Abstract
A mask for protecting edge conductors of printed circuit boards from the spray coating which is sprayed on the board. The mask is molded from a soft silicone-based-elastomer material in a configuration which presents a sharp sealing edge and a large interior angle adjacent the seal which effectively limits migration due to capillary action.
