Measuring electrode for monitoring electroless metal deposition baths - has small surface curvature or area and gives clear deposition assessment

摘要

For monitoring electroless metal deposition baths by measuring voltage between a measuring electrode in the bath and a reference electrode, the measuring electrode has a small surface curvature, through use of wires of small dia., or small surface areas in contact with the metallising soln., through use of small dimension conductor structures on a dielectric substrate. Pref. dia. or width is between 50mm and 2mm.. ADVANTAGE - Gives clear and sensitive assessment of deposition characteristics.
