As medical devices, electronics, cell phones and many other products continue to put more and more features into smaller and smaller packages, manufacturers need new ways to apply adhesives, coatings and other assembly fluids in smaller, more precise amounts than ever before. Thus EFD, a subsidiary of Nordson Corporation, introduces the new PicoDot Jet Dispensing Systems. The new jet dispensing systems bring significant new capabilities to EFD’s extensive line of precision fluid dispensing systems. Because the PicoDot systems do not contact the substrate, they will enable manufacturers to deposit controlled amounts of fluid on hard-to-access areas, uneven surfaces, or in applications where a conventional dispensing needle cannot be used — at speeds up to 150 dots per second. Multiple PicoDot system configurations make it possible to dispense a wide variety of low (50–1,000mPas), medium (50– 200,000mPas), and high (1,000– 500,000mPas) viscosity fluids in a wide range of manufacturing applications. Capabilities of the PicoDot Jet Dispensing System include:· Non-contact jetting, including three-dimensional substrates;· Non-contact dispensing of lines;· Covering areas by jet dispensing of droplet arrays with shot size starting at 0.002 µl (2 nl) to flow rates up to 300 g/min (10 oz/min).· Optional precision needle adapter allows contact dispensing of dots and beads with excellent consistency and highest positioning precision. An integrated heater is available for precise viscosity control.
