Electronic device with heat sink

摘要

An electronic device includes a circuit board, a tray abutting a bottom surface of the circuit board, and a heat sink attached to a top surface of the circuit board. The circuit board includes a heat generating chip, and a number of through holes defined in the circuit board. The tray includes a number of clipping members. A number of elastic members are attached to the heat sink. The number of clipping members extend through the number of through holes and engaged with the plurality of elastic members, and the number of elastic members are deformable to disengage from the number of clipping members.
