Abstract
A paste dispenser and a method for controlling the same are disclosed. The paste dispenser includes a stage having a substrate mounted thereon, at least one nozzle dispensing a paste on the substrate by relative movement between the nozzle and the substrate, a measuring means provided at a position facing into an outlet of the nozzle and directly measuring a position of an exchange nozzle, and a controller converting a compensation value in accordance with a displacement of the exchange nozzle based on data measured by the measuring means.
Claims14
A paste dispenser for dispensing a paste onto a substrate, comprising:
- a stage for receiving a substrate;
- a nozzle unit mounted over the stage, wherein the nozzle unit comprises first and second nozzle units, and wherein both the first and second nozzle units are configured to dispense paste onto a substrate on the stage as one of the nozzle unit and the stage are moved relative to the other, and wherein at least one of the first and second nozzle units is movable relative to the other;
- a controller that is configured to control movements of at least one of the first and second nozzle units;
- and
- a measuring unit that is fixed relative to the stage, wherein the measuring unit is configured to determine positions of the first and second nozzle units, and wherein the controller is configured to cause one of the first and second nozzle units to move relative to the other based on the determined positions of the first and second nozzle units.
A paste dispenser for dispensing paste onto a substrate, comprising:
- a stage for receiving a substrate;
- a reference nozzle unit mounted over the stage, wherein the reference nozzle unit is configured to dispense paste onto a substrate on the stage as one of the reference nozzle unit and the stage are moved relative to the other;
- a second nozzle unit mounted over the stage, wherein the second nozzle unit is configured to dispense paste onto a substrate on the stage as one of the second nozzle unit and the stage are moved relative to the other, wherein the second nozzle unit is movable relative to the reference nozzle unit;
- and
- a measuring unit configured to sense positions of the reference nozzle unit and the second nozzle unit;
- and
- a controller that receives a signal from the measuring unit that is indicative of the positions of the reference and second nozzle units relative to the stage, wherein the controller causes the second nozzle unit to move relative to the reference nozzle unit based on the sensed positions of the reference and second nozzle units.
