This column marks the end of my eighth year of attempting to give straightforward responses to day-to-day issues that arise in the electroplating arena. It is challenging at times but very enjoyable. All of the questions are real. Yes, I do edit if necessary and change people’s initials to help maintain anonymity.

I have learned that certain questions reappear on a regular basis and many problems and questions are easily answered in the format afforded by this column. Those that are not suitable for use in the column are usually handled via direct e-mail and/or phone discussions. Some questions are such that they can only be handled on a consulting basis. I will continue to respond to questions and problems in a timely manner and with information that can help solve your problems.

We are buying new rectifiers for our hard chromium plating line. What should the ripple voltage specifications be for these rectifiers? I.C.


The ripple voltage should be no more than 5% and should be measured in the voltage range that the rectifiers will be used.
