Circuit board mounting apparatus

A circuit board mounting apparatus, comprising:

• a chassis comprising a side plate defining a latching hole and at least one slide slot;
• and
• 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 left from a front end of the neck, the front side of the circuit board defining a cutout, a cantilever extending from an end wall bounding the cutout, a hook protruding from a front side of the cantilever and 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, the cantilever resists 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.
