Miniature Precision Dispensing Valve for Micro-Assembly and
Electronics with Ultra-Fine Flow Control
Product Description:
When every microliter counts, our 20mm metered valve provides the
miniature precision required for the most delicate assembly tasks.
This valve is a masterpiece of miniaturization, engineered to
dispense ultra-small, consistent volumes of inks, conformal
coatings, fluxes, and adhesives used in micro-electronics, medical
device manufacturing, and watchmaking. The ultra-fine flow control
is achieved through a meticulously calibrated mechanism and a
jeweled orifice, enabling sub-microliter dosing accuracy. Despite
its miniature internal features, the valve maintains a robust 20mm
outer thread for easy integration into automated platforms and
robotic arms. Its compact design minimizes dead volume, reducing
fluid waste of expensive specialty chemicals. This valve is the
critical link in your process that ensures the reliable placement
of minute amounts of material, directly impacting the performance,
reliability, and miniaturization of your final product.
Bullet Points:
Enables miniature precision dispensing for volumes as low as 0.1
microliters.
Features an ultra-fine flow control mechanism with a jeweled
orifice for unmatched accuracy.
Compact design with minimal dead volume to conserve expensive
fluids.
Ideal for applying adhesives, coatings, and lubricants in
micro-electronics assembly.
Standard 20mm thread allows for easy mounting on robotic
dispensers.
Specific Application Scenario
On a circuit board assembly line, a robotic arm uses this valve to
place microscopic dots of conductive epoxy onto sensor pads before
attaching a chip. The valve's ultra-fine control prevents bleeding
or short circuits.
Factory Production Floor
Production occurs in a temperature and humidity-controlled
cleanroom. The assembly of the ultra-fine flow control mechanism
requires microscopic vision systems and is performed by highly
trained technicians to ensure flawless performance.
Packing and Transportation
Each valve is packaged in a class-100 cleanroom bag within a rigid
plastic clamshell to protect it from shock and contamination. These
are shipped in anti-static boxes marked "ESD Sensitive" and
"Fragile Component."
FAQ
What is the smallest volume this miniature precision valve can
dispense?
The standard model can reliably dispense down to 0.1 µL.
Specialized versions can achieve even smaller doses.
How is the ultra-fine flow control calibrated?
Each valve is individually calibrated using a gravimetric method
with a high-precision scale, and a calibration certificate is
provided.
What types of fluids can the jeweled orifice handle?
The jewel orifice is extremely hard and wear-resistant, suitable
for most fluids. However, it can be fractured by abrasive slurries
with large, hard particles.
How do I prevent the tiny orifice from clogging?
Using filtered fluids is essential. We recommend in-line filters
right before the valve inlet. The valve can also be purged with
solvent periodically.
Can this valve be used for medical device manufacturing?
Yes, we offer a certified version with full material traceability
and biocompatible seals suitable for medical and life sciences
applications.
