The DispenseJet DJ-9500 fluid-jetting valve is suited for high-speed underfill applications and jetting silicone for LEDs. The DJ-9500’s flexible pneumatic design can reportedly jet a wide variety of fluids up to 10 times faster than existing needle-type dispensers, even with abrasive fluids. The DJ-9500 controls fluid breakoff at the nozzle tip for clean and consistent dots and line patterns on the substrate. The new long-life needle assembly lasts five to 10 times longer than other tested needle assemblies. Enhanced temperature controls maintain the fluid at a consistent viscosity for high-throughput applications.
