Abstract

하부 금형 다이의 상부면으로 돌출되는 고정 핀이 리드프레임의 다이 패드의 고정용 홈에 삽입되도록 하여 반도체 칩 패키지의 성형 수지의 몸체를 성형하는 동안 열 방출부를 고정하여 그 열 방출부가 유동하는 것을 방지함으로써 완성되는 반도체 칩 패키지의 몸체의 외관상 불량 발생이 억제될 수 있다.Fixing pins protruding to the upper surface of the lower mold die are inserted into the fixing grooves of the die pad of the leadframe to fix the heat dissipation portion during molding of the molding resin body of the semiconductor chip package, thereby preventing the heat dissipation portion from flowing. As a result, appearance defects of the body of the semiconductor chip package to be completed can be suppressed.

인쇄회로기판의 BT(Bismaleimide Triazine) 레진상의 금 도금된 다이 패드와, 종래의 접착제 사이에 접착 강화제가 추가로 개재되어 반도체 칩이 그 다이 패드상에 견고하게 접착됨으로써 그 다이 패드와 반도체 칩 사이의 박리가 발생하는 것이 방지되어볼 그리드 패키지의 신뢰성이 향상되는 효과가 있다.The gold-plated die pad on the BT (Bismaleimide Triazine) resin of the printed circuit board and an adhesive enhancer are additionally interposed between the conventional adhesive so that the semiconductor chip is firmly adhered to the die pad, thereby Peeling is prevented from occurring, so that the reliability of the ball grid package is improved.
