Claim 8

A spring clip for attaching an electronic device package to a heat sink comprising a unitary body defining: (a) a base portion having first and second ends extending in opposite directions from and substantially coplanar with a substantially flat face; (b) a spring portion extending from said base portion intermediate said first and second ends and projecting in a direction opposite said substantially flat face; (c) a finger portion extending from said spring portion and adapted to mate with an electronic device package and urge the device package into contact with a heat sink; and (d) an insulating material secured to said finger portion; wherein said insulating material is an insulating cover which defines a pocket and said finger portion of said spring clip is secured within said pocket.

Claim 9

The combination comprising: (a) a heat sink having a first surface, a second surface and a shoulder extending from the plane of said second surface with a groove in said shoulder substantially forming an extension of said second surface; (b) an electronic device package having a face positioned adjacent said first surface; and (c) a spring clip securing said device package adjacent said first surface comprising a unitary body defining: (i) a base portion having first and second ends extending in opposite directions from and substantially coplanar with a substantially flat face positioned adjacent said second surface with said first end positioned in said groove; (ii) a spring portion extending from said base portion intermediate said first and second ends; and (iii) a finger portion extending from said spring portion urging said device package into contact with said first surface.

Claim 10

The combination comprising: (a) a heat sink having a first surface, a second surface and a shoulder extending from the plane of said second surface with a groove in said shoulder substantially forming an extension of said second surface; (b) an electronic device package having a face positioned adjacent said first surface; and (c) a spring clip securing said device package adjacent said first surface comprising a unitary body defining: (i) a base portion having first and second ends extending in opposite directions from and substantially coplanar with a substantially flat face positioned adjacent said second surface with said first end positioned in said groove; (ii) a spring portion extending from said base portion intermediate said first and second ends; and (iii) a finger portion extending from said spring portion urging said device package into contact with said first surface.

Claim 11

The combination defined in claim 5 wherein said first surface and said second surface lie in substantially parallel planes.

Claim 12

The combination defined in claim 5 wherein said first surface lies in a plane which is substantially normal to the plane of said second surface.

Claim 13

The combination defined in claim 5 wherein said second surface is defined by said shoulder and a second shoulder.

Claim 14
