Theory of Operation 1.4
The JDX Jet Valve is a high speed, non-contact dispenser that applies small shots of fluid
as individual dots or in rapid succession. Only 3 components come in contact with fluid:
the feed tube, diaphragm, and nozzle plate. The unique diaphragm design allows for fast
cycling of the jet, up to 300Hz for high speed line dispensing. The JDX is designed to
dispense coatings, underfill, encapsulant, SMT glue, grease, and more with very fine
control.
Description of Components 1.5
Refer to Section 2.1 for an overview image.
The bracket for 30cc syringe is one piece with jet body. Inserts are
available for smaller syringe sizes.
This component contains the pneumatic solenoid that controls the
on/off function of the jet.
Built into jet body, the fluid is warmed at the point of dispense.
A disposable tube with a female luer fitting. It supplies fluid from the
syringe to the nozzle plate.
Small component that fits into the heater and is held in position by the
nozzle plate. It comes in three materials for dispense material
compatibility.
The nozzle plate has the dispense port orifice in it and is connected to
the syringe with the feed tube. The nozzle plate is available in multiple
sizes and materials of dispense ports orifices.
