Abstract
본 발명에 따른 방열처리구조는 열이 발생하는 발광다이오드가 은나노층을 통하여 인쇄회로기판과 접촉되게 하는 구조로서, 발광다이오드에서 발생하는 열을 기판에서 바로 흡수하여 외부로 방열 처리하므로 종래의 열전달구조에 비해 방열효율을 높일 수 있으며, 광방출 효율향상을 통하여 고출력의 발광다이오드 구현이 가능하고 사용수명을 연장할 수 있으며, 또한 발광다이오드와 PCB 기판 사이에 열전달력이 높은 은나노분말만이 얇은 두께로 게재되므로 열전달 효율이 우수하고 열저항이 최소화되며, 고온의 운전조건에서도 발광다이오드와 PCB 기판의 접착력이 유지된다.
또한, 본 발명의 방열처리방법은 발광다이오드와 PCB 기판을 저온에서 융착시킬 수 있으므로 융착 과정에서 발광다이오드 소자가 손상되는 것을 방지하고 발광다이오드 패키지의 제조원가를 절감할 수 있는 이점이 있다.
