Large-format fluid dispenser

16 July 2014 Manufacturing / Production Technology, Hardware & Services

New from Nordson ASYMTEK is the Quantum Q-6800 large-format dispensing system for SMT, PCB packaging and microelectronics assembly applications. Its dispense area of 423 x 458 mm handles a wide range of substrate sizes and is large enough so the dispense area is not compromised even with dual valve configurations, enabling flexibility in the dispensing process.

The patent-pending Continuous Path software feature optimises dispense-head motion to save time and increase units per hour for jetted line applications, while Nordson ASYMTEK’s advanced, patented process controls ensure accurate and reliable dispensing results that meet the technology and manufacturing needs of demanding SMT and electronics assembly operations.

Optional dual-action or dual-simultaneous valve configurations aid high-throughput applications and can reduce dispensing time by up to 50%.

The Q-6800 dispenses precise volumes of fluid in dots, lines and patterns, and incorporates a laser height sensor for real-time, fast, non-contact dispense height measurement, as well as a digital vision system with high-brightness RGB LEDs for enhanced image contrast and detection.

Patented Calibrated Process Jetting (CPJ) software automatically compensates for changes in fluid viscosity, ensuring precise volumetric repeatability and optimised line speed for closed-loop fluid dispensing reliability, while mass flow calibration technology uses weight-controlled dispensing and automatic calibration to continuously deliver consistent fluid amounts, especially for valve and pump dispensing.

The Quantum platform supports most Nordson ASYMTEK jets, pumps and valves, including the DispenseJet DJ-9500 and NexJet NJ-7 jet valves.
