A method of dispensing viscous material on an electronic substrate, the method comprising: - delivering a first electronic substrate pattern to a dispense position; - delivering a second electronic substrate pattern to a dispense position; - moving first and second dispensers (104, 106) over the first and second electronic substrate patterns (102a, 102b) with a gantry configured to move the first and second dispensing units (104, 106) in an X axis direction and a Y axis direction, the gantry including a first side rail, a second side rail and a beam that extends between the first side rail and the second side rail, the beam being configured to move in the Y axis direction along the first and second side rails (26, 28) to achieve Y axis movement, the gantry further including a carriage mounted on the beam, the carriage being configured to move along the length of the beam in the X axis direction, and to support the first dispenser and the second dispenser; - aligning the first electronic substrate pattern with the first dispenser and the second electronic substrate pattern with the second dispenser with the carriage and an automatic adjustment mechanism configured to move the second dispenser in at least one of the X axis direction and the Y axis direction a predetermined distance from the first dispenser; - capturing at least one image of the first pattern and the second pattern with an imaging system, wherein the second pattern is identical to the first pattern; - adjusting the second dispensing unit automatically relative to the first dispensing unit by the automatic adjusting mechanism, and determining whether the first and second patterns (102a, 102b) are properly positioned to perform simultaneous dispense operations on the two patterns (102a, 102b) based on the at least one captured image of the first pattern and the second pattern, - dispensing material from the first dispenser at desired locations on the first electronic substrate pattern; and - dispensing material from the second dispenser at desired locations on the second electronic substrate pattern, wherein the automatic adjustment mechanism includes a linear bearing secured to the carriage, a mounting block, configured to ride along the linear bearing, coupled to the second dispenser, and a first linear drive motor assembly configured to move the mounting block along the linear bearing. - delivering a first electronic substrate pattern to a dispense position; - delivering a second electronic substrate pattern to a dispense position; - moving first and second dispensers (104, 106) over the first and second electronic substrate patterns (102a, 102b) with a gantry configured to move the first and second dispensing units (104, 106) in an X axis direction and a Y axis direction, the gantry including a first side rail, a second side rail and a beam that extends between the first side rail and the second side rail, the beam being configured to move in the Y axis direction along the first and second side rails (26, 28) to achieve Y axis movement, the gantry further including a carriage mounted on the beam, the carriage being configured to move along the length of the beam in the X axis direction, and to support the first dispenser and the second dispenser; - aligning the first electronic substrate pattern with the first dispenser and the second electronic substrate pattern with the second dispenser with the carriage and an automatic adjustment mechanism configured to move the second dispenser in at least one of the X axis direction and the Y axis direction a predetermined distance from the first dispenser; - capturing at least one image of the first pattern and the second pattern with an imaging system, wherein the second pattern is identical to the first pattern; - adjusting the second dispensing unit automatically relative to the first dispensing unit by the automatic adjusting mechanism, and determining whether the first and second patterns (102a, 102b) are properly positioned to perform simultaneous dispense operations on the two patterns (102a, 102b) based on the at least one captured image of the first pattern and the second pattern, - dispensing material from the first dispenser at desired locations on the first electronic substrate pattern; and - dispensing material from the second dispenser at desired locations on the second electronic substrate pattern, wherein the automatic adjustment mechanism includes a linear bearing secured to the carriage, a mounting block, configured to ride along the linear bearing, coupled to the second dispenser, and a first linear drive motor assembly configured to move the mounting block along the linear bearing.
