The DispenseJet DJ-9500 high-speed jet integrates with Nordson ASYMTEK dispensing systems, and delivers several benefits leading from patented technologies developed by ASYMTEK’s dispensing applications experts.
The patented “Jet-on-the-Fly” technology (U.S. Patent 5,711,989 & 5,505,777) delivers speed. In operation, the jet “flies” over the part or substrate, and shoots precise volumes of fluid in dots, lines and patterns. High flow rates up to 400 mg/second; high shot rate up to 200 dots per second; no Z-axis motion. Closed-loop fluid heating ensures constant viscosity throughout the fluid path, even at the highest flow rates.
Patented Calibrated Process Jetting (CPJ) (U.S. Patent 6,173,864) closed-loop control maintains consistent dispense volume. High wet-dispense accuracy; smaller wet-out areas; round, uniform dots; improved line quality with no “dog-bones” and improved knit line.
Patented “Dot-on-Dot” process technology (U.S. Patent 5,747,102): Jetting multiple shots in the same location creates large & small dot sizes with a single hardware set. Low cost of ownership: new wear component materials provide 10-times lifetime improvement. Advanced nozzle design further expands the list of compatible fluids and opens the jetting process window. Lines and complex shapes are constructed from adjacent dots. Robust jetting in the most extreme 24/7 production environments, up to 4000 UPH for flip chip underfill. Various configurations are available to meet specific application requirements.
Fluid jetting offers these capabilities beyond traditional needle dispensing:
Jets in tight spaces as small as 175 µm
Small fillet sizes as small as 250 µm
Dot diameter as small as 200 µm
Shot volumes as small as 1.0 nanoliter
Jet nozzle size as small as 50 µm
Slim design increases dispense area
Optional fluid pre-heaters for low- and high-flow rate applications
