    • PROBLEM TO BE SOLVED: To satisfy both of excellent heat dissipating characteristic and reduction in manufacturing cost. SOLUTION: A punched lead frame 3 serves not only as the wiring pattern of a control circuit 8 and a power circuit 9 but also as external terminals 15 and 17.

In other words, the manufacturing cost can be reduced without degrading the heat dissipating characteristic. COPYRIGHT: (C)2004,JPO
