RFID can be used during manufacturing, particularly for printed circuit board (PCB) assembly, where identification and work-in-process tracking is key. PCB manufacturing involves multiple steps, from initial inspection to component assembly, testing, and system integration. At each step, unique information needs to be assigned to a precise board, and the amount of data has only increased of late. Work-in-process tracking provides a more accurate, real-time method of reading serial numbers, which can lead to increased productivity.
