Radio-Frequency Identification: The contact-free way to transfer data thanks to flip-chip bonding

Products at the grocery store, tickets to an event or ski passes: In many places, encrypted information – like personal data, prices and addresses – are saved to be read for identification later. For these tiny RFID chips to do their job, special RFID adhesives are necessary: These special glues fix a tiny RFID chip to an antenna. Here, flip-chip bonding solutions convince with shortest curing times and high reliability.

RFID labels for easier processes

RFID technology makes for more efficient inventory management in many sectors. Handling is much easier when RFID gives you access to detailed information regarding warehouse stock in a matter of seconds. Smart labels, a label with a built-in chip and an antenna, transfers data from an RFID chip to a reader: for an easy, automatic and contact-free process!
