Abstract
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.
