Film Width Measurement on R2R Process

 

In the field of electronic devices, Roll-to-Roll (R2R) processing is a method of producing flexible and large-area electronic devices on a roll of plastic film or metal foil.

R2R is a family of manufacturing techniques involving continuous processing of a flexible substrate that is transferred between two moving rolls of material in which additive processes can be used to build film structures in a continuous manner.

R2R is an important class of substrate-based manufacturing processes applied nowadays for EV market lithium-ion battery (LIB) such as:

• Metal foil (aluminium and copper) manufacturing
• Plastic film for separator production
• Printed/Flexible thin-film batteries electrodes (cathode and anode)
