Abstract:
A low profile heat dissipation and electromagnetic interference shield notebook computer assembly for the motherboard of a notebook computer having a computer base section and a display section, comprising:a motherboard disposed in said computer base section, said motherboard comprising a printed circuit board assembly; a heat generating circuit element mounted on the surface of said motherboard; a heat spreading plate comprising a substantially planar material; a thermally conductive block, said block disposed on the surface of said heat spreading plate; a spacer element, said spacer element disposed between the surface of said motherboard and said heat spreading plate; said spacer element dimensioned to separate the surface of said heat spreading plate and the surface of said motherboard by a predetermined distance sufficient to thermally couple said thermally conductive block and said heat generating circuit element; and a receptacle comprised of an electromagnetic interference (EMI) shield material, said receptacle dimensioned to house said motherboard and having only one open end, said receptacle having one or more grounding tabs coupled to the shield material of said receptacle proximate to said open end of said receptacle; wherein said receptacle is shaped to mate with said heat spreading plate with said one or more grounding tabs electrically coupling said receptacle to said heat spreading plate so as to form an EMI shield enclosure around said motherboard.
