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.
