Abstract
Novel materials and devices can remove small defects from long rolls of flexible electronics material while they are in continuous motion. The cleaning materials are designed to remove small particles without transferring defects or damaging the flexible electronics. The device generally consists of variable speed, motor-driven cylinders mounted on moveable brackets. The cylinders are capable of matching the speed of the cleaning material such that the cleaning material is always in contact with the web roll to be cleaned. The brackets are capable of rotating so the same material can be used more than once. Another material is used to remove debris from the cleaning material. A similar device consisting of motor-driven cylinders and moveable is used to apply the debris removal film to the cleaning film, allowing the cleaning film to be used multiple times.
