What is Roll-to-Roll processing?

Roll-to-Roll (R2R) is a production technique used to create electronic devices on a flexible substrate material that is transmitted from one cylinder to another. When the substrate winds over multiple cylinders, a number of production operations can be performed. The Roll-to-Roll can also be used as a web processing or processing of the winch on the winding.

Roll-to-roll processing operation usually includes several cylinders called web, around which the substrate is routed by a number of production operations. These rollers can be oriented so that the substrate is oriented horizontally, vertically or diagonally because it is transferred from one to another. On the final cylinder, sometimes called Take-up Roller, the substrate is rolled up rather than to be directed to another cylinder.

The substrates used in the processing of R2R can be made of different materials depending on the applications and steps of processing connected to the production. TIC Plasyfilms are desirable for their transparency, flexibility and houžEvolution, but are often susceptible to degradation and dimensional distortion at high temperature. If transparency is not required, stainless steel foils may be selected as they tolerate higher temperatures than plastics. Other materials such as aluminum and copper alloys can also be used.

On a flexible substrate, the patterns of the circuit

can be created in different ways. Some such production lines use ink technology to insert material on the substrate. This process is similar to the ink printer ink ink on paper. Some devices use photolitography, using light to etch the pattern on the substrate, which can then be filled with another material. Other techniques using ultraviolet light, lasers, etc. can also be used to print the substrate by electrical circuits.

A number of other menu of U -deacturing can also be done using R2R processing. In addition to determining patternsThe circuit can be made steps such as cutting, laminating, placing labels, cleaning and more. The thermal seal and the use of various coatings can also be included in the Roll-to-Roll processing operation.

The benefits of Roll-to-Roll processing include a high degree of production and revenues. Since it allows you to automatically produce devices in bulk quantities, this technique can help reduce production costs through savings in the range. Although the initial capital costs may be high to set up such a system, these costs can often be obtained through economic benefits during production.

Many products contain electronics made with cylinder processing. These include consumer electronics such as mobile phones and computers, home appliances and even home exercise equipment. Equipment used by the medical industry that includes such electronicity of oxygen blood monitors, fans and interactive controls for medicalá displaying device. Advanced architectural functions such as optical closures that can move from translucent to transparent

Roll-to-roll processing was particularly influential in the development of thin films of solar articles. Using a fraction of the conventional solar panel material, thin film solar cells increase more attractive solar energy on the energy market. It is their processing on flexible material in the war facility helps to reduce their historically high costs. Their thin profile also makes them aesthetically attractive for energy production than bulky conventional panels. As the processing of thin film cells, more steps are automated, leading to a reduction in prices that make this technology more economically competitive.
