ABSTRACT:
A hybrid base plate and electronic circuit board is disclosed for use in the low profile disk drives as used in computers. The hybrid base plate/circuit board is fabricated of a rigid metal insert serving as the base plate and an electronic circuit board, provided with an aperture configured to mate with the perimeter of the metal base plate. The metal base plate is electrically connected to the circuit board to provide grounding; and the circuit board provides support to the base plate, thus permitting the elimination of one thickness of the base plate and the separate circuit board as previously used in disk drives.
