废弃线路板资源化利用研究

Study on Reutilization of Waste Printed Circuit Boards

印刷线路板被广泛应用于各类电子电气设备中,但随着电子电气产品更新换代的加速和电子电气产业市场的膨胀,每年产生大量的废弃线路板。为避免废弃线路板对环境可能造成的污染,同时减少相关资源浪费,社会对废弃线路板资源化的要求越来越高。叙述了废弃线路板的来源及特征,分析了目前废弃线路板资源化利用方面的工艺。在此基础上,结合实际,提出了提高废弃线路板资源化利用水平的建议。

Printed circuit boards are widely used in diverse electrical and electronic equipment.However,large quantities of waste printed circuit boards(WPCBs)are produced each year due to the endless upgrading of electrical and electronic products and expansion of the electrical and electronic industry market.In order to avoid the possible environment pollution and the waste of related valuable resources,increasing attention is focused on reutilization of the WPCBs.This paper described the sources and characteristics of the WPCBs,and analyzed the current technologies in reutilization of the WPCBs.On this basis and combined with the reality,suggestions were put forward to improve the reutilization level of the WPCBs.
