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
