Low temperature sintered Silver nanoparticle paste

This product, as a mainstream process in the field of printing electronics, achieves the refinement of wiring and better bending resistance of wiring than before in screen printing. Therefore, it is expected to be applied to flexible devices such as smartphones and wearable devices that require a certain degree of bending resistance, as well as to improve the penetration of glass heaters that are expected to further increase demand with the popularity of electric vehicles.

Advantages of a product

1 Silver paste suitable for fine printing below 30um

Generally, in screen printing, the line width of about 50um is considered as the printing limit, but by combining the printing machine and screen plate of Silver nanoparticle paste, it is not only possible to directly print 30um fine wiring on glass that is considered difficult to carry out fine line printing, but also on other substrates such as PET film and ceramic ceramic embryo. It can be used in the glass heater of Alternative fuel vehicle, transparent antenna for 5G and other penetrating electronic devices to improve the performance and productivity.

2. Buckling resistance of printed circuits

The wiring printed on flexible organic substrates such as PET film (with a printing line width of 100) has been demonstrated in a bending test with a bending radius of 0.5mm, which proves that even after 100000 bends, the wire will not break. It is expected to be suitable for flexible devices such as smartphones and wearable devices that require both flexibility and durability.

3 Low resistance value

Under the sintering condition of heating at around 90 ℃, a resistance value below 9 was achieved μ Ω cm, which is also very rare in the low-temperature sintered Silver nanoparticle slurry.

4 Silver nanoparticle paste suitable for screen printing

This product is suitable for printing silver paste with nano and submicron silver particles used in screen printing, which is more common in printing electronic technology. As it is more suitable for screen printing, the screen printing performance is improved by controlling particle size, selecting solvent, adding macromolecular compounds, etc., and Silver nanoparticle slurry with strong bending performance is successfully developed.
