ABSTRACT:
The method for dispensing liquid on a substrate includes providing a plate (108) having a plurality apertures (110). These apertures (110) conform to the pattern of a plurality of pads (104, 106) of at least one component of a substrate (102). The apertures (110) are filled with the liquid to be dispensed, and are then aligned with the plurality of pads (104, 106) on the substrate (102). The liquid is simultaneously transferred out of the apertures (110)and onto the plurality of pads (104, 106) using a blower (112 ).
