Automatic printing of caution labels for moisture-sensitive devices

摘要

A novel system is provided for automatically generating caution labels for moisture-sensitive semiconductor devices packed in drypack bags. The system has a scanner that scans a lot number or an ID mark representing ID information of a moisture-sensitive device sealed in a drypack bag, and a computing device with a look-up table containing moisture-sensitivity levels assigned to the moisture-sensitive devices. In response to an ID signal produced by the scanner, the computing device searches the look-up table for a moisture-sensitivity level assigned to the packed moisture-sensitive device. The determined moisture-sensitivity level is supplied by the computing device to a label-formatting device for generating a caution label indicating the moisture-sensitivity level. The label-formatting device controls a printer for printing the generated caution label.
