== About ==
'''NOTE: This equipment is part of [[Manual Assembly Station]].'''

Nordson EFD Ultimus I-II are high-precision benchtop fluid dispensing control for advanced applications of epoxy, silicones, sealants, glues, greases, cyanoacrylates, solder pastes, and other assembly fluids dispensed with syringe barrels. Featuring a digital display of all fluid dispenser settings and time adjustment as fine as 0.0001 seconds, Ultimus I-II dispensers bring exceptional control to medical device, electronics, and other critical dispensing processes.

== Application ==
A few of use cases pertaining to packaging:

* Die attach epoxy application

* Glob top and encapsulation

* Underfilling of EIC or optical path (e.g., hybridized laser)

* RTV for potting and anchoring

* TIM (thermal interface material)

* Optical path epoxy

===== Ultimus I vs II =====
Ultimus I:  Features '''0-100 psi''' (0-7 bar) constant-bleed air pressure regulation and provides greater control when dispensing '''any type of fluid'''.

Ultimus II:  features '''0-15 psi''' (0-1 bar) constant-bleed air pressure regulation and provides greater control when dispensing '''low-viscosity or thin fluids'''.
== System Overview ==
'''Dispenser'''

* The system manages deposit size through three primary variables: '''dispense time''', '''air pressure''', and '''vacuum pullback.'''
* It operates in three different modes: Timed, Steady and Teach.
* It can store job programs in memory for repeatable process.

'''Syringe Barrels'''

Materials to be dispenses should be in standard syringes connected to the dispenser via adapters based on syringe capacity (e.g., 3cc, 5cc, 10cc & 30cc).

'''Dispense Tips'''

For a proper dispense volume and pattern, correct dispense tip should be selected. Tips are categories by internal diameter (ID) gauge and are color coded. Optimum tip can be chosen through try and error but generally, thin and low viscosity material will require smaller ID (bigger gauge).
