Abstract:
A printed circuit board assembly comprising:a printed circuit board having a heat transfer region and at least one via in thermal communication with the region that transfers heat to the at least one region; a heat generating component mounted on the printed circuit board so as to be in thermal communication with the at least one via wherein the heat generated by the component is transferred by the via to the region; at least one transfer zone, formed on a surface of an edge of the printed circuit board, in thermal communication with the region that enables the heat transfer from the region; a chassis having: a rail in thermal communication with the at least one transfer zone so as to receive heat from the heat generating component the chassis dissipating heat received from the region via convection; a first shell half positioned above the printed circuit board; a second shell half positioned below the printed circuit board; and a rail lock that biases the first shell half toward the second shell half securing the printed circuit board and the rail there between.
