Abstract From the Canadian patent

Dots of adhesive are deposited at selected locations of the surface of a printed circuit board by sensing a reference spacing between an adhesive dispensing nozzle tip advancing toward the substrate and each selected location on the substrate. The advance of the tip is halted at a preferred distance from each selected location. The tip of a vacuum spindle of a pick and place machine is spaced for handling surface mountable device components.
