电子元器件广泛应用于电子电器设备中，但由于产品更新换代和电子电器产业市场的膨胀，大量的电子元器件被丢弃。对电子元器件的资源性和危害性进行分析，综合评述了电子元器件回收利用的最新研究进展和成果，主要包括电子元器件的拆卸技术（解锡方法和分离方法）和回收技术。在此基础上，提出了废旧印刷电路板中电子元器件的无害化和资源化回收研究新动向及发展建议。
Electronic components are widely used in the electronic and electrical appliances.However,large quantities of electronic components are coming into discarding period due to the endless requirement for new products and market explosion for electronic and electrical products.The valuable materials and toxic materials of electronic components are analyzed.The new recycling processes for electronic components are reviewed,including the disas-sembling technologies (unsoldering methods and separation methods)and recycling technologies.On this basis,some new trends and suggestions on recovery of electronic components in waste printed circuit boards (WPCBs)are put for-ward.
