MOUNTING APPARATUS FOR BRACKET OF HEAT SINK

摘要

A circuit board assembly includes a circuit board and a bracket of a heat sink. The bracket of the heat sink includes a pair of first securing feet and a pair of second securing feet opposite to the pair of first securing feet. A pair of first securing members is secured to the circuit board. A pair of second securing members is secured to the circuit board facing the pair of first securing members. The pair of first securing members includes a pair of elastic pieces which faces the pair of second securing members. The pair of first securing feet abuts against the pair of elastic pieces to elastically deform the pair of elastic pieces. The pair of elastic pieces exerts force on the bracket to push the pair of second securing feet to abut against the pair of second securing members.
