Hi Syd, A number of years ago I read in a H-P Lab Notes publication that a mix of alcohol and houshold ammonia was ideal for super cleaning boards. I think the ammonia was present in 20% concentration. From experience I can tell you that ethyl acetate is a far better solvent than alcohol to remove most organic solder fluxes. Its considerably less toxic than the trichloroethylene that was used for years as a flux remover and degreaser. Only problem with it is you must be sure it doesn't dissolve any plastic component coverings! With both the ammonia and the ethyl acetate one must use adequate ventilation.
Hope this helps. Chuck Eisnor "Syd Levine (AnaLog)" wrote: > I am working on a high voltage shunt regulator design where contamination on > the circuit board is causing problems.
