RFID Application

General

Most RFID

(Radio-frequency identification) tags contain at least two parts. One is an integrated circuit for storing and processing information, modulating and demodulating a (RF) signal, and other specialized functions. The second is an antenna for receiving and transmitting the signal. Tresky’s modular die bonding equipment delivers, once more, optimal perfomance in R&D and pre-production assembly as e.g.: Bonding of a Flip-Chip to Antenna.

Flexibility

Tresky’s T-3000 line allows different RFID bonding processes, such as adhesive or ultrasonic bonding. Process parameters can be easely adjusted for optimized results. Temperature, time and force can be adjusted respectively programed independently.

Various Processes

Process - Adhesive Tech. (ACP Anisotropic Conductive Paste)

Dispense ACP glue on antenna. Electroless bumped chip, aligned by beam splitter, placed into glue and cured.

 

Process - Adhesive Tech. (NCP Non Conductive Paste)

Dispense NCP glue on antenna. Stud bumped chip, aligned by beam splitter, placed into glue and cured.

 

Process - Ultrasonic

During placement, the ultrasonic energy is transfered to the chip contacts, where it is transformed into heat.
