Abstract:
A combination comprising:an electronic assembly including a heat sink, a chip assembly, and a circuit board, said heat sink having a first and a second heat sink aperture formed therethrough, said circuit board having a circuit board contact side and a first and a second circuit board aperture formed therethrough, said heat sink comprising a substantially planar heat sink contact side and having a surface larger than at least a portion of said chip assembly, said first heat sink aperture in registration with said first circuit board aperture, said second heat sink aperture in registration with said second circuit board aperture, said chip assembly including a first contact side that contacts said heat sink contact side and a second contact side that is opposite said first contact side and that contacts said circuit board contact side; anda strap spring including a body portion and a first and a second spring arm, said first and said second spring arm extending from said body portion, said first spring arm defining a first end and said second spring arm defining a second end, said first spring arm end extending through said first circuit board aperture and through said first heat sink aperture, said second spring arm end extending through said second circuit board aperture and through said second heat sink aperture, said body portion urging against a side of said electronic assembly, each one of said first end and said second end urging against an opposing side of said electronic assembly to couple together said heat sink, said chip assembly, and said circuit board, whereby said circuit board is not exposed to bending moments by said spring arm ends.
