  • EFD Announces New Auger Valve System
    By combining screw-feed principles with precise time and dispensing controls, the auger valve system provides accurate, repeatable deposits of thick, particle filled fluids.

  • Design and characterization of a precision fluid dispensing valve
    Furthermore, the dispensing system should be flexible enough to accommodate materials of different viscosity ranges while being easily maintainable for ser- viceability to minimize down time. Over the years, many systems have been developed ranging from fixed tooling such as pin transfer and screen printing to more flexible systems such as time pressure, positive displacement and auger screw valves [1, 2, 3].
  • Auger Valve Dispensing
    Auger valves are intended for use with constant pressure when dispensing solder paste. The system relies on the inherent resistance to flow provided by the auger screw and the dispense …
  • Dispensing flip chip underfill process problems and solutions
    By using auger screw technology coupled with a vertical actuator, it was possible to close the valve completely when not dispensing and therefore eliminate any dripping or contamination due to the higher feed pressures and large volume auger screws. … auger to sit back into the needle feed reservoir when not is use, sealing the entire system .
  • Dispensing flip chip underfill process problems and solutions
    This vertical actuator lifts the auger screw to allow flow when rotating and then allows the auger to sit back into the needle feed reservoir when not is use, thus sealing the entire system . This type of advanced rotary valve technologyhas proven to give volume repeatability of <+I- 2% with dispensed volumes in the region of 10 to 50 milligrams.
  • Model-based robust design for time–pressure fluid dispensing using surrogate modeling
    The fluid dispensing system [1], which discharges the desired amount of fluid to a workpiece, is widely used in various applications where fluid manipulation is needed, such as chip packaging and circuit assemblies, chemical/ biological analysis systems, etc. In all these dispensing applications, three kinds of dispensing methods are mainly employed, namely, time–pressure dispensing, auger pump dispensing, and piston valve dispensing.
  • A Simple Model-Based Approach for Fluid Dispensing Analysis and Control
    AUTOMATIC fluid dispensing is one of the key technolo- gies in advanced electronic manufacture, and is widely used in chip packaging and circuit assembling, chemical anal- ysis systems , etc. [1]–[3]. There are many different dispensing approaches reported in the literature [4]– [7], including time– pressure dispensing, auger pump dispensing, piston valve dis- pensing, and jetting dispensing, which are four most popular methods used in electronics packaging [8]–[10].
  • Auger Valve Dispensing
    But, as with many other flexible systems , there exists room for use and abuse of the features … It is worth noting here, in the introduction that while highly accurate and rapid in response, auger valves do not dispense material quickly.
