Abstract:
An insert molded heat sink assembly for removing heat from a semiconductor device package having opposing side wall edges, comprising:a metallic clip member having a main body portion with a first side and a second side opposing said first side; said metallic clip further including a first leg downwardly depending from said first side of said main body and having a free end with an inwardly directed first flange connected to said free end of said first leg; and a second leg downwardly depending from said second side of said main body and having a free end with an inwardly directed second flange connected to said free end of said second leg;a base member of thermally conductive moldable polymer material; said base member having a bottom surface and a top surface; said metallic clip member being embedded within said base member with said first leg and said second leg emanating below said bottom surface of said base member; said base member further including a plurality of integrally formed heat dissipating elements emanating upwardly from said top surface of said base member; said heat dissipating elements being of the same thermally conductive moldable polymer material as said base member;whereby said first leg and said second leg, respectively, embrace the opposing side wall edges of a semiconductor device package to place the bottom surface of said base member into thermal communication with said semiconductor device package.
