Pure electroplated tin layers naturally develop microscopic, hair-like crystalline structures called "tin whiskers" over time. These whiskers cause short circuits in dense electronic assemblies. Mitigating factors defined in modern processing guidelines include reflow melting (bright-tin processing), implementing nickel underlayers, or deploying mild post-bake steps. 📥 Accessing the Official DIN 50965 PDF
