摘要： A system (100, 150, 160, 202) for delivering material (104) onto a substrate (106) includes a jetting system having a reservoir (102) containing the material (104) and the reservoir (102) includes a nozzle (108) through which the material (104) is expelled from the reservoir (102). An arcuate section (110, 110 ) is positioned between the reservoir (102) and the nozzle (108). The material (104) is configured to travel from the reservoir (102), through the arcuate section (110, 110 ), and through the nozzle (108). The system(100, 150, 160, 202) also includes a means for applying pressure (112, 208) on the material (104) contained in the reservoir (102), wherein the material (104) is expelled from the reservoir (102) through application of pressure by the means for applying pressure (112, 208) to thereby create a column of the material (118) from the nozzle (108). A means for producing pressure modulations (122, 214) is located proximate the nozzle (108) and is configured to substantially regulate formation of droplets (120) from the column of the material (118). In addition, the system (100, 150, 160, 202) includes a charging ring (126, 216) configured to induce an electrical charge to selective ones of the droplets (120) as they pass through the charging ring (126, 216). One or more deflection plates (128, 218) are also included for altering a trajectory of the charged droplets (120).
