Abstract
A fastener assembly for securing a heat sink to a printed circuit board, includes a sleeve, a bolt inserted into the sleeve and a resilient component surrounding the bolt. The sleeve comprises a hollow body, a bottom plate at a bottom thereof and an engaging cylinder extending downwardly from the bottom plate. The engaging cylinder has inner thread and a deformable latching protrusion projecting radially outwardly. The bolt includes a shaft, a head and a threaded part for threadedly engaging with a retainer of the printed circuit board. The head is received in the sleeve above the bottom plate. The shaft is received in the through hole of the sleeve whilst the threaded part is held beneath the engaging cylinder of the sleeve. The resilient component is compressed between the head of the bolt and the bottom plate of the sleeve.
