WebMetal whiskering is a phenomenon which occurs in electrical devices when metals form long whisker-like projections over time. Tin whiskers were noticed and documented in the vacuum tube era of electronics early in the 20th century in equipment that used pure, or almost pure, tin solder in their production. It was noticed that small metal hairs ... WebAfter the termination has been fired or sintered it is then electroplated with a nickel layer to minimize dissolution during soldering and is finally plated with a solder or tin layer to preserve solderability of the nickel layer.
