Pb-free solder alloy available for
high-temperature applications

Developed alongside and accepted by the automotive industry, Henkel announces the commercial availability of 90iSC, a high-reliability, lead-free solder alloy for demanding high-temperature applications. The alloy, which addresses the drawbacks certain products experience with traditional SAC alloys, has been proven as a viable lead-free solution for applications where extremely high reliability is required. Henkel’s high-reliability solder alloy, 90iSC, is a multi-component alloy based on traditional SAC but with improved temperature resistance and reliability characteristics. The alloy has a wide temperature cycling range from -40 to 155 degrees Celsius, optimized creep resistance at high temperature, vibration and drop test performance comparable to SAC and other lead-free alloys and has printing and reflow behavior consistent with alternative lead-free materials, making it an ideal drop-in replacement. In addition, 90iSC offers automotive manufacturers, many of whom have not yet transitioned to lead-free materials, an alloy that delivers creep resistance, thermal cycling and thermal shock performance, as well as drop and vibration test results equal or superior to SnPb solders.

In addition to its exceptional performance with high-reliability applications, 90iSC is compatible with several Henkel lead-free and halogen-free flux systems, ensuring adaptability for customized manufacturing requirements. The unique alloy is easily integrated, for example, with market-leading lead-free flux system Loctite Multicore LF318 and high print speed halogen-free flux formulation Loctite Multicore HF200, making these high-performance, high-reliability flux technologies even more powerful.
