    摘要： Apparatus and methods for spray coating selected areas of a circuit board with a liquid coating material without coating regions of the circuit board to be left uncoated. In one mode of operation, a bead of liquid coating material dispensed from an elongated nozzle tip is atomized by directing jets of air pressurized against the bead to form a conical, swirling spray pattern which is sprayed on selected areas of a circuit board. In a second mode of operation, the non-atomized bead of liquid coating material dispensed through the elongated nozzle tip is applied on selected areas of the circuit board. In a third mode of operation, jets of pressurized air are directed against the bead of liquid coating material to create a soft swirl pattern, without atomizing the bead of coating material.
