- 원판에 회로를 형성하고 무전해동도금을 실시한 다음 감광성 필름을 적층하고 노광 및 현상으로 범프를 형성하고자 하는 위치에 적층된 감광성 필름을 박리시키는 단계;상기 단계에서 감광선 필름의 박리부위에 일정 두께로 전해동도금하여 범프를 형성하고, 상기 범프의 상부에는 범프간 접속을 위한 Sn/Pb도금층을 일정 두께로 형성하는 단계;상기 단계후에 감광성 필름을 박리하고, 원판 표면의 Sn/Pb 도금층을 제외한 무전해동도금층을 알칼리 에칭액을 이용하여 제거하고 나서 접착력 향상을 위해 산화물(Oxide)처리를 수행하는 단계;상기 단계에서 산화물 처리가 종료된 원판과 원판 사이에 상기 범프의 형성 위치에 소정 직경의 구멍이 가공된 결합시트를 삽입하고, 상기 결합시트와 원판과의 정합을 위하여 가공된 기준 홀을 정합한 다음 적층을 실시하는 단계; 그리고,상기 단계에서 적층이 끝나면 표면에 돌출된 범프 및 산화처리(Oxide)층을 제거하는 샌딩(Sanding)처리를 수행하는 단계를 포함하는 범프를 이용한 고집적 인쇄회로기판의 제조 방법.
- 제 1 항에 있어서, 상기 범프는 30㎛두께로 형성되는 것을 특징으로 하는 범프를 이용한 고집적 인쇄회로기판의 제조 방법.
- 제 1 항에 있어서,상기 Sn/Pb 도금층은 Sn : Pb의 비율이 63 : 37인 것을 특징으로 하는 범프를 이용한 고집적 인쇄회로기판의 제조 방법.
- 제 1 항에 있어서,상기 Sn/Pb 도금층은 10㎛두께로 형성되는 것을 특징으로 하는 범프를 이용한 고집적 인쇄회로기판의 제조 방법.
- 제 1항에 있어서, 상기 범프의 형성위치는 비어 홀이 가공되지 않은 원판에는 일반 랜드(Land)이고 비어 홀(Via Hole)이 가공된 원판에는 비어 홀의 랜드(Land)인 것을 특징으로 하는 범프를 이용한 고집적 인쇄회로기판의 제조 방법.
- 제 5 항에 있어서, 상기 비어 홀의 랜드에는 상기 범프의 형성과 홀의 내부에 도금이 동시에 진행되는 것을 특징으로 하는 범프를 이용한 고집적 인쇄회로기판의 제조 방법.
- 제 1 항에 있어서, 상기 결합시트는 프레프레그(Pre-preg)인 것을 특징으로 하는 범프를 이용한 고집적 인쇄회로기판의 제조 방법.
