Flexible Printed Electronics

Flexible Printed Electronics

Printed electronics is a set of printing methods used to create electrical devices on various substrates. Printing typically uses common printing equipment suitable for defining patterns on material, such as screen printing, flexography, gravure, offset lithography, and inkjet. By electronic industry standards. Electrically functional electronic or optical inks are deposited on the substrate, creating active or passive devices, such as thin film transistors; capacitors; coils; resistors. Printed electronics is expected to facilitate widespread, very low-cost, however still good-performance electronics for applications such as flexible displays, smart labels, decorative and animated posters, and active clothing that do not require high performance.

The term printed electronics is often related to organic electronics or plastic electronics, in which one or more inks are composed of carbon-based compounds. These other terms refer to the ink material, which can be deposited by solution-based, vacuum-based or other processes. Printed electronics, in contrast, specifies the process, and, subject to the specific requirements of the printing process selected, can utilize any solution-based material. This includes organic semiconductors, inorganic semiconductors, metallic conductors, nanoparticles, and nanotubes.

For the preparation of printed electronics nearly all industrial printing methods are employed. Similar to the conventional printing, printed electronics applies ink layers one atop another.  So, the coherent development of printing methods and ink materials are the field’s essential tasks.  The most important benefit of printing is fair-cost volume fabrication. The lower cost enables use in more applications.  An example is RFID-systems, which enable contactless identification in trade and transport. In some domains, such as light-emitting diodes printing does not impact performance.  Printing on flexible substrates allows electronics to be placed on curved surfaces, for example, printing solar cells on vehicle roofs. In contrast, conventional semiconductors must justify their much higher costs by providing much higher performance.  For many commodities manufacturing, the performances of printed electronics are satisfactory for many daily life purposes.

Our devices which can help in these applications are: All types of contact angle meters used for solid surface, SITA SurfaSpector, A60, A100, A200, A300, RSD100, for liquid or solutions: SITA tensiometers Dynotetser, t15 Plust100SITA ConSpector, SITA Cleanline ST and for surface cleanliness checking and validation: SITA CleanoSpector, SITA FluoScan 3D, SITA Cleanline CI, Viscometer, Rheometer (please discuss with our experts), etc.
