Abstract
일반적으로 인쇄회로기판(Printed Circuit Board, PCB)은 다양한 종류의 플라스틱에 세라믹과 금속 성분이 복합적으로 함유되어 있는 것으로 알려져 있다. 따라서 환경적인 보호뿐만 아니라 자원의 재활용의 관점에서 PCB 스크랩으로부터 금속 성분을 분리해내는 것은 중요하다. 본 연구에서는 PCB의 재활용 기술에 대한 특허와 논문을 분석하였다. 분석 범위는 1980년~2011년까지의 미국, 유럽연합, 일본, 한국 등 다양한 나라의 등록/공개된 특허와 SCI 논문으로 제한하였다. 특허와 논문은 키워드를 사용하여 수집하였고, 기술의 정의에 의해 필터링 하였다. 특허와 논문의 동향은 연도, 국가, 기업, 기술에 따라 분석하여 나타내었다. It is generally well known that PCB (Printed Circuit Board) is an electric component assembled by various metals mixed with plastics and ceramics. Accordingly, it is very important to extract metallic components from used PCBs from the point of view of recycling of used resources as well as an environmental protection. In this paper, patents and paper on the recycling technologies of PCB were analyzed. The range of search was limited in the open patents of USA (US), European Union (EP), Japan (JP), Korea (KR) and SCI journals from 1980 to 2011. Patents and journals were collected using key-words searching and filtered by filtering criteria. The trends of the patents and journals was analyzed by the years, countries, companies, and technologies.
