Henkel Develops New Electrically Conductive Adhesive
Electrically conductive adhesive used with components.
Irvine, CA — In a significant formulation breakthrough, Henkel Electronic Materials has developed a new electrically conductive adhesive (ECA) compatible with lower-cost, tin-terminated components to enable more cost-effective assembly processes. The new material, Ablestik ICP-3535M1 is a one-component, pre-mixed ECA that provides low and stable contact resistance when used with 100 percent tin-terminated components.

The benefits of ECAs are well-established and include lower temperature processing, more streamlined manufacturing techniques, lower stress assemblies and regulatory-compliant lead-free formulations. Historically, one of the few drawbacks associated with ECAs has been the materials' inability to cope with non-noble metals on component terminations, making them useful primarily with palladium silver-, silver-, or gold-finished components. Ablestik ICP-3535M1 now delivers all of the aforementioned benefits with the added advantage of tin compatibility, thereby enabling high-performance and cost-efficient processes.

The reliability of the new material has been confirmed through various analyses, maintaining its stable contact resistance and good mechanical integrity after 3,000 hours of temperature and humidity testing, 3,000 cycles of thermal shock evaluation and 3,000 hours of heat storage. In each case, it outperformed competitive samples against which it was tested. In addition, the new ECA also exhibits excellent performance with very small components such as 0402s, displaying absolutely zero bridging or wicking with highly miniaturized devices.

The new ECA is particularly well-suited for a variety of automotive applications, but also has relevance for any environment where high reliability and cost reduction targets are important. These may include the aerospace sector, wireless datacom infrastructure (WDI) products, security devices, lighting technology and others.
