Worked fine for me a few years ago on a deep nickel - gold (hard) line. I used
it to get shorter plating times, less dryfilm attack, a little better
leveling.
Main problem was the variable time of each pulse on the supply was very short
for board plating applications; used the longest pulses I could set & could
have used a little longer. Peak power only allowed one panel at a time too.
