Inverse production strives for a selective dismantling of industrial mass products at their end-of-life (EOL) with the goal to generate highly enriched fractions of valuable materials for subsequent tailored recovery procedures. Since in many cases there is only fragmentary or even no information available about the chemical composition of such EOL-products and their components, there is a need for a fast, inline, multi-element, stand-off analyzing methodology, that can be integrated in an inverse production line. Within the European project ADIR, LIBS was studied to identify valuable materials in electronic components and to allocate this analytical information to the location of the measuring object on the printed circuit boards of the EOL-product. The fused data set of physical – gained via 2D, 3D geometry measurements – and chemical data allows for a selective disassembly and sorting of such electronic components. This paper describes the developed scanning LIBS method, gained results, and the integration of the LIBS measurements in the worldwide first inverse production line to process printed circuit boards of servers and cell phones.

反向生产致力于在寿命终止（EOL）时选择性拆除工业大宗产品，目标是为后续定制的回收程序生成有价值的材料高度浓缩的馏分。由于在很多情况下，关于此类EOL产品及其成分的化学组成只有零碎的信息，甚至没有信息，因此需要一种快速，在线，多元素，稳定的分析方法，可以将其整合在逆向生产线上。在欧洲ADIR项目中，对LIBS进行了研究，以识别电子元件中的有价值材料，并将此分析信息分配给EOL产品的印刷电路板上测量对象的位置。通过2D获得的物理融合数据集，3D几何测量–以及化学数据可选择性地拆卸和分类此类电子组件。本文介绍了已开发的扫描LIBS方法，获得的结果以及LIBS测量值在全球第一条反向生产线中的集成，以处理服务器和手机的印刷电路板。
