Heat sink having protective device for thermal interface material spread thereon

摘要

A protective device (10) comprises a cap (100) and a strap (120) connecting with the cap (100). The cap (100) defines a cavity (102) which is adapted for accommodating thermal interface material (300) spread on a bottom surface (204) of a heat sink (200). At least three sides of the heat sink (200) are encircled by the strap (120), thereby the cap (100) is firmly attached to the heat sink (200) via the strap (120).
