Abstract
A retaining clip including a hollow shaft having a first end and a second end. A flange is fixedly attached at the first end of the shaft. The shaft and the flange are integrally formed. A plurality of retention members are resiliently attached to the shaft adjacent to the second end of the shaft. A helically wound spring is carried by the shaft and extends from adjacent to the flange towards the retention member. The retention clip may be used to attach a heat sink assembly to a printed circuit module. Each spring is capable of providing a force to engage the heat sink against the heat generating component with a constant force.
