Charged Droplet Behavior on Drop on Demand (DoD) Electrohydrodynamics (EHD) inkjet Printing

Hadi Teguh Yudistira, Vu Dat Nguyen, Doyoung Byun

Abstract

Inkjet printing technology has got attention for fabrication process. Electrohydrodynamics (EHD) inkjet printing can produce tiny droplets. There are many charge droplets that were produced by EHD inkjet printing for several seconds. Charge accumulation was exist on substrate. Due to electric field force and charge interaction force, droplet may not go straight to substrate. Droplet may get reflection, deflection or retract to meniscus which make problem in EHD inkjet printing.
