Experimental Study on Impact Mechanical Properties of Waste Printed Circuit Boards
Comminution is a key part of the reutilization of discarded circuit board.In order to find out the most appropriate method of crushing,the characteristics of the materials and the mechanical properties of resistance impact of discarded circuit boards were studied.The substrate of circuit boards,slots of ISA and PCI were adopted as the specimen.The scanning electron microscope (SEM) and energy disperse X-ray spectroscopy (EDX) were used to characterize and analyze the combined state of the fracturing materials on the specimen surfaces after comminution.Results showed that the metals and nonmetals in the slots were crushed and dissociated easily.At the same time,the metal and nonmetal combined interfaces in the substrate have a trend to be broken and separated under the impact effect,which means the crushing circuit board has a favorable break effect under impact load.
