Nordson ASYMTEK Intros New Dispensing System
High-speed precision dispensing system.
Carlsbad, CA — Nordson ASYMTEK, a Nordson company (NASDAQ: NDSN), has introduced the Spectrum II, the latest iteration of the Spectrum series of high-speed, high-accuracy dispensing platforms that are used in a wide variety of precision dispensing applications in microelectronics and semiconductor manufacturing and MEMS and LED assembly.

According to the company, the Spectrum II S2-900 Series leverages the same small footprint of 600 x 1321mm as the original Spectrum to provide maximum productivity with minimum manufacturing floor space, while improving the precision, accuracy, and speed of the system to rival much larger platforms.

The new Spectrum II system introduces features that enable new levels of precise fluid dispensing; precision Z-axis performance, formerly only offered as an option on the company's large area platform, has been integrated into every Spectrum II system to enable consistent <200µm dots and solder paste line dispensing for MEMS and HDD assembly. Included is tilt jetting capability for precision coating and underfill in hard-to-reach areas, providing up to 30° tilt with most valves. Underfill can get closer to the die edge for tighter keep-out zones.

The system provides automatic adjusting dual simultaneous dispensing, which minimizes downtime and operator intervention by automatically adjusting valve positions for workpiece skew while dual simultaneous valves decrease the cost of units per hour. Higher brightness vision lighting creates increased contrast for difficult applications, improving fiducial find accuracy and consistency. Higher accuracy non-contact laser height sensors improve detection of surface heights and allow tighter dispense gaps for thinner dispense lines.

As an evolution of the popular Spectrum S-920N, the new Spectrum II system maintains all of the benefits of the prior system such as: fids-on-the-fly software for faster fiducial capturing; patented Calibrated Process Jetting (CPJ) for closed-loop dispense repeatability; configurability with single or dual lanes, and up to six heat stations; flexible number of heating zones and optional Controlled Process Heat (CPH).
