ABSTRACT:
By sealing the periphery of a printed circuit board, the previously exposed edges of the board are substantially prevented from moisture wicking. This sealing of the periphery can be made concurrently with the plating of through-holes on the board. With this process, current leakage paths due to board moisture wicking within the board is significantly reduced.
