A dispensing apparatus for dispensing viscous material on an electronic substrate includes a frame, a support coupled to the frame to receive electronic substrates, a first dispensing unit configured to dispense viscous material, a second dispensing unit configured to dispense viscous material, and a gantry coupled to the frame. The gantry comprises a first Z drive mechanism configured to support the first dispensing unit and lower the first dispensing unit toward a first electronic substrate pattern when performing a dispense operation, and a second Z drive mechanism configured to support the second dispensing unit and lower the second dispensing unit toward a second electronic substrate pattern when performing a dispense operation. The second Z drive mechanism is capable of being adjusted relative to the first Z drive mechanism a predetermined distance. A controller is configured to control a dispense operation of the first dispensing unit on the first electronic substrate pattern and a dispense operation of the second dispensing unit on the second electronic substrate pattern. Methods of dispensing viscous material are further disclosed. |
