ABSTRACT:
A method of abrading and simultaneously coating at least one surface of an article, particularly a circuit board assembly. The method comprises introducing abrasive particles into the compressed gas supply of a spray gun. The resulting gas stream with entrained abrasive particles is transported to and emitted from at least one spray nozzle of the spray gun where it is directed to the surface of the article with a film-forming coating composition stream also directed to and emitted from at least one nozzle of the spray gun. The abrasive particles can be simultaneously sprayed along with the optional coating composition onto the surface (these abrasive particles being microballoons in the case of a circuit board assembly). The surface is abraded while the coating is being applied. The resulting coating is substantially free of abrasive articles and has good adherence to the surface. The abrasive-containing compressed gas stream cleans and abrades the surface of the article, thereby preparing the surface to receive a coating.
