Abstract: A method for protecting an assembled circuit board by providing a layer of rosin micro-spheres directly on the components to be protected, heating the micro-spheres to a temperature of about 65° C. for a time sufficient to cause the micro-spheres to flow and the rosin to crosslink, and then allowing the board to cool until the rosin returns to its solid state. The rosin micro-spheres may be put onto the board and components by first loading the microspheres onto a transfer tape and then positioning the transfer tape, microspheres down, over the components to be protected. After the rosin is heated the tape may be removed. The method is effective for protecting assembled boards against airborne S to prevent creep corrosion of the copper metallization, and for protecting against Sn to prevent the formation of tin whiskers in tin-plated or soldered lead-free assemblies.
