Abstract: Tin a metal not at all uncommon in electronics has had a re-birth in it a usefulness, this time as a final solderable finish for printed circuit boards. Tm has a long history with the electronic industry, Exposed surfaces of tin produce a stable self-protecting stannous oxide coating. These surface oxides can be easily removed with a no-clean solder flux or paste allowing for excellent soldering of the surface. The majority of solder alloys today use tin as its primary metal. Tin has good electrical properties and is easy to apply. It is relatively inexpensive and its supply is readily available.
