GPD Global, a manufacturer of precision fluid dispensing systems for high-volume 24/7, low-volume/high-mix and R&D production will debut its Positive Cavity Displacement (PCD) ‘H’ Series high-resolution pumps in Booth #1849 at the upcoming Assembly & Automation Technology Expo, scheduled to take place September 20-22, 2011 at McCormick Place North in Chicago, IL.
GPD’s PCD Dispensing provides next-generation volumetric dispensing and is compatible with materials used in electronics assembly such as epoxies, thermal greases, underfills, oils, silicones and UV encapsulants, as well as materials outside of the electronics industry. PCD Technology is designed for GPD Global platforms and may be used with other robots or tabletop operations with an easy-to-use tabletop controller.
Viscous fluids are delivered to the substrate via luer nozzles and performance excels when using GPD Global ‘S’ Taper tips. The metering technique is not affected by variations in temperature or reservoir pressure, thereby improving day-to-day and start-to-finish process results. GPD’s enhanced flow rate luer dispense tips offer higher flow rates than standard luer nozzles with a much lower pressure build-up.
GPD also will display the PCD Dispensing with a Syringe Mixing System that keeps fluids such as LED encapsulants with phosphor evenly mixed before they are dispensed.
