Claims (2)
- 기판에 실장된 LED 칩으로부터 발산되는 빛을 상부로 방사되도록 유도하는 반사판 레이어를 구비한 LED 칩 실장 인쇄회로기판을 제작하는 방법에 있어서,
(a) 절연층 양면에 동박이 피복된 자재를 반사판 레이어로 하고, LED 칩과 정렬될 부위에 드릴 가공을 해서 반사판 레이어의 선정된 위치에 캐비티를 형성하는 단계;
(b) 상기 반사판 레이어 전체에 대해 동도금을 실시해서 상기 캐비티의 내벽면과 절연층 양면의 동박 위에 동도금층을 형성하여 반사판 레이어를 형성하는 단계; 및
(c) 표면에 LED 칩이 실장된 인쇄회로기판 위에 상기 반사판 레이어를 포개어 적층하되, LED 칩이 상기 반사판 레이어의 캐비티 공간 속에 정렬되도록 적층하되, 상기 LED 칩에서 발산되는 빛이 캐비티 공간을 통해 상기 동도금으로 피복된 캐비티 내벽을 반사하며 캐비티 상부 개구부로 방출되도록 위치를 정렬해서, 상기 반사판 레이어와 인쇄회로기판의 접합면을 본딩시트로 접착하여 고정하는 단계
를 포함하는 LED 칩 실장 인쇄회로기판 제조방법. - 삭제
