Method and system for shielding an externally mounted circuit board from electrostatic discharge and mechanical damage while allowing for heat exchange from heat-producing components of the circuit board through the circuit board shield into an external environment

摘要

Method and system for shielding a circuit board from electrostatic discharge and from mechanical damage. A circuit board shield of dimensions roughly equivalent to those of the circuit board that the circuit board shield is designed to protect is manufactured to contain apertures complementary in shape, size, and position to heat-producing components affixed to the surface of a circuit board. When the circuit board shield is placed on top of the circuit board, the heat-producing components of the circuit board remain exposed to an external environment via the apertures, while other parts of the circuit board are protected from electrostatic discharge and mechanical damage by the overlying circuit board shield.
