Several times there was a change to pure tin surfaces within the context of RoHS requirements. However, these are, to some extent, problematic regarding the formation of whiskers.

Whiskers are finest tin needles or tin crystals developing very fast due to material tensions and appropriate ambient conditions in case of pure tin surfaces. Based on their characteristics whiskers can cause short circuits between component pins. Thus, components can be damaged or failure malfunctions can be provoked.
