Abstract
To restrain detachment of heat sinks from printed circuit boards (PCBs) or the components mounted on such boards, a body is attached to the board and extends above the tops of the heat sinks. Above each heat sink, three sides of a rectangle are cut from the body, leaving one side uncut. The tongue thus formed is curved downwards to form a spring which bears against the top of the heat sink to protect the heat sink from disengagement. The body is formed with vertical ends or legs having outward bent feet which are secured to the PCB by screws or other fasteners or are fit through slots in the PCB. A slanted tongue may also be cut from the body to engage an upper corner of a heat sink to restrain the heat sink from lateral movement relative to the PCB.
