Title: Diode, diode press-fitting method, diode mounting method and fin
Inventor: EZAKA KAZUAKI
IPC: H01L23/40
Filed: 2002-02-14
Abstract: <P>PROBLEM TO BE SOLVED: To suppress the deformation of an Si element.  <P>SOLUTION: In the diode press-fitting method for press-fitting the diode equipped with a heat sink having a disk-like bottom and a semiconductor pellet provided on one side of the bottom for converting an AC to a DC into a through hole provided on a radiating fin, the diode is press-fitted into the through hole by mainly applying a load to the outer periphery of the other side of the bottom. Thus, the outer periphery of the bottom of the heat sink is pressed towards the center. Therefore, since the center on the bottom of the heat sink receives stress in anti-press-fitting direction, the bottom of the heat sink is deformed into spherical projection in the anti-press-fitting direction. Therefore, the semiconductor pellet is deformed into spherical projection to the bottom side of the heat sink and the semiconductor pellet receives stress inverse to a deforming direction from the bottom of the heat sink. Thus, the deformation of the semiconductor pellet can be suppressed.  <P>COPYRIGHT: (C)2003,JPO
