Fluid Positioning &
Dispensing Applications

UV resins and adhesives
Optically clear adhesives (OCAs)
Conductive pastes
Other specialty fluids
Nordson EFD solutions provide greater precision in multiple display assembly
applications.
Whether bonding cover glass to LCDs and OLEDs or edge sealing and end
sealing of LCDs and OLEDs, Nordson EFD solutions deliver consistent,
repeatable deposits at high speeds.
Mobile device and wearables manufacturers prefer EFD solutions for gap-fill
applications, in addition to more specialized applications such as optical
bonding and seal bonding dispensing anisotropic conductive fluids in very
narrow spaces.
ACP bonding seal or electrode seal applications involve dispensing between
the display module and driver I/C. As the gap between modules and driver
I/Cs gets narrower and glass thickness gets thinner, non-contact dispensing
is preferred to drive higher productivity.

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.

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).
