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.

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 is used to identify and compensate for errors created by changes in the relative positions of a deposition unit and a vision system of a dispenser. The method includes calibrating the vision system, dispensing a pattern of features over a working area, moving the vision system over a deposition location to locate a deposition, obtaining an image of the deposition, tagging data associated with the image, calculating a relative distance between the deposition unit and the vision system, storing correction data with spatial location in a file for later use, and using the stored data to make small corrections prior to dispensing additional material.

Abstract: A system for dispensing material on a substrate includes a dispensing unit having a dispensing piston. The dispensing piston is pneumatically driven from a first lower position to a second upper position. The system further includes a solenoid valve coupled to the dispensing unit, with the solenoid valve being configured to control air flow to and from the dispensing piston. The solenoid valve includes a solenoid coil and an amplifier connected to the solenoid coil. The system further includes a controller coupled to the amplifier, with the controller being configured to generate a command signal to the amplifier to control current in the solenoid coil.

Abstract: A method of controlling a dispensing unit is used to dispense material on a substrate. The method includes connecting a solenoid coil of a pneumatically-driven pump to an amplifier output of a dispensing system, and driving the solenoid coil with the amplifier to a cause the pneumatically-driven pump to dispense material on a substrate. The method further may include commanding an idle current to flow in the solenoid coil during periods of inactivity. The idle current may be sufficient to cause warming of the solenoid coil, yet not sufficient to activate the solenoid to an engaged position. The method further may include commanding a first current level to flow in the solenoid coil to rapidly activate the solenoid, and commanding a second current level to flow in the solenoid coil after the solenoid is activated.
