A mounting clip for securing a heat sink to a device package is secured to the heat sink by forming a groove in the heat sink, positioning the central body portion of the clip in the groove and deforming the wall of the groove to trap the clip in the groove. The clip is an elongated body with ends extending from the axis of its central body. The ends may be trapped or hooked in appropriate receivers on a frame or socket holding an electronic device package to secure the heat sink adjacent the device package.

Spring clamp and heat sink assembly

Two or more bodies of sheet-like material are secured together with a single rivet-like fastening device which has an expanded head, a shank extending from the expanded head and a chamfer at the junction of the expanded head and the shank having a radius which is larger adjacent the head and which has bosses extending radially therefrom. An aperture is formed in the first body of material which substantially conforms to the radial dimensions of the shank and the shank is inserted into the aperture. A shaped aperture having radial dimensions which cooperate with the shank to define voids adjacent the shank is formed in the second body of material and the shank inserted into the shaped aperture. The shank is then axially compressed to force the first body over the chamfer and deform part of the first body into the voids in the second body, thus locking the first and second bodies together.
