Whisker (metallurgy) - Wikipedia

Metal 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.

Tin (Sn) - Chemical properties, Health and

Tin in the environment Tin oxide is insoluble and the ore strongly resists weathering, so the amount of tin in soils and natural waters is low. The concentration in soils is generally between the range 1-4 ppm but some soils have less that 0.1 ppm while peats can have as much 300 ppm.

Lecture 1 Corrosion: Introduction Definitions and Types

Dry corrosion occurs in the absence of aqueous environment, usually in the presence of gases and vapours, mainly at high temperatures. Electrochemical nature of corrosion can be understood by examining zinc dissolution

Connector Design/Materials and Connector Reliability

For tin finishes mechanical displacement of the tin oxide is required and mechanical stability of the interface must be maintained to minimize the potential for reoxidation.
