PURPOSE:To enable mounting of the semiconductor device on an AC generator for a vehicle which vibrates extremely by sealing a semiconductor element and electrode lead wires connected to the element with a protecting material and reinforcing the surface of the material with an enclosure and sealing material. CONSTITUTION:An electrode plate 3 and lead wires 2 are connected to the semiconductor element and a conductive plate 4 used also as a heat dissipating plate is connected to the electrode plate 3. After the semiconductor element and the lead wires 2 are sealed with the protecting material 7, a ring-shaped sealing material 8' made of thermocurable adhesive and the enclosure 5 are sequentially engaged with the lead wires 2. An assembly thus associated is plated upside down, and is heated to melt the sealing material 8. Thus, a suitable amount of the sealing material 8 is immersed into the through hole 6 of the enclosure 5. The assembly is again placed upside down at this time, and the enclosure 5 is pressurized. Thus, the connecting part is rigidly maintained with excellent vibration-proof, electric, heat insulating and airtight properties. |
