Abstract
A heat sink assembly (100) which has a heat sink clip (20) is provided. The heat sink clip includes a pin (22) and a spring (24) disposed around the pin. The pin has a head (222) and a clamping portion (224) at opposite ends thereof. An abutting portion (226) in the form of an annular flange is formed between the head and the clamping portion. The spring is located between the head and the abutting portion. The pin includes an upper section (22a) and a lower section (22b) having a diameter smaller than that of the upper section. The flange extends radially outwardly from an outer surface of the lower section of the pin. The abutting portion is for engaging with a bottom surface of a heat sink (10) when the clip is mounted to the heat sink.
