ASYMTEK: Fluid Jetting Valve

August 13, 2008

This company, a leader in dispensing, coating and jetting technologies, has introduced its new DispenseJet® DJ-9500 fluid jetting valve for high-speed underfill applications and jetting silicone for LEDs. The DJ-9500’s flexible pneumatic design can jet a variety of fluids up to 10 times faster than existing needle-type dispensers, even with abrasive fluids. The new design enables compatibility with a range of fluid types, and opens the process window to allow a robust jetting solution. DJ-9500 users will benefit from improved fluid control, better repeatability, increased flexibility and a lower cost of ownership.

The DJ-9500 controls fluid break-off at the nozzle tip for clean and consistent dots and line patterns on the substrate. Because the DJ-9500’s hardware lasts longer and offers better fluid control, a lower cost of ownership is achieved. The new long-life needle assembly lasts five to 10 times longer than other tested needle assemblies. Enhanced temperature controls keep the fluid at a consistent viscosity for high-throughput applications.

Jetting is an automated, non-contact process that dispenses fluids quickly, cleanly, accurately and reliably into places where other dispensing methods can’t reach. The DJ-9500, like Asymtek’s award-winning DispenseJet DJ-9000, features Asymtek’s patented “jetting-on-the-fly,” “dot on dot” and Calibrated Process JettingTM.
