I would like to find out more about Permanganate desmearing.
What are the bath make-ups (ie. components and concentrations),
process parameters (i.e.. time and temperatures) used for epoxy type
boards.
What are the positive and negative aspects for these materials or
operations?
Are there any good (safe) chemistries other than permanganates for
epoxies, acrylics or polyesters?
Thanks in advance. You can answer me through technet or personally at
