废印刷电路板回收处理技术的研究进展

Research Progress of PCB Scrap Reclamation Technology

随着信息社会发展速度日益加快,电子电器产品数量的增长以及产品更新换代速度也不断加快,由此产生了大量的电子废弃物,并以每年近10%的速度增长。文章主要介绍了废旧印刷电路板(PCB)回收利用问题,综述了目前几种重要的常规废印刷电路板回收处理技术,并对这些方法做了简要的分析。还着重介绍了两种极具发展前景的新型废印刷电路板回收处理技术。

With the double-quick development of information-based society, the number of electronic and electric product is becoming more and more heavy, as well as its twice-born rate is accelerating. Therefore, a large number of electronic waste is produced, and the annual growth approaches 10 %. In the paper, the reclamation of waste printed circuit board （PCB） was discussed, several important current conventional recycling technologies of PCB was reviewed, and the brief analysis of these methods was given. The paper also focused on the two new PCB recycling technologies, which had big developing prospects.
