Fluid Positioning &
Dispensing Applications
Camera Module
UV-cure adhesives
Adhesives
Epoxies
Other specialty fluids
As camera modules shrink in size, manufacturers need greater accuracy
when bonding lenses to barrels, barrels to camera modules, camera modules
to circuitry, and camera module holders to smart phone bodies.
The slightest overspray bonds components that should not be bonded,
creating more rework, which slows production and lowers yield. Nordson EFD
solutions feature built-in cutoff functionality, in addition to extreme deposit
accuracy, to eliminate overspray.
Other applications utilizing EFD dispensing solutions include, but are not
limited to:
• Die-bonding in packaging
• Frame bonding
• IR cut filter bonding
• Actuator and VCM bonding
Recommended Solutions
• PICO XP jet valve
• PICO jet valve (with needle adapter)
• 781Mini spray valve
• xQR41 Series needle valve
• EV Series automated dispensing system
• OptiSure AOI software
Benefits: Precise deposit accuracy eliminates overspray, increases
throughput, and reduces fluid waste.

Fluid Positioning &
Dispensing Applications
Microspeaker
UV-cure adhesives
Epoxies
Whether bonding microspeaker membranes or lids to assembly modules,
manufacturers need equipment to dispense deposits as small as 0.8 mg with
extreme accuracy.
Nordson EFD’s PICO jet dispensing solutions deliver continuous operation at
up to 1000 cycles per second (Hz) with shot sizes starting at 0.5 nanoliters.
Recommended Solutions
• PICO XP jet valve
• PICO jet valve (with needle adapter)
• 741MD-SS MicroDot needle valve
• xQR41 Series needle valve
• PRO4 Series automated dispensing system
• OptiSure AOI software and confocal laser
Benefits: Better process control and repeatable dispensing amounts (even
when changing pulse times).

General Assembly
Hydrophobic Coating
Hydrophobic coatings
Nordson EFD solutions enable the precise application of hydrophobic coatings
to select areas of mobile devices and wearables during final assembly. With
consistent, uniform micro spray patterns, these Low Volume Low Pressure
solutions prevent water ingress.
Liquid droplets fly off critical components such as speakers and microphones,
eliminating damage, which improves the reliability of the final product. This
enhances durability of the device components for long-lasting use during
their life term.
Recommended Solutions
• 787MS-SS MicroSpray valve
• 781Mini spray valve
• EV Series automated dispensing system
• 4-Axis R Series automated dispensing system
Benefits: Micro spray patterns between 1 mm (0.04") and 19.1 mm (0.75") in
diameter. Zero overspray and reduced waste and operating costs associated
with expensive protective fluids.
