Asymtek launches new high-speed DispenseJet® DJ-9000 jet
Feb 26, 2004
Asymtek announces the release of its new DispenseJet® DJ-9000 jet for precise, high-speed delivery of a wide variety of fluids including underfill, surface mount adhesive, encapsulants, conformal coatings, UV adhesives and silver epoxy.
Based on the company’s award-winning DJ-2100 series, the DJ-9000 is a new generation jet that is faster, easier to clean, and delivers the capabilities needed for today’s most advanced production requirements.
The DJ-9000 is ideal for stacked die and densely packed boards. It jets in tight spaces as small as 200 micrometers, and creates fillet wet-out widths as small as 300 micrometers on the dispensed side of the die. The fluid exits the nozzle in a 100 micron diameter stream, which provides the highest flow rate in tight spaces. The DJ-9000 jets fluid either as discrete dots or a rapid succession of dots to form lines. Jetting "on the fly" provides up to 400% greater throughput over needle dispensing.
The Jet achieves dot diameters as small as 0.33 mm, and shot volumes as small as 3.6 nanoliters. Jetting breaks through many of the barriers of traditional needle dispensing to deliver speed, quality and low cost of ownership, and has proven to be one of the best ways to dispense multiple fluids. The DJ-9000’s benefits include:
Speed: high flow rates over 120 mg/second (for underfill materials); high shot rate up to 200 dots per second; no Z-axis motion; jets "on the fly" with no stopping required between dots; less height sensing required; no needle backtracking to prevent fluid stringing.
Quality: high wet-dispense accuracy; smaller wet-out areas; round and uniform dots; improved line quality and line knit. Common problems such as bent needles, component damage, and dripping are eliminated.
Low Cost of Ownership: less waste of fluid due to its small, wetted path; cleaning in 10 minutes or less without tools; consumable parts are less expensive; no required under-board support; one model handles multiple applications.
