  2. 1. Life Cycle Assessment of Paper Based Printed Circuits

    Author : Qiansu Wan; Li-Rong Zheng; Changqing Liu; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Printed Electronics; Environment; PCB; Life Cycle assessment; Emissions; Informations- och kommunikationsteknik; Information and Communication Technology;

    Abstract : Printed circuit boards have been massively manufactured and wildly used in all kinds of electronic devices during people’s daily life for more than thirty years since the last century. As a highly integrated device mainly consists of silicon base, an etched copper layer and other soldered components, massive production of printed circuit boards are considered to be environmentally unfriendly due to the wet chemical manufacturing mode and lack of recycling ability.
