Latest Patents
One of Uemura's latest patents is a polyimide film that boasts superior heat resistance, rigidity, and high-frequency properties. This film is designed to avoid curling issues even when various functional layers are laminated through heating. It serves as an excellent substrate film, demonstrating high thermal degradation stability for electronic parts. The film has a planar orientation coefficient ranging from 0.79 to 0.89, as measured by X-ray diffraction. Additionally, it maintains a minimal difference in surface planar orientation and a curling degree of no more than 5%, achieved through the imidation of a specific polyimide precursor film.
Another significant patent involves an apparatus and process for producing polymer films, particularly polyimide films. This innovative apparatus performs drying and heat treatment using a tenter-type feeding system that mitigates deformation issues near the pores where pins penetrate. The design includes a mechanism to cool the pin temperature to below 180°C during the piercing process, ensuring the integrity of the film. Individual pins can be arranged uniformly, enhancing the efficiency of the film production process.
