Patent ID: 7059844

Claim:
A method for the manufacture of a housing having a housing portion adjacent a printed circuit board for accommodating electronic functional elements ( 2 ), comprising: forming a screening seal ( 8 ; 8 ′) to fill a gap between said housing part and said printed circuit board, said seal being made from an electrically conductive elastic plastic material, said electrically conductive elastic plastic material including a silicon polymer, said forming including ejecting said polymer in a pasty initial state with a pressure nozzle and passing said pressure nozzle over one of said housing portions that is to be sealed, so that said polymer is deposited directly on said one of said housing portion ( 3 a ) and said printed circuit board, to form said screening seal with a predetermined profile ( 8 ; 8 ′) without a molding tool; and allowing said screening seal to cure on said one of said housing portion and printed circuit board wherein said screening seal adheres to a surface of said one of said housing portion and said printed circuit board in such a manner that the screening seal maintains its electrical and sealing characteristics even after repeated opening of the housing.
