(May 19, 2008) CARLSBAD, Calif. — Asymtek, a Nordson company, introduced the Spectrum S-822 dispensing system with dual-shuttle stages to increase the productivity achieved in chipscale package (CSP) underfill and other advanced electronics applications. The S-822 is a stand-alone system with controlled precision dispensing capabilities and many proprietary Asymtek processes.
The S-822 system allows parallel processing on two shuttle stages for continuous dispensing, which is designed to reduce lost time in non-dispensing activities such as pre-heating parts and substrate loading and unloading. 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 saves time when a pre-heat process is required and minimizes manufacturing cost per square foot, according to the company. Options include choice of impingement or contact-heated stations for one or both shuttle stages.
Asymtek's proprietary "Jet-on-the-Fly" dispenses lines of dots without stopping, which reduces time compared to conventional needle dispensing. "Calibrated Process Jetting" uses weight control to reportedly ensure volumetric repeatability and optimizes line speed for Jet-on-the-Fly operations. "Dynamic Dispense Control" offers control parameters through closed-loop servo technology so the user can specify different acceleration and deceleration values for the valve or pump, tailoring each dispense shot for speed, accuracy, and yield. "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 user-intuitive application software. Once an operation is programmed, it can be transferred to any Asymtek system that uses Fluidmove. 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 comes with ESD glass and has passed all EMC testing for CE certification.
