Title: Mounting of electronic component and heater tool
Inventor: MATSUHASHI KENJI
IPC: H05K3/32
Filed: 1993-12-27
Abstract: PURPOSE:To perform a collective treatment simultaneously a soldering of lead parts to a flexible wiring board and a pressure bonding of a thermally adhered film to the flexible wiring board at the same site for corresponding to a bend mounting and to contrive a shortening of the production process of an electronic component by a method wherein devices are applied to the structure of a heater tool. CONSTITUTION:A flexible wiring board 2 is positioned and is fixed on a printed- wiring board 5. In this state, when a heater tool 1 is made to descend and comes into contact to the upper surface of the board 2, a thermally adhered film 4 on the lower surface of the board 2 is crushed while receiving conduction heat of 130 to 150 deg.C from the tool 1 and a thermocompression bonding of the film 4 to the board 2 is completed. At the same time, the point of the tool 1 comes into contact to leads 3 to strike solder bumps 6 and the tool 1 conducts a soldering of the leads 3 to the board 2 at a heating temperature of 220 to 230 deg.C. At this time, an adhesion of the film 4 to the board 2 already ends and even if the tool 1 is pulled up at this point of time, the unsatisfactory state of the soldering, such as the levitation of the leads 3, is not generated.
