DELO Industrial Adhesives, Mühlbauer, and Impinj, Inc. recently announced a milestone in the effort to achieve high-volume inlay manufacturing. The three companies report that they have successfully teamed to deliver DELO MONOPOX AC6545, supporting the high-speed assembly of copper-bonded RFID chips such as the Impinj Monza 6 family on Mühlbauer high-speed assembly lines.

The new adhesive is reportedly a key step forward on the “Path to 100k UPH,” manufacturing 100,000 RAIN RFID labels per hour on a single assembly line. Achieving this goal will empower inlay manufacturers to increase throughput and reduce operating costs, allowing RAIN RFID tagging to scale across high-volume industries such as apparel, retail, shipping, and airline baggage tracking.

Reportedly featuring excellent adhesion to copper, DELO MONOPOX AC6545 enables the high-speed assembly of copper-plated chips such as the Impinj Monza 6 family. The solvent-free, anisotropic conductive adhesive (ACA) can be applied by innovative jetting technologies and also delivers improved performance with gold-bonded chips.

In addition to rapid dispensing, extremely quick curing is essential to support the fastest assembly speeds. This product reportedly allows for curing times as low as 1 sec when using a thermode at 230°C, making it one of the fastest products in DELO’s portfolio of RAIN RFID adhesives. With higher temperatures, even shorter curing times can be achieved.

With these improved ACA curing times, Mühlbauer’s direct die attach (DDA) can produce over 40,000 units/hr. For more than three years, customers have reportedly operated DDA machines 24 hrs per day/seven days a week. Going forward, the Mühlbauer roadmap includes increasing machine capacity to 100,000 units/hr and full automation over the complete inlay production chain to improve the yield and reliability of the final assembly.

“The fact that our adhesives are in 80% of the billions of RAIN RFID labels produced annually is a result of our high commitment to advancing the industry,” said Karl Bitzer, head of Product Management for DELO. “We have always taken the challenges of our customers very seriously and with this latest innovation, we continue to solve their problems.”
