Abstract
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 ).

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
91 words
A method for dispensing liquid on a substrate, comprising the steps of: providing a circuit carrying substrate having a plurality of pads: providing a plate above the circuit carrying substrate, the plate having a plurality of apertures which conform to the pattern of the plurality of pads of at least one component on the circuit carrying substrate; providing liquid in the plurality of apertures; aligning the plurality of apertures with the plurality of pads; and transferring the liquid out of the plurality of apertures onto the plurality of pads substantially simultaneously.
Claim 2
Independent Claim
91 words
A method for dispensing liquid on a substrate, comprising the steps of: providing a circuit carrying substrate having a plurality of pads: providing a plate above the circuit carrying substrate, the plate having a plurality of apertures which conform to the pattern of the plurality of pads of at least one component on the circuit carrying substrate; providing liquid in the plurality of apertures; aligning the plurality of apertures with the plurality of pads; and transferring the liquid out of the plurality of apertures onto the plurality of pads substantially simultaneously.
Claim 3
Dependent Claim
23 words
