Description
Claims (1)
- 걸형 IC 패캐이지를 포밍하는 방법에 있어서, 스트립 형태로 구성되는 다수의 패캐이지간에 위치하여 대응하는 각 리드의 단부가 고착되어 있는 상태의 다수의 분리바를 좌우로 1/2씩 분리시키는 단계와, 분리바를 1/2씩 분리시킨후 다이와 펀치를 이용하여 각 패캐이지의 다수의 리드 단부를 상향 굴곡시키는 제1포밍 단계와, 다수의 리드 단부를 1차 상향 굴곡시킨 상태에서 다이와 펀치를 이용하여 각패캐이지를 다수의 리드를 하향굴곡시키는 제2포밍 단계와, 각리드의 불필요한 단부 및 이에 일체화된 분리바를 절단하는 리드 절단단계 및, 각 패캐이지와 사이드 레일을 분리하여 독립적인 패키이지로 형성하는 단계를 순차적으로 실시하는 것을 특징으로 하는 걸형 IC 패캐이지 포밍방법.
