Novacentrix: Metalon Conductive Inks

Overview

Metalon conductive inks capitalize on advanced materials and formulation to provide conductivity options for additive manufacturing of printed electronics like photovoltaic devices, RFID, smart cards/labels, displays, and advanced packaging.

Utilizing nanoparticles and flakes, Metalon inks are formulated for specific applications and print methods. Variants already developed include silver inks suitable for application by inkjet, flexographic printing, and gravure. True copper inks are also available for screen, flexographic, or gravure application. In conjunction with the PulseForge® technology also from NovaCentrix, these inks can be applied to substrates such as plastic films, and even paper. The PulseForge tools use brief, extremely high-powered pulses of light from special custom lamps to sinter inorganic inks and films, including Metalon inks, at room temperature. The combination of Metalon and PulseForge allows conductivity requirements to be met using thin flexible substrates, and most substrates remain unaffected because of the very short pulse duration.

Key Features

  • Metalon inks are designed specifically for use with low-temperature substrates including paper, PET, and other plastics including polyethylene film.
  • Metalon copper inks have been available from NovaCentrix for over 4 years, and can be printed and cured in an air environment without inert or reducing atmospheres.
  • Metalon inks can be cured within microseconds using PulseForge tools and can be used with existing print lines to attain new levels of performance.
  • Metalon silver and copper inks and PulseForge tools can allow existing printing equipment and infrastructure to produce new electronics products, opening new markets and driving higher value.

Performance

Sheet resistances as low as 4 milliohms per square and resistivities as low as 3X bulk have been attained with silver ink. Sheet resistances below 100 milliohms per square and resistivities as low as 3X bulk have been attained with copper ink. Performance varies depending on print method and substrate.

Current Metalon inks

JS-015: Inkjet silver in water
Launched in January 2009, JS-015 is an inkjettable, aqueous, nano-silver ink formulated for a broader variety of porous and non-porous substrates, such as plastic films, papers, glass, quartz, and even silicon. Additional curing with thermal or PulseForge equipment will further increase conductivity. This ink is suitable for piezo-style inkjet heads.

HPS: Screen-print silver inks in water
Designed to produce conductive traces on substrates such as PET, glass, polyimide, and silicon.

FS-066 /FS-067: Spray deposition in solvent
A stretchable, nano-silver, solvent based ink that retains conductivity with up to 100% elongation. This ink was formulated for polyethylene film, and is also compatible with other plastic substrates. FS-066 is formulated for spray deposition, and FS-067 is for gravure deposition.

New inks under development
Metalon inks are optimized for specific application requirements, including print method, substrate, and target performance. NovaCentrix is actively developing new ink products to meet the needs of our customers. Contact us for any of the above inks, or for information on inks for customized applications.

Novacentrix:: Printed Electronics :: Photonic Curing :: Photonic Sintering :: Photosintering :: Conductive Inks :: Flash Annealing :: Sintering Nanopa

NovaCentrix’s patented pulsed plasma process produces unagglomerated nanopowders with unsurpassed size control in the range of about 10 nm to 100 nm in diameter. The particles are synthesized using a repetitive, high power, pulsed electrical arc discharge between two feedstock metal rods. After quenching, the nanoparticles are removed from the gas stream, the electrodes are indexed in, and the process is repeated.
