TechNetters:
     
     What experience is out there in cyberspace concerning no-clean fluxes 
     and high voltage power supplies?  Do problems occur when voltages 
     start to exceed 5KV, 10KV, 15KV?  Does anyone have any long term 
     experience or even data they would share?
     
     I am putting these power supplies in flournert and am also getting 
     some clouding due to residues.  Any experience in this area that could 
     be shared.  Has anyone seen any degradation long term of products 
     using this process?
     
     Experimenting with B-24 boards it was found that boards exposed to 
     no-clean flux had a lower voltage breakdown level than normally 
     processed boards (cleaned), or bare boards.  Should this be expected?  
     My thought is no it should not be happening.  Would appreciate some 
     help from you folks.
     
     I would appreciate any and all information provided.  
     
     Ron H.
