A computer controlled method for high speed viscous fluid dispensing includes the steps of providing a dot generator and moving the dot generator along at least X and Y axes. The dot generator is controlled to repeatedly eject jets of viscous fluid that break away from the dot generator as a result of their forward momentum and fly to the surface of an adjacent substrate to create dots. The method may further comprise the step of monitoring the size and location of the dots through a vision system. The method may further comprise the steps of assigning dot sizes to specific components based on user specifications or a component library. The method may further comprise the step of optimizing the dot placement paths by aligning the in-line points of dot formation.

[ We claim:] [1.] A viscous fluid dispensing method, comprising the steps of:providing a viscous fluid dot generator for rapidly ejecting jets of a viscous fluid to form dots on a surface of a circuit board substrate positioned adjacent the dot generator without wetting the surface;moving the dot generator transversely adjacent the surface of the substrate; andcontrolling the dot generator so that it repeatedly ejects jets of the viscous fluid during its transverse movement to form dots on the surface of the substrate at a plurality of predetermined locations by pre-triggering the dot generator to eject the jets before the dot generator is directly over the corresponding predetermined locations where the dots are to be formed on the surface of the substrate.
