Abstract
A method of providing environmental protection to an electronic component includes placing an electromagnetic shield having at least one cavity in contact with a circuit board having electrical components thereon so as to substantially enclose at least a first compartment between the circuit board and the shield, the shield includes at least one entry hole connecting to the first compartment. A conformal coating is applied by introducing the conformal coating into the first compartment through the entry hole while holding the shield in contact with the circuit board so that the coating is applied to the exposed portions of the circuit board within the compartment, but not applied to portions of the circuit board contacted by the shield. An electrically conductive gasket may be positioned between and in contact with both the circuit board and the shield before the applying of the conformal coating.
