Liquid Deposition
Inkjet technologies as utilized in the traditional digital
printing industry are perfectly suited to controllably dispense
small and precise amounts of "liquid" to precise locations. The
"liquid" materials can encompass low to high viscosity fluids,
colloidal suspensions, frits, metallic suspensions, and almost any
other material that can be dispersed in a liquid carrier material.
The carrier material can be aqueous or non-aqueous based solvent
material.
All digital inkjet technologies are suitable for liquid and fluid
deposition, depending upon the specific application and
requirements. The available inkjet technologies include:
- Continuous inkjet
- Drop on Demand inkjet
- Thermal inkjet
- Piezo inkjet
Torrey Pines Research recognizes that successful integration of
inkjet technology requires the careful integration of the three
critical elements of inkjet printing:
- The fluid or liquid material
- Typically defined by the
application
- The substrate upon which the liquid will be deposited
- Typically defined by the application
- The inkjet dispenser or head, including driver electronics
TPR understands the critical nature of these
interactions and is expertly positioned to find and/or develop the
right match for your application.
Torrey Pines Research is uniquely positioned as an independent
integrator of inkjet technology for your specific application
because TPR is technology and supplier �neutral�. As such, TPR is
best able to select the most appropriate inkjet technology & head
supplier to integrate with your application requirements for the
fluid and substrate.
Typical application requirements for liquid deposition, metering,
dosing, dispensing, masking, and coating include the following:
- Liquid materials
- From solutions to colloidal suspensions
- Usually
expensive ($/lb)
- Small area coverage
- Relatively low volumes of
material
- Small & precise metering
- Requiring drop sizes from ~ 3 to
100+ Pico liters
- High resolution
- Precision drop location
- Sometimes
within +/- 1 micron
- Non-contact process
- Typically for testing and/or
manufacturing
