GPD Global’s PCD Technology Is Proven Compatible with Silver-filled Electrical and Thermal Epoxies

Dec 07, 2010

GPD Global, a manufacturer of precision fluid dispensing systems for high-volume 24/7, low-volume/high-mix and R&D production, announces that its Positive Cavity Displacement (PCD) technology is proven with silver-filled electrically and thermally conductive adhesives.

The volumetric capability of PCD Technology improves repeatability from unit-to-unit resulting in uniform bond lines without excessive squish-out after device placement. The unique progressive cavity dispense technology can meter fluids with ±1 percent repeatability. The line width is dependent on the fluid and nozzle configuration and current testing has easily yielded line widths of 0.025 mm (0.010").

During the pot life of the fluid, the system does not need to be adjusted, allowing for an adjustment free process. Coupled with a GPD Global Max Series platform, complex patterns can be created and dispensed with exceptional repeatability and positional accuracy.

The PCD Series also can be integrated into robots or used on the tabletop with the easy-to-use pump controller. PCD technology has proven to be faster and more repeatable than conventional auger and time pressure systems. As an additional benefit, the system features the ability to run over the full pot life of the fluid without adjustment to the pump parameters. With these key advantages, PCD Technology is an easy way to improve capabilities and throughput, as well as the preferred dispensing solution for new system acquisition.


GPD Global is an equipment manufacturer of high-quality, precision, automated fluid dispensing and component-prep systems. The company is an international, state-of-the-art equipment supplier for the PCB assembly and semiconductor industries. It designs and manufactures a variety of automatic fluid dispense systems, as well as manufactures an SMT Cover Tape Peel Tester and Component Prep equipment for Thru-Hole applications. GPD Global is committed to offering premium service to its customers and has sales and customer support affiliates located throughout the world, including North America, South America, Europe, the Middle East and Asia-Pacific.
