Mhlbauer, Intune and Delo start RFID research project

RFID production specialist Mhlbauer has joined forces with Delo Industrial Adhesives and Intune Circuits – a Finnish manufacturer of RFID antennae – to research turnkey solutions for the manufacturing of RFID label inlays.

The compatibility of different antennas, adhesives and production machines was extensively tested at Delo’s laboratories and at Mhlbauer over several months.

The key objective was to research adhesive compatibility between the antenna lamination and the semiconductor chips. Mechanical properties were tested in several laboratory tests and different climate tests were carried out to simulate the lifetime of a bonded connection between antenna and chip.

Also tested was fast cure in the thermode station, where the chip is pressed onto the antenna to ensure electrical contact.

The tests demonstrated that heat-curing epoxies like Delo-Monopox MK055 and Delo-Monopox AC265 are best suited for bonding onto Intune’s standard aluminum UHF antennas. Both products were processed on Mhlbauer’s production system.

The three partners are promoting the systems as an optimized ‘plug-and-play’ solution for the efficient production of RFID inlays.
