Abstract
Moisture condensed on a circuit board can cause dendritic growth which can short out a circuit. Such sensitive areas are protected from condensation by filling cavities in an assembly with insulating material to exclude moisture bearing air. Foamed plastic is molded or stamped into shapes which conform to a cavity and are inserted into the assembly. The plastic body is held against the circuit board to preclude condensation on the board. Adhesives and sealants are not required.
