The Latest from Copprint

Copprint powered products.
Great picture from a Chinese customer. Four products made with Copprint’s conductive copper paste on glass and aluminum.
Instead of a polluting etching process, a sustainable lower-cost printing process is implemented.

Additive Manufacturing of Electronics requires good soldering and is enabled with Copprint’s conductive copper inks, as demonstrated by the formation of an IMC layer (Inter Metallic Compound). This layer is formed during reflow between the solder alloy and printed conductive copper paste and is the index of good soldering (see explanation here ).

Full process details:

1. Print copper traces on FR4 substrate with Copprint copper pastes.
2. Soldering process – can be done even one week after sintering.
   1. Print off-the-shelf solder paste. (The most recommended paste is Henkel Loctite LF-318).
   2. Component placement.
   3. Standard reflow process.

Die shear tests after the process indicated >3Kgf for 1206 SMD resistor soldered on Copprint’s LF360 with SAC305 Loctite LF-318.

We are excited to announce two new top-performing nano-copper paste:

LF-371 for thick printing on multiple substrates such as FR4, Glass, Alumina, Aluminum, Ceramics.

LF-390 for printing on Polyimide (PI).

Best conductivity among conductive pastes and best price/performance.

Take an FR4 board, drill holes (2 minutes), print Copprint’s LF370 paste on both sides (2 minutes), sinter (3 seconds) and you are done. Tens of circuits in one hour.
The cheapest and fastest way to fabricate short and medium series of simple circuit boards.

– Highest conductivity among all conductive pastes.
– Sheet resistance ~2.2mΩ/□/mil
– Cheaper than etching.
– 5-10x cheaper than silver inks
– Environmental friendly process.
– Excellent adhesion and durability
– Solderable

Our amazing scale-up and production manager, Avraham (Avi) Kenigsberg, tested just this. Avi placed in his home composter two types of RFID antennas: standard etched aluminum RFID antennas, and our copper on paper RFID antennas. Can you guess what happened after 30 days?

We presented these results in our talk on “Compostable RFID antennas” on August 6. #PrintedElectronics Insights Series: Special Topic – #SmartPackaging. Klaus Hecker, Jan Krausmann from OE-A, Carolina Gioscio from #Evonik, Wolfgang Mildner from #MSWtech together with Copprint talked about the latest developments & applications of Printed Electronics that will drive forward the transformation of the #packaging industry.

Who cares about the tag?
During the pandemic shutdown, our talented Senior Researcher, Yitzchak (Isaac) Rosen, wrote the screenplay, starred, and edited this short movie about RFID tags’ environmental impact.

Do you also care about RFID tags’ environmental impact?

Copprint is leveraging our unique nano and submicron copper scalable production, to produce an anti-viral additive for multiple products.

In the global fight against Covid19, copper is proven to be effective in killing viruses. Nano Copper has a high surface area relative to volume and high effectiveness per weight, delivering the most effective protection against viruses and bacteria. Even bacteria spores, which are known to be highly resilient, are destroyed by a small amount of Nano Copper additive 1000X more than standard copper.

Copprint’s nano and sub-micron copper are dispersed in various solvents or water, enabling fast integration, due to the high dispersibility, into many processes and products. By adding just one percent of Copprint Nano Copper to standard paint, powerful anti-microbial and anti-viral performance is observed.  Copprint’s Nano Copper can be used as an additive for injection molding, paints, textile impregnation processes, 3D printing materials, ink jetting and more.

Copprint Nano-Copper coatings provide the best price/performance and are easier to apply than any other copper particles.

Copprint is one of 35 companies selected from 750 applicants by the Israel Innovation Authority, granted special funds to develop solutions that contribute to the global fight against Covid-19.
