Latest Patents
Aoyagi's latest patents focus on advanced rolled copper foil designs. The first patent describes a rolled copper foil that features a specific crystal grain alignment. This alignment is characterized by a normalized intensity of {200} plane diffraction of a copper crystal, which is measured through X-ray diffraction pole figure analysis. The patent specifies that the ratio of maximum normalized intensity values at different angles must meet certain criteria to ensure optimal performance.
The second patent elaborates on a manufacturing method for rolled copper foil that undergoes recrystallization annealing after the final cold rolling step. This method ensures that the crystal grain alignment meets a defined ratio of normalized average intensities, which is crucial for the foil's structural integrity. The process involves controlling the total working ratio during the final cold rolling to be 94% or more, along with specific working ratios per pass.
