We are currently using Duriod 6002/6010 type PWB's on one of our products and are having problems cleaning the PWB's after soldering and assembly operations. Removal of fluxes and the cleaning fluid (Axarel) from this very hygroscopic material has been difficult inspite of using the Manufacturers recommended process. Any information or sources of potential information relating to resolving this situation would be appreciated. [log in to unmask]
