Abstract
Defectivity requirements are constantly put to new standards, even in older factories where new toolsets aren't a feasible alternative. To prolong the life of this equipment, Integrated Designs has created the digital dispense valve system. Tracks with older pump systems are plagued with repeatability and suckback issues that are key factors in eliminating or reducing defectivity. The digital dispense system not only increases the pump's capability to hold suckback across significant amounts of idle time regardless of viscosity, but also allows for lower dispense volumes due to more repeatable dispenses. Combining these factors results in a significant decrease in defectivity with only minor equipment additions, that previously would have required costly pump and track upgrades.
