Asymtek’s Spectrum S-822 Speeds Fluid Dispensing Throughput with Dual-Shuttle Configuration

Asymtek, a Nordson company and leader in dispensing, coating, and jetting technologies, introduces the Spectrum™ S-822 dispensing system with dual-shuttle stages to increase the productivity achieved in such processes as chip scale package (CSP) underfill and other advanced electronics applications. The S-822 is a standalone system that offers the controlled precision dispensing capabilities and many of the patented processes found in Asymtek’s advanced in-line systems.

The S-822 system allows parallel processing on two shuttle stages for continuous dispensing, which significantly reduces 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 lowers cost-of-ownership without adding another full system to the production line, minimizing manufacturing cost per square foot. Options include choice of impingement or contact heated stations for one or both shuttle stages.

Asymtek’s patented Jet-on-the-Fly dispenses lines of dots without stopping, which significantly reduces time compared to conventional needle dispensing. 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 so the user can specify different acceleration and deceleration values for the valve or pump, allowing for each dispense shot to be optimized 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 (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 wide range of fluids, processes, and substrates and easily integrates with most jets, pumps, and valves from Asymtek. The system is easy to use and maintain and comes with ESD glass and has passed all EMC testing for CE certification.
