Heat sinking pad and printed circuit board

摘要

The present invention relates to a heat sinking pad and a printed circuit board. The surface of the heat sinking pad on which electronic components are placed comprises a solder loading area and a solder non-loading area, wherein the solder loading area is used for being coated with solder; and the solder non-loading area comprises heat collection passages for collecting heat on the heat sinking pad and heat dissipation passages communicated with the heat collection passages. Openings of the heat dissipation passages are positioned at edges of the heat sinking pad so as to discharge the heat collected by the heat collection passages to the outside of the heat sinking pad. The heat dissipation to the edges of the heat sinking pad along the heat collection passages and the heat dissipation passages is faster than along the solder loading area, so the heat sinking pad has higher heat dissipation speed.
