     Address,
     
     Other than book knowledge, I don't have a lot of hands-on experience 
     with SnPb Oxidation (other than finding it, SEC Test).  Since I am 
     having difficulties in finding a local source to Re-HAL some internal 
     PCBs, I thought I'd approach this matter from another direction.  
     
     Within a FAB Shop, copper oxidation can be easily removed with Sodium 
     Persulfate (Microetch) should this condition present itself.  
     
     What chemicals would you use to remove SnPb Oxidation?
     
     Please advise.  Thank you.
