Title: Method and device for pressurizing solder foil
Inventor: HASEGAWA SHINICHI
IPC: B23K1/00
Filed: 1990-11-20
Abstract: PURPOSE:To prevent a foil from being floated and a nest of blow hole from being generated by introducing inert gas into a chamber of a solder foil holding block to join solder foils with the exerted pressure. CONSTITUTION:When a lead frame 1 is mounted at a prescribed position, a die pad part 2 is heated by a heating body block 3 to a prescribed temperature. Then, the solder foil 5 is sucked by a sucker 6a of a holding block 6 and as it is lowered to the bottom dead center, inert gas is discharged from an inert gas introducing hole 7 to join the solder foil 5 to the surface of a die pad part 2 with the exerted pressure. Since the inert gas is not used in a conventional solder foil pressing device, when a parallelism between the solder foil holding block and the heating block is not adjusted fully, the device had considerations making causes to generate the float. This invention can dissolve these considerations.
