Electroninks, the Austin-based manufacturer of metal organic decomposition (MOD) inks for additive manufacturing (AM) and semiconductor packaging, has introduced what the company claims is the “world’s first” commercially available copper MOD ink. According to Electroninks, one particularly sought-after application driving interest in copper inks “seed layer printing”, which involves the deposition of extremely thin layers of metal onto a substrate, making subsequent plating processes easier and more efficient.

 

Solar cells seem to be one of the areas in which seed layer printing shows the most promise. Electroninks claims that, compared to the currently dominant processes of electroless (e-less) copper plating and physical vapor deposition (PVD), AM with copper inks requires both far less water and energy.

 

In addition to enhancing the sustainability of the underlying production processes, that also contributes to customers’ ability to manufacture the relevant components with far less CAPEX than is required with conventional methods. Along with seed layer printing, Electroninks is already working with customers to explore the potential for its copper MOD inks in areas like advanced semiconductor packaging.

 

In a press release Electroninks CEO and co-founder Brett Walker, said, “These copper inks bolster Electroninks’ strong and diverse MOD ink product portfolio and deliver best-in-class ESG and cost savings to customers.”

Jim Haley, the VP of Marketing for the International Microelectronics and Assembly Packaging Society (IMAPS) Executive Council, said, “MOD inks, which have been on the market from Electroninks for a few years now, provide unique properties that are well suited for today’s semiconductor wafer and module-based packages requiring high-performance thermal and power management. By introducing a copper-based MOD product, markets and customers are generally more supportive, as copper is a standard in electronic design for many use-cases. While silver, gold, and other MOD inks will continue to serve this market, we welcome copper MOD inks to address key needs in advanced packaging.”

 

In addition to helping the reshoring effort in the US for the industries where it matters most — semiconductor packaging and green energy — Electroninks has made significant inroads into the Asian Pacific market in recent years, namely in Japan and Taiwan. Of course, this bolsters the US’s  reshoring effort as well, as the American domestic market can’t advance forward without heightened cross-collaboration between the US and its leading trade partners outside the Chinese mainland.

 

As far behind as the US may still be in achieving its goals to build the domestic green energy and semiconductor manufacturing bases, the bright side to this is that the nation can, to a significant extent, start from scratch in building its new industrial ecosystem. Whereas other nations have already committed themselves to doing things the old way, the US can focus on accentuating its advantages in truly forward-thinking areas like conductive inks.

New copper ink displaces electroless copper plating and other industry-standard manufacturing processes with significantly faster production speed, lower ownership cost, and greater sustainability levels

 

AUSTIN, TX & SEMICON TAIWAN – September 3, 2024 – Electroninks, the leader in metal organic decomposition (MOD) inks for additive manufacturing and advanced semiconductor packaging, today announced the launch of the company’s advanced conductive copper ink line.

Electroninks will be showcasing the new copper ink line at booth Q5152 in Hall 2 of SEMICON Taiwan September 4-6, 2024.

 

A high-demand application for the new copper ink is seed layer printing for fine-line metallization and RDL formation in combination with the company’s proprietary iSAP™ process. For this application, Electroninks copper ink effectively displaces industry use of electroless (e-less) copper plating and physical vapor deposition (PVD) tie layers while achieving a significant increase in manufacturing throughput and a vast reduction in ESG footprint. Compared to legacy methods (PVD and e-less), ink-based additive printing uses a fraction of the water and energy, factory footprint and CAPEX, thus providing customers with the lowest total cost of ownership and highest ROI on the market.

 

The copper inks are deposited by spray coating, screen printing, inkjet, spin-on, and other conventional printing methods. Beyond the seed layer application, Electroninks is working with customers on a multitude of applications, including advanced packaging, serving a diversity of markets. “These copper inks bolster Electroninks’ strong and diverse MOD ink product portfolio and deliver best-in-class ESG and cost savings to customers.” stated Brett Walker, CEO and co-founder of Electroninks.

 

“MOD inks, which have been on the market from Electroninks for a few years now, provide unique properties that are well suited for today’s semiconductor wafer and module-based packages requiring high performance thermal and power management.” stated Jim Haley, Vice President of Marketing, IMAPS Executive Council. “By introducing a copper-based MOD product, markets and customers are generally more supportive, as copper is a standard in electronic design for many use-cases. While silver, gold, and other MOD inks will continue to serve this market, we welcome copper MOD inks to address key needs in advanced packaging.”

 

Electroninks is offering a range of copper ink grades to address customer demand for adhesion to various substrates, including glass, silicon, and EMC. These inks are compatible with multiple printing techniques and can be cured at low temperatures for short times – as low as 140C in 5 minutes under nitrogen or ambient conditions.

Broader selection of metals fuels innovation in product development and provides greater flexibility in manufacturing

AUSTIN, TEXAS — Jan 12, 2022– Electroninks, the leader in particle-free conductive metal inks and advanced materials, today announced the addition of gold (Au) and platinum (Pt) particle-free conductive inks to its catalog of products. The addition of gold and platinum inks gives makers of consumer electronics, medical devices, sensors and semiconductors the ability to make lighter, less expensive, and more environmentally friendly products.

​​The demand for powerful microelectronics packed into consumer and industrial products of different shapes and sizes has never been greater. From foldable displays in new 5G phones to medical sensors in athletic wear to new materials and architecture in semiconductor packaging, powerful tiny circuitry is making it possible, and Electroninks’ broader line of conductive inks is enabling greater innovation in this field.

Electroninks has already established a superior particle-free ink in the market with its conductive silver ink. The new gold and platinum metal inks consist of metal-organic precursors that decompose cleanly at lower temperatures than nanoparticle inks and can be UV-cured. The inks are unique to the market, providing deep savings on material use (and waste) and costs for customers by enabling similar electrical and reliability properties of vacuum or plated films of gold and platinum.

Opening additional doors in product manufacturing, the new inks are catalytically active (may serve as a seed layer) and have a high corrosion resistance — ideal for protective circuits, gas, thermal and biological sensors. Unlike traditional gold and platinum inks that are based on metal nanoparticles dispersed with organics/polymers which degrades performance, Electroninks’ particle-free inks enable reliable printing and manufacturing in non-typical and even space-like environments for its aerospace and defense customers.

Commitment to the Customer
Electroninks first developed silver inks based on the philosophy that pure metallic films are the best way to increase performance and reliability while reducing overall cost of manufacturing and ownership. Aligning with its mission to fundamentally change the way its customers develop new hardware technologies and improve manufacturing processes, Electroninks developed gold and platinum inks to fill the need of a wide range of applications in electronics, including forming contacts in microelectronic devices, high temperature, electrochemical and catalytic applications. The gold and platinum inks provide high performance and reliability at high temperatures, making them ideal for use in aerospace and biomedical devices.

“As electronic materials and supply chains become more critical due to their usage in nearly all products that impact our lives, the demand for innovation and products making it all possible has hit a tipping point, as we have seen in the past year.
