Fluid Positioning &
Dispensing Applications
Conformal Coatings
For precise, micro-spray applications of conformal coatings, the 787MS
spray valve uses Low Volume Low Pressure (LVLP) technology to apply a
fine, controlled mist onto microchip leads on the main printed circuit boards
of mobile and wearable devices. When paired with a spray valve controller,
which has a post-atomizing feature for clean spray cycle finish, the system
produces practically no over-spray or mist.
The valve system works best when fully integrated with a 3-axis E Series
automated dispensing system, which features an intuitive Teach Pendant
and custom EFD TeachMotion™ dispensing software for fast, easy setup
and programming.
Recommended Solutions
• 787MS-SS MicroSpray valve
• 781Mini spray valve
• E Series automated dispensing systems
Benefits: Ideal for micro-spray application of conformal coating, the 787MS-SS
provides narrow, consistent spray patterns as small as 1 mm (0.04") wide
without overspray.
Coupled with E Series tabletop automation, the dispensing system provides
market-leading positional repeatability at +/- 0.008 mm.

Thermal Compounds
Both the 725DA piston valve and 794 auger valve are ideal for thermal compound
applications because of their superior ability to dispense precise amounts of
high-viscosity sticky and stringy fluids. Together with a ValveMate™ valve controller,
these systems apply accurate, repeatable amounts of thermal compounds onto
heat sinks for central processing units (CPUs) and memory chips.
Each valve system works best when fully integrated with a 3-axis E Series
automated dispensing system, which features an intuitive Teach Pendant
and custom EFD TeachMotion dispensing software for fast, easy setup and
programming.
Recommended Solutions
• 725DA-SS piston valve
• 794 Series auger valve
• E Series automated dispensing systems
Benefits: Ideal for thermal compounds, the 725DA and 794 auger valves
provide exceptional deposit control without dripping or drooling between shots.
Coupled with E Series tabletop automation, the dispensing system provides
market-leading positional repeatability at +/- 0.008 mm.
