Zinc whiskers can pose significant problems if not addressed. Despite their innocuous name, they can cause considerable disruption in data centres. While monitoring temperature and having an effective layout can mitigate risks, it’s crucial to remain vigilant about this concealed threat. Zinc whiskers are tiny filaments that form on steel surfaces electroplated with zinc. Zinc protects against corrosion, but the molecular stress from the electroplating process causes it to expand and crystallise to relieve the pressure. They start at only a few microns but can grow to several millimetres. It’s important to note that various surfaces develop whiskers at different rates and densities. Zinc whisker growth is unpredictable, but it is believed to be influenced by the conditions during the electroplating process itself. The tiny shards can lead to catastrophic consequences for data centres. They can remain undisturbed for years on floor tiles and other structural supports. While they are more prevalent in older data centres that used electroplated zinc, they can form on this material anywhere, regardless of environmental conditions. Hazards Unchecked zinc whiskers can lead to everything…
