Asymtek Launches New High-Speed DispenseJet®
DJ-9000 Jet
Carlsbad, CA - 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 250 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 150 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.
Celebrating 20 years of success in 2003, Asymtek supplies award-winning
automated fluid dispensing systems to customers worldwide. Specializing
in semiconductor, surface mount, and electronics packaging applications,
they are committed to providing total dispensing solutions and local
support. Find out more on their Web site at: http://www.asymtek.com.
