Electronics

In these applications and markets we operate

EXAKT for printed electronics
Tremendously adaptable

Applications of printed electronics are extremely diverse – e.g. in fields such as automotive, consumer electronics, textiles or alternative energy solutions. Dispersion is a prerequisite for printing metallic and ceramic particles. It seperates particle agglomerates and enables the wetting of the primary products in a single process step. EXAKT Precision Three Roll Mills are used successfully for medium to high viscosity pastes or master batches which can be specifically diluted to become low viscosity inks if necessary. The result is a highly functional paste which adapts to the function of the component, the substrate and the printing process, whether in screen printing or inkjet printing.

EXAKT for electronic components
Decisive for the function

Complex hybrid systems, such as metal pastes, polymer pastes or solder pastes, are the basis of electronics. These suspensions are crucial for the function of electronic components. They contact or attach components or modules to printed circuit boards, such as multilayer systems and multilayer boards, for example. Suspensions also protect parts and components, e.g. by pouring in silicones and epoxy resins, or are used for so-called encapsulation or packaging. Outstanding results are achieved in all fields with EXAKT Three Roll Mills in the manufacture of a wide range of suspensions.

EXAKT for solar cells
Indispensable in photovoltaics

In the production of conductive silver, aluminum, and copper pastes, as well as other precious metal pastes, EXAKT Three Roll Mills in particular have long been accepted in conventional photovoltaics. Primary particles are not damaged, and flaking or dry trituration of the metal particles does not occur. EXAKT Three Roll Mills also make a significant contribution in the processing of titanium dioxide in dye solar cells, the so-called »dye-sensitized« solar cell. A transparent coating is achieved here. 

EXAKT for optical properties
Solutions for tomorrow

The high processing quality of the EXAKT Three Roll Mills advances the development of future technologies significantly. EXAKT Three Roll Mills achieve excellent results in the production of pastes with optical properties, such as phosphorus pastes for LED production or OLED lighting technology, where very specific requirements are achieved. They are also suitable for an ITO or ITO substitutes for transparent, conductive coatings on flexible substrates, such as plastic films for touchscreens.

EXAKT for batteries, fuel cells, capacitors
Technologies for energy

Specific demands are placed on the processing of slurry for the battery industry and the production of suspensions with carbons for fuel cells and capacitors.

The decisive factor is absolute purity. Contaminants – such as metal and cross contaminations – are avoided with the EXAKT Three Roll Mill. In addition to the formulation, the processing must be adjusted primarily to the morphology, size and structure of the particles. EXAKT Three Roll Mills achieve impressive results, which have already proven themselves in the development of lithium-sulphur batteries and solid oxide fuel cells.

EXAKT for displays & flexible electronics
Paving the way for technological progress

Organic and printed electronics are an integral part of consumer electronics today. The flexible OLED polymer pastes for touch panels or e-paper are the focus of current developments. The high-precision EXAKT Three Roll Mills make a significant contribution to technical progress. They master all the challenges of processing demanding materials such as graphenes, CNTs, carbon nanotubes, for example, in transparent conductive layers as an ITO substitute.
