Abstract

PURPOSE:To provide a resin sealed device of high quality and high reliability by use of lead wires provided at their full surfaces with a solder film. CONSTITUTION:A solder film is formed on the entire surfaces of lead wires 1a through 3a. When the lead wire 1a is heated in N2 to melt the solder on the surfaces thereof and rubbed against the collector electrode of a pellet 6a, the collector electrode of Ti-Ni-Au structure is easily soldered on the lead wires. Then the emitter and base electrodes are connected 7 to lead wires 2a and 3a by heat press-fitting. As the solder on the lead wires, a silver-containing high melting point solder is used to prevent the movement of the pellet by the heat pressure fitting. Ultimately, the required parts of the lead wires are sealed with a resin. In this organization, a film of a precious metal layer is unrequired, and the cost for material is reduced. The pellet press fitting temperature can be lowered by more than 1000 deg.C as compared with that of the conventional method, and therefore no characteristic deterioration of the pellet is produced and the reliability of the device is improved.
