Abstract
접속 불량이 없는 필드 비아를 형성할 수 있는 프린트 배선판의 제조 방법, 및 그 프린트 배선판을 제공한다.
해결 수단
비아용 개구 (60) 의 내벽에 무전해 도금막 (62) 을 형성한 후, 절연성 수지 기재 (56) 에 전해 도금을 실시하고, 비아용 개구 (60) 에 도금 금속을 충전시켜 필드 비아 (68) 를 형성한다. 이 때문에, 전해 도금시에 비아용 개구 (60) 의 저부에 추가하여, 비아용 개구 (60) 측벽의 무전해 도금막 (62) 으로부터도 도금 금속이 석출된다. 그 결과, 전해 도금에 의해 비아용 개구 (60) 를 완전히 충전시켜, 접속 불량이 없는 필드 비아 (68) 를 형성할 수 있다.
