Abstract

본 발명은 칩 패키지에 관한 것으로, 내부리드들의 선단이 성형수지에 대하여 일부 노출되도록 형성하고, 그 노출된 내부리드들의 선단에 대응하여 상기 내부리드들과 분리 형성된 탭 외부리드들이 열압착 방법에 의해 전기적 연결시켜 외부리드들의 솔더 접합 크랙을 방지할 수 있어 칩 패키지의 신뢰성을 개선할 수 있는 특징이 있다.The present invention relates to a chip package, wherein the front ends of the inner leads are partially exposed to the molding resin, and the tab outer leads formed separately from the inner leads in correspondence to the exposed ends of the inner leads are thermocompressed. Electrical connection prevents solder joint cracking of external leads, which improves chip package reliability.
