MJ-SF style drop-on-demand single jet dispensing devicesare suited for dispensing droplets of fluids such as adhesives, waxes, polymers and liquid metals at up to 250°C. An integrated orifice and wetted surfaces that are almost exclusively glass make MJ-SF devices extremely robust to aggressive materials, including solders. Orifice diameters of 20-80 um are available, allowing customers to optimize their process by selecting drop volumes with a two order of magnitude range. Fluids with viscosity less than 20 cP and surface tension in the range 20-70 dynes/cm can be dispensed.
Two fluid fitting styles are available: VCO and VCR. The VCO fitting is intended for use with the PH-04 and PH-05 high temperature printhead assemblies. The integrated orifice extends from the housing, allowing visualization of both internal flow and drop formation. Custom, application-specific configurations can also be developed.
