ELECTRONICS APPLICATION

Conductive Ink

Ultrasonic atomization for depositing conductive inks containing silver and copper nanoparticles, carbon nanotubes, and graphene for printed circuits, flexible electronics, OLED displays, and transparent conductive films.

The Challenge

Printed electronics require uniform deposition of conductive inks containing nanoparticle suspensions. Conventional spray methods cause sedimentation, clogging, and "coffee-ring" effects that produce inconsistent resistance and capacitance across printed areas. Aerosol and inkjet methods struggle to balance deposition rate with resolution for production-scale applications.

Our Solution

MicroSpray ultrasonic nozzles produce an extremely fine mist of ink droplets for even coating coverage without coffee-ring effects or thickness variation. The vibrating nozzle tip naturally prevents sedimentation and clogging, allowing use of high nanoparticle-loading inks that would foul conventional spray heads. The low-velocity mist can be focused or stenciled to print fine circuit traces with excellent edge definition.

Why Ultrasonic Spray?

✓Uniform coating eliminates coffee-ring effects and thickness variation
✓Vibrating nozzle tip prevents sedimentation of high nanoparticle-loading inks
✓Transfer efficiency above 90% reduces waste of precious metal inks
✓Highly reproducible resistivities and layer thicknesses device-to-device
✓Fine circuit traces with excellent edge definition
✓Compatible with silver, copper, ITO, carbon nanotube, and graphene inks
✓Scalable from PCB prototyping to roll-to-roll production lines
✓Non-contact spray safe for delicate polymer and paper substrates
✓Low-temperature sintering compatibility enables use with heat-sensitive flexible plastics
✓Uniform nanostructured coatings improve sheet resistance and reduce failure points in OLED displays, solar cells, and touchscreens
