Abstract
UV fluorescent additives are added to primary sources of plastic resins or adhesive formulations to serve as tracers and contamination-detection aids. When a plastic or adhesive particle/debris is detected in failed hard disk drives (HDDs) or at other locations, the different tracers added in different plastic or adhesive items (such as trays, assembly tools, direct plastic components, or adhesives used on direct components or indirect materials in manufacturing processes) help identify and narrow down the source(s) of the plastic or adhesive particle/debris.
