The Spectrum S-822 dispensing system from Asymtek allows parallel processing on two shuttle stages for continuous dispensing for reportedly increased productivity in such processes as chip scale package (CSP) underfill and other advanced electronics applications. This stand-alone system offers the controlled precision dispensing capabilities and many of the patented processes found in Asymtek’s advanced in-line systems.

The dispenser’s two stages automatically slide in and out through an opening in the front of the machine, allowing the operator to safely unload and load one side while dispensing continues on the other stage. The S-822’s dual-shuttle configuration is said to save time when a pre-heat process is required, and lowers cost-of-ownership without adding another full system to the production line. Options include choice of impingement or contact heated stations for one or both shuttle stages.

Calibrated process jetting uses weight control to ensure precise volumetric repeatability, and optimizes line speed for Jet-on-the-Fly operations. Dynamic dispense control offers precise and flexible control parameters through closed-loop servo technology. Mass Flow Control uses weight-controlled dispensing and automatic calibration to deliver fluid amounts consistently throughout production.

The system comes with Fluidmove for Windows XP (FmXP) user-intuitive application software. Once an operation is programmed, it can be transferred to any Asymtek system that uses Fluidmove software. The S-822 system performs with a range of fluids, processes, and substrates and integrates with most jets, pumps, and valves from Asymtek. The system is reportedly easy to use and maintain, comes with ESD glass, and has passed all EMC testing for CE certification. Asymtek, A Nordsen Company Carlsbad, CA www.asymtek.com
