Asymtek's New DispenseJet DJ-9500 is up to Ten Times Faster than Needle Dispensers in High-Volume Underfill and LED Silicone Applications

Jul 24, 2008

Asymtek, a Nordson company (Nasdaq:NDSN) and leader in dispensing, coating and jetting technologies, introduces 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 wide variety of fluids up to 10 times faster than existing needle type dispensers, even with abrasive fluids. The new design enables compatibility with a wider 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 5 to 10 times longer than other tested needle assemblies. Enhanced temperature controls maintain 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” (U.S. Patents 5,711,989 and 5,505,777) “dot on dot,” (U.S. Patent 5,747,102) and Calibrated Process Jetting™ (U.S. Patent 6,173,864).
