Abstract
The advent of roll-to-roll (R2R) manufacturing is a significant breakthrough as a high-throughput and low-cost technology for continuous fabrication of functional substrate film for various applications, especially for mass production of printed electronics and functional optical film. Structured roller mold utilized in R2R manufacturing is the essential component, which transfers the micro-feature or pattern from the mold onto the polymer film. It requires high-profile accuracy, excellent surface quality, and consistent feature uniformity; hence it is usually fabricated by micromachining technologies. This chapter emphasizes on micromachining of roller mold for R2R manufacturing process, and fabrication technology of two major types of roller mold are mainly discussed: gravure roller mold and embossing roller mold. Recent advances in micromachining of these two types of roller mold is addressed, particularly on novel machining process invented for enhanced film performance and complex micro-features generation. Measurement and characterization of both the machined roller and R2R manufactured film are also discussed in detail.
