Abstract:
A printed circuit board assembly comprising:a circuit membranes having an extended ribbon cable with a plurality of longitudinally spaced electric contacts; a printed circuit board with a plurality of longitudinally spaced electric contacts corresponding to the electric contacts of the circuit membrane; a cover plate having an arch-shaped bump formed thereon and locked in correspondence to the electric contacts of the circuit membrane and the printed circuit board; and two screws passing through two longitudinally spaced portions of the printed circuit board and screw to the cover plate for fixing the printed circuit board to the cover plate and clamping the ribbon cable between the cover plate and the printed circuit board; the electric contacts of the printed circuit board being in contact with the electric contacts of the circuit membrane, wherein the arch of said arch-shaped bump extends longitudinally to have an apex intermediate the two screws for providing a substantially uniform contact force between the plurality of electric contacts of the printed circuit board and the electric contacts of the circuit membrane.
