Printed electronics technology is going to the nano level, are you laid out in advance?

The future of nanotechnology for printed electronics is becoming more and more important, not only in Europe but in a revolution in science and technology in every corner of the world. 

If the printed electronics industry wants to further expand the market, it must learn to use nanoscale particles and materials in PCB inks. Printing electronics will benefit from this growing market because of the lower cost of printing electronics applications and the ability to use nanoscale inks and coatings on a variety of substrates. 

Printed electronics

At present, many materials can be used to produce nano-components such as carbon, silver, iron, titanium dioxide, aluminum oxide, antimony oxide, zinc oxide, silicon dioxide, silicon dioxide, and nano-clay, although they are not currently fully used. In ink and coating formulations, but the future development potential cannot be ignored.

In addition, nanotechnology needs to meet many difficult challenges in order to be widely used in printed electronics and other fields. The most difficult part is to alleviate people's health and safety concerns, especially in Europe where policies and regulations are relatively strict. 

Steve Hankin, the senior consultant at the British Institute of Labor Health, said: 'The safety information on nanomaterials in the market is not complete, and there are huge gaps in knowledge in toxicology, physical properties, and exposure data. People face great difficulties in risk assessment and risk management of nanomaterials. As a result, many companies in Europe require their suppliers to specify the nano-components in their products, especially packaging products.

In addition to safety, another headache is the increase in the cost of nanomaterial research and development. This requires not only a high level of R&D staff but also expensive equipment. In order to further the pace of technological innovation, small businesses need to invest a lot of money.

Strict health and safety requirements and increasing research and development costs make nanotechnology a luxury that far exceeds the limits of some ink manufacturers. Even some large companies in the ink market can't afford the cost of setting up an internal R&D team.

In addition to companies specializing in nanotechnology, some universities and research institutions in Europe are also very interested in nanotechnology and penetrate into the ink market by making inks or providing nano-ingredients for ink products. For many years, ink manufacturers and milling methods have been used to produce nano pigment particles to improve the color quality and performance of ink formulations.

The use of nanotechnology in conventional coatings provides scratch-resistant properties to substrates. Inks containing nanoparticles can be used in most printing processes, especially in the production of printed electronics. Currently, nanomaterials can be printed on a variety of substrates for the production of RFID tags, fluorescent displays, plastic cells, sensors, and solar cells.

The use of nanotechnology in conventional coatings

In the field of printing, inkjet inks are the most used in nanotechnology because they require the addition of small particles to the formulation, especially for dyes and pigmented inks. The development of inkjet technology complements nanomaterials. With the maturity of inkjet printing technology, nanomaterials have also made exciting progress. For example, nano-nano materials used in inkjet printing can also be used in the production of photochromic or electrochromic inks, antibacterial agents, flame retardants, conductive graphite and metals, magnetic materials, enzymes, and other biological materials.

Nanomaterials in traditional and inkjet inks are used in security, brand protection, and anti-counterfeiting, and this is one of the largest markets for nanotechnology in the printing industry.

Under current market conditions, we'll pay close attention to regulators in Europe and other countries, and understand the overall level of development of this technology to find the best direction for the PCB manufacturing and assembly.
