S-820 Precision Batch Semiconductor Dispenser

S-820 Precision Batch Semiconductor Dispenser

The Spectrum™ S-820 Series system is designed for batch production of advanced dispensing applications, including underfill, cavity fill, die attach, and encapsulation. The S-820 provides advanced dispensing process capability in an affordable package, and is ideal for labs, batch production, and new product development.

The S-820 performs with a wide range of fluids, processes and substrates used in semiconductor packaging and assembly. It easily integrates with most Nordson ASYMTEK jets, pumps, and valves, including the DispenseJet® DJ-9500 and NexJet® System.


Nordson ASYMTEK’s advanced process control capabilities have been incorporated into the S-820 platform, bringing premium features to this batch system:

  • For valve and pump dispensing, Patented Mass Flow Control (MFC) uses weight-controlled dispensing and automatic calibration to deliver consistent fluid amounts throughout production.
  • For jet dispensing, Calibrated Process Jetting (CPJ) uses weight control to ensure precise volumetric repeatability and optimized line speed for jet-on-the-fly operations.
  • Jet-on-the-Fly (JOF) is a software feature that drives the DJ-9500 to dispense lines of dots without stopping. Dispense time is significantly reduced when compared to traditional needle dispensing.
  • Dynamic Dispense Control (DDC) offers precise and flexible control parameters through closed-loop servo technology. With encoders and feedback from the dispensing pump, the user can specify different acceleration and deceleration values for the valve or pump, allowing each dispense shot to be optimized for speed, accuracy, and yield.
  • There is a cleanroom model, the S-820-C, and a dual-lane model, S-822.

Other Features and Benefits Include

  • Fluidmove® for Windows® software for easy-to-use programming control
  • Patented Mass Flow Control automatically compensates for changes in fluid viscosity
  • Automatic Pattern Recognition System for accurate identification of global and local fiducials
  • Automated thermal management for reliable substrate heating and full temperature control of fluid delivery
  • Processes developed on the S-820 can be transferred to an inline Spectrum™ platform. Production can be expanded with minimal configuration downtime and seamless transition from engineering development to inline manufacturing.
