Pyrolysis of Printed Circuit Boards [PDF]
International Journal of Metallurgical Engineering, 2013 Printed Circuit Board (PCB) is an essential co mponent of almost all electrical and electron ic equip ments. The rapid growth of the use of such equipments has contributed enormously to the generation of large quantity of waste PCBs. The WPCBs not only contain valuable metals but also a large variety of hazardous materials.
