Inkjet printing of electronic components and circuits.
Ink jet printing electronic components using nano-ink gives a possibility to create flexible devices, equipment and devices, including flexible printed circuit boards, with enhanced performance, increased reliability and environmental safety. Such printing ink is produced on almost any surface (including flexible) with an accuracy of a few microns, using both existing printing devices, and conventional ballpoint pens.
Inkjet printing of electronic components is a promising technology for creating various electronic circuits, RFID (Radio Frequency IDentification) tags, micro-supercapacitors , etc. electronic components. It is based on the use of nano-ink metal (gold, silver, platinum, etc.), semiconductor nanoparticles, carbon nanostructures (graphene, carbon nanotubes), characterized by high conductivity, stability, low temperature sintering. Such printing ink is produced on almost any surface (including flexible) with an accuracy of a few microns, and the sizes of the printable items are 20×20×3 µm and above.
The combined use of nano-ink (with the properties of conductors, semiconductors and insulators) and is already available on the market modern printing platforms (inkjet printing, engraving, etc.) can significantly reduce the cost of electronic products, increase the efficiency of their production, to create flexible devices with improved performance, increased reliability and environmental safety.
Inkjet printing is carried out, for example, already available on the market branded printer Dimatix DMP-2831, is equipped with a cartridge with 16 nozzles, outstanding output drop volume of 10 PL, and using ordinary ballpoint pens. In the latter case, the nano-ink is put into the rod of a ballpoint pen, which is used for application of conductive connecting elements on different substrates (glossy paper, glass , etc.).
Inkjet technology differs from other, widely used now in the manufacture of electronic devices (photolithography etc.), low cost and the ability to print on almost any substrate (plastic, paper, film, etc.), and the substrate does not undergo any significant changes during the printing process. Thus, with the help of this technology it is possible to create flexible, transparent electronic devices at relatively low cost.
The end products of inkjet technology are batteries, capacitors, micro-supercapacitors, thin film transistors, memory cells, OLED and LCD displays, sensors, RFID tags and antennae, photodetectors, capacitors, solar panels, connecting elements in the chips, holograms, minerals, chips, etc.
In ink-jet printing technology from the point of view of prospect interest in the use of the inks of graphene and carbon nanotubes. This is due to the much higher conductivity, carrier mobility than silicon, making them promising for the fabrication of transistors with high speed switching.
