Abstract: 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.

Abstract: A method of dispensing material includes delivering an electronic substrate to a dispense position. The electronic substrate has at least two identical patterns and at least two fiducial marks. The method further includes capturing at least one image of the at least two fiducial marks provided on the electronic substrate, analyzing the at least one image to determine a position of the electronic substrate in X axis, Y axis and theta directions, calculating a rotational angle of the electronic substrate, and rotating a dispensing pump array to match an angle of the electronic substrate. Alternatively, the electronic substrate can be rotated to match an angle of the dispensing pump array.
