LITESURF Plating Technology - Interview with Dr. Erika Crandall, Senior R&D Product Development Engineer. In this video section, you will learn why metallic whiskers are a risk to automotive manufacturers today.
Why are metallic whiskers a risk to automotive manufacturers today?
Why are they such an issue today, they’ve actually been around since as early as the 1940s. But with the use of lead, in tin-lead finishes, tin whisker growth itself was essentially mitigated, and the whole topic was left in the dark and forgotten about for many years. It wasn’t until just a little over a decade ago, when they started bans and restrictions on the use of lead, this resulted in the use of pure tin films, and that is when tin whisker growth really became a big issue. Now when we couple this with the fact that press-fit pin applications are only going to be increasing in our electronic systems due to their high reliability in connection, along with the growing miniaturization trends, of course to save on room and weight, this really becomes a concern for all electronic systems out there. And especially when we look to the automotive sector. Here, our cars have hundreds of pins in every vehicle being produced today.
And this is only going to increase itself, the more we implement high functionality accessories in our cars, and of course, as electric cars, they already have started, but as electric cars slowly and continually replace our motorized cars this is going to become an even bigger issue.
And not to mention that automotive transportation is the number one most widely used form of transportation for passengers today, making this reliability of these systems extremely important to the point of where manufacturers really cannot afford the risk of whisker induced failures.
