METHOD AND APPARATUS FOR AUTOMATICALLY ADJUSTING DISPENSING UNITS OF A DISPENSER

摘要

A dispensing apparatus includes a frame having a gantry configured to provide movement in the X axis and Y axis directions, and first and second dispensing units coupled to the gantry and configured to dispense material onto a substrate. The second dispensing unit is coupled to the gantry by an automatic adjustment mechanism. The dispensing apparatus further includes a controller configured to control the operation of the gantry, the first dispenser, the second dispenser, and the automatic adjustment mechanism. The automatic adjustment mechanism is configured to move the second dispenser in the X axis and Y axis directions to manipulate a spacing between the first dispensing unit and the second dispensing. Methods of dispensing material on the substrate are further disclosed.

1. 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 dispensing units over the first and second electronic substrate patterns with a gantry configured to move the first and second dispensing units in an X axis direction and a Y axis direction; aligning the first electronic substrate pattern with the first dispensing unit and the second electronic substrate pattern with the second dispensing unit with an automatic adjustment mechanism configured to move the second dispensing unit in the X axis direction and the Y axis direction a predetermined distance from the first dispensing unit; dispensing material from the first dispensing unit at desired locations on the first electronic substrate pattern; and dispensing material from the second dispensing unit at desired locations on the second electronic substrate pattern.
