Abstract
A strap spring for insertion into a circuit board for securing a heat sink to an electronic device is disclosed that has a body portion having two ends and a contact section and one or more engaging sections extending from said ends. The ends are inserted into an aperture in the circuit board and an aperture in the heat sink to anchor the circuit board to the heat sink. Electronic assemblies comprising a circuit board having a microprocessor and a heat sink having a surface larger than the microprocessor are also disclosed in which a strap spring is disposed on a side of the circuit board opposite the heat sink, and the strap extends through the circuit board to engage the heat sink.
Claims7
