Abstract:
1. A printed circuit board thermally coupled to an electronic device, comprising: a multi-layered circuit layer extending horizontally; a binding pad disposed on and in contact with an upper surface of the circuit layer and coupled to the electronic device; a first ground disposed on a lower surface of the circuit layer and arrayed in an area heated at the time of thermal binding; a second ground, connected to the first ground and disposed on and in contact with the upper surface of the circuit layer and arrayed adjacent to the binding pad; and a via directly connecting the first ground to the second ground, wherein: a portion of the first ground is arrayed on an opposite side of the circuit layer to a side on which the binding pad is disposed, such that a horizontal planar position of said portion of the first ground corresponds to a horizontal planar position of the binding pad and that said portion of the first ground covers and is superimposed on at least a portion of the binding pad.
