The minimum electrical clearance is the minimum spacing allowed between two non-common conductors. It is almost always determined by the design engineer, and is almost always (should be always) documented on the PWB drawing. However, it applies to more than just the distance between traces and solder joints; it is the defined minimum distance between any non-common conductors anywhere on the finished assembly, including the components.
