Abstract
Systems and methods for closed loop fluid velocity control for jetting are disclosed. A method includes dispensing a first volume of viscous fluid from a nozzle of a dispensing device according to a first value of an operating parameter that affects the exit velocity of the first volume. A characteristic of the first volume is measured using a sensor. The characteristic of the first volume is then compared to a range of values to determine whether the characteristic of the first volume is outside of the range. The value of the operating parameter is adjusted to a second value in response to determining that the characteristic of the first volume is outside the range. A second volume of viscous fluid is dispensed according to the second value of the operating parameter. The exit velocity of the second volume is different than the first volume.
