OUR COPPER INK
Copper is a key material in the electrical and electronics industry, it is highly electrically and thermally conductive, as well as low cost. Printing of copper has been this industry’s dream for many years. However, physical barriers prevent effective printing of copper mainly due to oxidation considerations.
To date, most platforms printing electronics use silver-inks which are highly conductive and do not oxidize but are expensive and pose significant challenges in performance. This is why copper-ink is so important. This is why PrintCB’s copper ink is so disruptive.
High electrical conductivity <20 mΩ/sq./mil
Tune-able viscosity 5,000-100,000 cP
Ideal for Screen Printing or micro-Dispensing
Hot-air/IR curing at 145°C for 1 minute only
Minimum film thickness (screen, 1 pass) ~10 microns
Good adhesion to many substrates such as PET, polyimide, silicon and others
Solder-able to either leaded or lead-free soldering materials
Good flexibility at low thicknesses
PrintCB’s copper ink processing requires zero changes to capital equipment (i.e. inert gasses or laser sintering) and can cured in air using standard conveyor or box ovens, while maintaining high conductivity.
In order to support the Smart-Manufacturing AKA Industry 4.0 vision, digital printing technology for copper ink has to be in place. PrintCB’s copper ink are highly compatible to Screen printing and micro-dispensing, both well established printing technologies. Our ink is not brand specific and can be applied with the various dispensing systems in the market.
Possible applications for this new digital solution may include: printing of connections, sensors, circuitry repairs, antennas, heat-sinks, IC packaging and more.
