Abstract

본 발명은 레진 댐바를 갖는 리드프레임에 관한 것으로, 통상적인 댐바 부분에 적어도 하나 이상의 돌기를 형성하여 레진 댐바의 유동을 방지하여 성형 공정시에 성형 금형의 캐비티 내로부터 프래쉬가 배출되는 것을 방지할 수 있는 것을 특징으로 한다.The present invention relates to a lead frame having a resin dam bar, and to form at least one protrusion in the conventional dam bar portion to prevent the flow of the resin dam bar to prevent the discharge of the flash from the cavity of the molding die during the molding process. It is characterized by being.
