Component Tinning and Reballing
January 11, 2023
The phenomenon of tin whiskers in printed circuit board assembly is a failure mechanism associated with electronic devices that use various solder alloys containing low melting point elements such as tin, cadmium, or indium. However, this phenomenon most commonly occurs with tin. Historically, tin whiskers were avoided by adding lead (Pb) to the solder alloy used for component leads or pads, and circuit boards with HASL (hot air solder leveled) finish. However, since lead has been ...
