Research on recycling method of discarded PCB based on cost-profit model

摘要

The efficient reclamation of printed circuit board (PCB) is of important significance to environmental protection, optimal configuration of resources and development of circulation economy. In the paper, several important physical mechanical recycling strategies of PCB were analysed, and a cost-profit evaluation model for these recycling strategies was established to evaluate reclamation profit quantitatively. With one specific recycling example, an accurate economic analysis of it was given by the use of the evaluation model. Finally, the best recycling strategy of the mainboard was acquired and some suggestions were given to improve the reclamation economy.
