Keywords: Asymtek, Surface mount technology

Asymtek has introduced a 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.

Ideal for stacked die and densely packed boards, the DJ-9000 jets in tight spaces as small as 200 μm, and creates fillet wet-out widths as small as 300 μm on the dispensed side of the die. The DJ-9000 dispenses fluid either as discrete dots or a rapid succession of dots to form a 100 micron (4 mil) diameter stream of fluid from the nozzle. Dot diameters as small as 0.33 mm and shot volumes as small as 3.6 nl can also be achieved. 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 many fluids.

The DJ-9000’s benefits include the following.

Speed. High flow rates of up to 50 mg/s (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, chipped die, warpage effects and dripping are eliminated.

Low cost of ownership. Less waste of fluid due to its small, wetted path; cleaning in 10 min or less without tools; consumable parts are less expensive; no required under-board support; one model handles multiple applications.
