Embedded RFID TAG inside PCB board to improve supply chain management

Radio Frequency Identification (RFID) is a powerful tool used in several application areas. In this paper a method to embed a passive Ultra High Frequency (UHF) RFID chip within Printed Circuit Boards (PCB) is presented, along with how this can be used to improve the quality and tracking of boards along the electronics supply chain. Embedding of the RFID tag at the very beginning of the supply chain aims to widen the visibility of the product from a very early stage. The embedding of the tag is performed during the bonding process when the multi-layer board is assembled. From this stage onwards it is possible to visualize, record and trace every movement and operation the board goes through along the supply chain.
