Description: Aerosol Copper Ink Jet Printing - Inks, Ink Jet Printing - Silk Screen Printing

All along, the copper is always Printed circuit board Industry preferred conductive metal

. However, now, silver has become a large number of current products mainly used in printing Metal Ink , And all other printed electronics applications, the primary metal ink. The current products include ultra-high frequency (UHF) radio RFID ( RFID ) Antennas, membrane keyboards, battery testers and flexible displays.

Unfortunately, the next few years, the cost of silver will enter the exponential growth of demand for low cost and high quality metal ink came into being.

Principle, copper has excellent electrical conductivity, therefore, can more than most of the applications in use instead of silver; However, metal printing ink must overcome many challenges, including the purity, oxidation, particle size and dispersion quality.

As a strategic Cooperation Part, Applied Nanotech Inc. (ANI) is developing a line OptomecAerosol inkjet printing solution required Metal Printing Ink. OptomecAerosol inkjet systems are ideal for the ANI's metallic inks printed on flexible solid substrate. Aerosol jet printing system has a wider range of plate viscosity, for a variety of conformal agents, dispersants, additives and copper filler applications. Optomec and co show how to combine ANI ANI Metal ink and use a simple sintering system, in a variety of metal substrates to provide excellent trace.

These metal inks and flexible substrate has a very good compatibility, the flow smooth for use in Optomec system. Users can deal with these inks in the air, without the use of foreign inert gases; the ink drying temperature below 100 degrees Celsius, and show a stable final metal conductive trace, thereby ANI / Optomec looking for complete solutions become metallic ink printing ideal solution.

Load as expanding the scope of ANI and the creation of superior quality inks copper nanoparticles dispersed, therefore, copper nanoparticle ink to be used in carrying out initial tests. Through the use of nanoparticles to produce enough copper production technology patents, ANI has achieved more than a breakthrough. The characteristics of copper nanoparticles have the book, and includes selected ink formulation conformal agents and dispersants.

These nanoparticles of copper inks a big advantage is that they can be fired quickly by electromagnetic radiation, such as the use of laser in air at room temperature continued to provide metal conductive trace, and to achieve micro-European? Cm within the lower resistivity.

These conductive metal can be firmly attached to a variety of flexible substrates. That the first implementation of the Aerosol Jet printing, post-implementation of the simple addition of sintering process for manufacturers in a wide range of electronic printed circuit substrate provides a fast and economical way. Optomec system can be configured and used organic printing Solvent Based and water based conductive metallic inks.

Optomec system can be increased slightly in the distribution rate of 0.25 per second, passing a micron to 5 micron size aerosol droplets, and can print 10 micron to 150 micron. Using ANI copper ink, can print on glass substrate 30 microns wide copper.

Optomec ANI ink system and can also be used Captain (polyimide) substrate, and generate 60 microns wide and 8 micron thick copper sintering.

ANI ink can firmly adhere to Captain basement. Optomec system has a large viscosity range (0.7 cps to 2500 cps range), for fast printing and sintering of metal and metal paste inks, printed electronics industry to meet the wide range of future applications.
