multi-pin chip mounting method and apparatus based on a TAB (Tape Automated Bonding) system in which leads formed on a tape and bumps formed an IC chip are aligned with each other and compress-bonded to each other. An IC chip having bumps formed on a surface thereof and inner leads formed on a carrier tape are disposed opposite to each other at a bonding station. A position of the IC chip on a stage is detected through the inner leads at the bonding station to determine the amount of correction of position of the stage. The inner leads and the IC chip are aligned with each other on the basis of the determined correction amount and are thereafter bonded to each other.Type: GrantFiled: November 1, 1988Date of Patent: October 22, 1991Assignee: Hitachi, Ltd.Inventors: Michio Takahashi, Tooru Mita, Yasuo Nakagawa, Toshimitsu Hamada, Hisafumi Iwata, Aizo Kaneda, Kouji Serizawa, Hiroyuki Tanaka, Koichi Sugimoto, Toshihiko Sakai, Keizo Matsukawa, Tsutomu Mimata

Patent number: 5015425Abstract: A manufacturing apparatus has a clean air supply means provided integrally with a part thereof for supplying clean air toward at least an area in which a workpiece exists, and an air discharge means disposed so as to face the clean air supply means across the workpiece and adapted to discharge the air to the outside of the apparatus. It is therefore possible for clean air to be constantly supplied to the workpiece area under positive pressure. Thus, there is no risk of dust generated not only inside but also outside the apparatus being moved to the vicinity of the workpiece. Accordingly, it is possible to prevent adhesion of dust to the surface of the workpiece by the apparatus alone and also possible to install the apparatus as desired.Type: GrantFiled: September 25, 1989Date of Patent: May 14, 1991Assignee: Hitachi, Ltd.Inventors: Tsutomu Mimata, Toshihide Uematsu, Katsuhiro Tabata
