The Asymtek Spectrum S-820 dispensing system is designed for batch processing in semiconductor packaging, such as underfill, cavity fill, die attach and encapsulation. It provides exceptional dispensing accuracy, and is ideal for batch production, new product development and labs. The closed-loop system performs with a wide range of fluids, processes and substrates used in semiconductor packaging and assembly. The company’s process-control functions are incorporated, bringing premium features to this machine. Jet on the fly is a feature that allows dispensing lines of dots without stopping. Time is significantly reduced when compared to traditional needle dispensing. The calibration uses weight control to ensure precise volumetric repeatability and optimize speed. Dynamic control offers precise and flexible verification by closed-loop technology. With encoders and feedback from the dispensing pump, 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 automated calibration to deliver fluid amounts consistently throughout production.
