Indium Corporations Ron Lasky, Ph.D., PE, senior technologist, will host a webinar on intermetallics and their importance to solder joints on Tuesday, Sept. 21, 10 a.m. San Francisco/1 p.m. New York/6 p.m. London/7 p.m. Germany as part of the companys free webinar program, the InSIDER Series.
The formation of copper-tin intermetallics is fundamental to a functional solder joint. In creating most solder joints, two pieces of copperwhich melt at 1085Care bonded together with solder, at less than 250C.
Most of us, with years of experience in electronic assembly, dont usually think of this technological miracle of soldering. We are able to bond two pieces of copper together at a temperature low enough where the bonding can be performed in the presence of polymer material. Without this low-temperature formation of copper-tin intermetallics, the electronic industry might not exist, said Dr. Lasky. However, contemporary wisdom is that these intermetallics are brittle and can result in poor thermal cycle or drop shock performance.
In this webinar, Dr. Lasky will review the formation of copper-tin intermetallics, their growth rate, their effect on thermal cycle life, and drop shock performance. The brittle nature of copper-tin intermetallics will also be discussed. In addition, several graphs of intermetallic growth rate will be presented. Some of the additional ancillary effects of copper-tin intermetallic growthsuch as tin whiskers and their mitigationwill also be discussed.
Dr. Laskys webinar is offered as part of Indium Corporations free webinar program, the InSIDER Series. You can register for his webinar at https://indium.news/3zosh98.
