Circuit board mounting apparatus

A circuit board mounting apparatus, comprising:

• a chassis comprising a side plate defining at least one slide slot and a latching hole;
• a circuit board, at least one substantially L-shaped latch protruding from a front side of the circuit board, each of the at least one latch comprising a neck connected to the front side of the circuit board, and a latching portion extending leftward from a front end of the neck;
• and
• a mounting member mounted to the circuit board and adjacent to the front side of the circuit board, the mounting member comprising a resilient arm and a hook protruding from a front side of the resilient arm, the hook comprising an engaging surface facing rightward;
• wherein the at least one latch extends through the at least one slide slot and slides to allow the neck to abut against a portion of the side plate bounding a left end of the slide slot, and to allow the latching portion to engage with a front side of the side plate, and meanwhile, the resilient arm biases the hook to engage in the latching hole, to allow the engaging surface of the hook to abut against a portion of the side plate bounding a right end of the latching hole, to perpendicularly fix the circuit board to the side plate.
