    Patent number: 6139711
    Abstract: An apparatus for measuring the throwing power of electroplating solutions which provides a nearly linear current density distribution across the panel. The apparatus includes a cylindrical body adapted for rotation about a longitudinal axis thereof, a cylindrical cathode arranged coaxially about a central portion of the cylindrical body, an anode coaxially positioned at a lower end portion of the cylindrical body, a conical shield coaxially arranged around an upper end portion of the cathode; and an annular disk-baffle coaxially arranged around a lower end portion of the cathode. The conical shield and the disk-baffle provide a substantially linear current distribution over the cathode.
