High performance, high reliability ECA from Henkel makes automotive electronics inroads
Versatile Material a Robust Solder Alternative, Compatible with Tin-terminated Components
Henkel’s development of LOCTITE ABLESTIK ICP 3535M1 was a historic breakthrough for electrically conductive adhesives (ECAs), allowing use of the material with a more diverse component range. The material provides a robust alternative to solder for many applications, lowers component assembly stress and facilitates lead-free interconnection for regulatory compliance.
Recently, the versatility and proven reliability of LOCTITE ABLESTIK ICP 3535M1 has led to its acceptance at global automotive electronics manufacturers, where the material is being used successfully for the production of transmission control units and qualified for several other automotive applications.
Reliability is a hallmark of LOCTITE ABLESTIK ICP 3535M1, which a primary reason for its automotive electronics acceptance. Internal and customer qualification testing have confirmed the material’s 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. The material consistently outperformed competitive samples against which it was tested. Excellent performance on smaller components also underscores LOCTITE ABLESTIK ICP 3535M1’s effectiveness for the reduction of defects. Evaluation of the material on 0402 components resulted in zero bridging or wicking, and the material is equally effective on larger devices such MOSFETs.
While LOCTITE ABLESTIK ICP 3535M1 has enjoyed early success in the automotive sector, the material’s versatility extends to any application where low and stable contact resistance, lower stress assembly, regulatory compliance and cost-effectiveness are required. Whereas other ECAs are unable to cope with non-noble metals on component terminations, LOCTITE ABLESTIK ICP 3535M1 succeeds in delivering performance and reliability effectiveness on traditional palladium silver-, silver- and gold-finished components, as well as cost-effective tin-terminated components. Applications within the aerospace, wireless datacom, security and lighting sectors will also benefit from the material’s flexibility, reliability and cost reduction capability.
“The adaptability of the material is unprecedented for an ECA,” notes Ian Wilding, Henkel Global Technology Manager. “Component adaptability is one example, but the material also allows device assembly onto various substrates including OSP-finished PCBs, LTCCs and high-temperature ceramics. Cost savings per board, supply chain simplicity, performance and reliability are all significantly better with LOCTITE ABLESTIK ICP 3535M1 than with conventional ECA materials.”
