Abstract
A method for improving the morphology of drops ejected from inkjet dispensers results in a more accurate and repeatable process. The method involves shifting the dwell time from one corresponding to the first harmonic of the dispenser to a higher harmonic, for example, the third harmonic.
Claims2
A method for improving the morphology of drops dispensed from an inkjet dispenser, the method comprising the steps of:
- establishing a dwell time corresponding to the first harmonic operating region of an inkjet dispenser;
- calculating a dwell time corresponding to the third harmonic operating region of the inkjet dispenser by multiplying the dwell time corresponding to the first harmonic operating region of the inkjet dispenser by a factor of three;
- adjusting the dwell time corresponding to the third harmonic operating region of the inkjet dispenser to maximize drop mass and produce consistent drop morphology;
- and
- reprogramming the inkjet dispenser to operate at the adjusted dwell time.
