SMTA Europe announces Keynote Speaker Ralph Tuttle of Cree, Inc. on High Power LED Solder Joint Reliability at the “Electronics in Harsh Environments Conference” to be held in Amsterdam, Netherlands, on April 25th, 2018.
Advances in LED technology now allow operation at MUCH higher temperatures while still achieving high lumen output and long lifetimes. While traditional lead-free SAC 305 solder alloys are acceptable for LEDs operating in benign conditions, they are not as reliable when LEDs are operated at high temperatures since they drive high currents. This talk will discuss failure modes associated with LEDs operating under stressful conditions. The research into alloy modifications to package construction will be presented.
