This device can be used to place adhesives between the conductive lands of a printed circuit board to adhere "chip type" electronic components between the conductive lands of the board. The dispenser comprises an outer cylinder carried in a support housing for movement toward and away from the board, the outer cylinder carries an adhesive metering device which places a dot of adhesive on the board.
