Printed circuit board (PCB)
2013
The utility model relates to a PCB. The front side of the PCB is a component compactly-arranged side, and is equipped with a highly heating component; the back side of the PCB is a non component compactly-arranged side, and equipped with a copper foil area and a jumper wire which are used for heat radiation; the position of the copper foil area corresponds to that of the highly heating component; and the jumper wire is connected with pins of the highly heating component. The copper foil area is arranged at the back side of the PCB at the position corresponding to that of the highly heating component, and heat is rapidly and effectively taken away via the copper foil area; and in addition, the back side of the PCB is equipped with the jumper wire which is connected with the pins of the highly heating component, and the heat of the component can be transmitted to the jumper wire via the pins for auxiliary heat radiation.
