PROBLEM TO BE SOLVED: To provide an expensive semiconductor resin sealing die which can eliminate the need of a flash removal step and solve problems of scratches in the contact of a substrate caused by resin flashes and a connection failure caused by the deposition of the resin flashes, and can prevent wire damage caused by the warpage of the substrate in a resin filling direction by a simple structure and high versatility, by removing resin flashes resulting from a gap between the die and the substrate. SOLUTION: Approaching pins 1 each having a tilted surface in its lower end are provided to be projected at positions which are located at edges of opposing surfaces of an upper cavity block 23 adjacent to cull blocks 25, and correspond to positioning holes 71a of a substrate 70. When the substrate 70 is clamped by the upper and lower cavity blocks 23, 53, the tilted surface provided in the lower end 1a of the approaching pin 1 is pushed against the opening edge of the positioning hole 71a of the substrate 70 so that the substrate 70 is slidably moved while being pushed. Consequently, the side end face 72 of the substrate 70 is pushed against the inner side surface of the lower cavity block 53. COPYRIGHT: (C)2005,JPO&NCIPI |
