Fluid dispense device calibration
View Patent ↗Systems and methods for calibrating a dispense head to provide substantially uniform droplets on a substrate are described.
1. A method of calibrating a plurality of dispense heads within a fluid dispense system, the method comprising:
positioning a mold within the fluid dispense system, the mold having a substantially planar surface;
altering a voltage applied to the plurality of dispense heads such that for each voltage applied:
dispensing a plurality of droplets of polymerizable material from the plurality of dispense heads on a substrate;
contacting the polymerizable material with the substantially planar surface of the mold and solidifying the polymerizable material to form a patterned layer on the substrate;
measuring a residual layer thickness of the patterned layer;
from the residual layer thickness measured from each voltage applied, determining a desired residual layer thickness such that each dispense head of the plurality of dispense heads dispenses substantially the same volume;
determining the voltage applied associated with the desired residual layer thickness to define a desired voltage; and
updating the plurality of dispense heads to have the desired voltage applied thereto.
2. The method of claim 1 further comprising verifying the desired film thickness is substantially the same for each of the plurality of dispense heads having the desired voltage applied thereto.
