Attaching the thermally conductive double-sided tape 10 is inconvenient, takes a long time to reduce assembly productivity, and when using the thermally conductive double-sided tape 10, it is difficult to remove the heat sink 4a because it is difficult to recycle. There have been many problems with this.

따라서, 본 발명은 상기한 제반 문제점을 해결하기 위한 것으로서, 인쇄 회로기판의 상부에 간편한 구조로서 용이하게 방열판을 고정시킬 수 있도록 하여 조립 생산성을 향상시킬 수 있으며, 제작 단가를 크게 절감시킬 수 있을 뿐만 아니라, 인쇄 회로기판에 고정된 방열판을 손쉽게 분리하여 재활용할 수 있는 방열판 고정구조를 제공하는 데 그 목적이 있다.Accordingly, the present invention is to solve the above problems, it is possible to easily fix the heat sink as a simple structure on the upper portion of the printed circuit board to improve the assembly productivity, it is possible to greatly reduce the manufacturing cost Rather, an object of the present invention is to provide a heat sink fixing structure capable of easily separating and recycling a heat sink fixed to a printed circuit board.
