er). The PC-600 Carrier feed rate should be about 0.2 to 0.5 mL/amp. hr. The pulse waveform should be set at 40 msec forward; 2.3 msec reverse and a 2 to 1 reverse current ratio. Plate a test panel and obtain cross-section results to be sure the optimum performance is obtained before starting production. Some plating tankorboard designs may require special waveformsorbrightener concentrations in order to obtain optimum results.
