Abstract

본 발명은 다층회로기판을 계단식으로 제조하는 방법에 관한 것으로 계단식으로 각 층마다 본딩패드를 구성하므로서 패키지의 하이 핀화에 대응할 수 있는 다층 회로기판을 제공하는 데 목적이 있다.The present invention relates to a method of manufacturing a multi-layered circuit board in a cascade, and an object of the present invention is to provide a multi-layered circuit board that can cope with high pinning of a package by forming a bonding pad for each layer.

이를 위해 본 발명은 기판위에 2층 패턴을 형성함과 동시에 본딩패드를 형성하는 단계와 상기 2층 패턴위에 상기 본딩패드가 노출되도록 구멍을 뚫은 프리프레그를 깔고 그 위에 구리층을 입힌 후 에칭하여 3층 패턴을 형성함과 동시에 본딩패드를 형성하는 단계와 상기 3층 패턴위에 상기 본딩패드가 노출되도록 구멍을 뚫은 프리프레그를 깔고 그 위에 구리층을 입힌 후 에칭하여 4층 패턴을 형성함과 동시에 본딩패드를 형성하는 단계로 이루어진 것을 특징으로 한다.To this end, the present invention forms a two-layer pattern on the substrate and at the same time forming a bonding pad and spreading a prepreg punched to expose the bonding pad on the two-layer pattern and coating a copper layer thereon and then etching it. Forming a layer pattern and simultaneously forming a bonding pad and spreading a prepreg punched to expose the bonding pad on the three layer pattern, coating a copper layer thereon, and etching to form a four layer pattern and bonding at the same time. Characterized in that the step of forming a pad.

이같이 구조의 본 발명은 본딩패드가 2,3,4층에 모두 형성되어 있어서 기존의 다층회로기판에 비해 2배 이상으로 본딩수를 증가시킬 수 있어 패키지의 하이 핀화에 대처가 가능하다.In the present invention having the structure as described above, the bonding pads are formed on all two, three, and four layers, so that the number of bondings can be increased more than twice as compared to the existing multilayer circuit board, thereby coping with high pinning of the package.
