At productronica 2013, Global manufacturer and supplier of conformal coating and precision dispensing systems, PVA (Precision Valve  Automation, Inc.) will introduce its new jetting valve, as well as show the flexibility of its capabilities to manufacture custom solutions beyond conformal coating, at productronica 2013 on Stand A2/354.

Making its European debut at productronica, held in Munich, is PVAs new JDX Jet Dispense Valve featured on a PVA6000 Coating / Dispensing System. The JDX is an extremely fast, non-contact jet dispenser that precisely dispenses viscosities up to 400,000 cps, including difficult to work with fluids, which can be dispensed in volumes as small as 10 nanoliters (nl). PVAs jetting valve offers exceptional repeatability, moves swiftly and easily into awkward, hard to reach areas and dispenses a wide range of fluids including underfill, coatings, adhesives, epoxies and lubricants. The JDX integrates onto all PVAs coating/dispensing platforms and is backed by PVAs application expertise.

Showing the manufacturers diversity is the PVA710 Optical Bonding System, fitted with aVPX-450 Volumetric Pump, which provides a complete optical bonding solution including dam and seal dispensing and curing, fill dispensing and cover placement. The system is used to dispense optical bonding adhesives and assemble optical devices in atmosphere without bubbles. It is ideal for use with optically clear acrylics or silicones. Applications include bonding touch screen to LCD, cover glass to LCD, etc.

Also demonstrating PVAs range of capabilities at productronica is a PVA650 Selective Coating / Dispensing System in a custom configuration showing dispensing and pick and place assembly. The application simulates glass or enclosure bonding for hand held electronics in an inline configuration. Dispensing is performed with a VPX-2K Volumetric Pump, used for dispensing small dots and fine lines of 2 part adhesives in any ratio from 1:1 up to 100:1. Line patterns can be applied under 0.5mm wide and dots can be dispensed as small as 1mg or less. The pick and place function is handled by custom vacuum tooling on the robot head. Other features include integrated nozzle cleaning, software controlled pressure monitoring laser height sensing, and vision tools for alignment and inspection.

Demonstrating PVAs core capability of accurate and repeatable conformal coating is a PVA650 equipped with the FC100-CF Film Coating Valve and FCM100 Micro Dispensing Valve. The PVA650 on demo at the show is equipped with the optional four-axis option with valve tilt and rotate. The system is closed-loop, featuring optical encoder feedback on all axes and accuracy of 25 microns. In addition, the system can incorporate a variety of valves for multiple dispensing applications in one cell. The PVA650 is extremely flexible and is ideal for not only conformal coating, but also dispensing applications such as potting, bead and meter-mix applications.

PVA will have an International Team on Stand A2/354 to answer your questions regarding the demo equipment and applications, as well as any coating, general dispensing, and custom automation questions.
