Abstract
The present disclosure provides a printed circuit board with a plated through hole. The through hole covered by a solder pad at both ends of the through hole. At least two pins are plugged into the through hole, one of which with its head end being thermal contacted with one of the solder pads. Another pin's head end being thermal contacted with the other solder pad. The at least two pins are thermal contacted with one another. Thermal dissipation rate is increased with the structure of the through hole.
