Abstract:
Disclosed herein is a polyimide film having inorganic particles. The polyimide film is 12-250 μm in thickness. The polyimide film includes about 50-90 weight parts of polyimide and about 10-50 weight parts of the inorganic particles. The particle size of each of the inorganic particles is about 0.1 μm to about 5 μm. The polyimide film is characterized in that the thermal expansion coefficient is equal to or less than 30 ppm/° C. in any direction, the difference between two thermal expansion coefficients in two mutually perpendicular directions on the film surface is less than 10 ppm/° C., and the Young's modulus of the polyimide film is greater than 4 GPa in any direction. The dimensional stability of the polyimide film measured by the standard of IPC-TM-650 is less than 0.10% in any direction. A method for manufacturing the polyimide film is disclosed as well.
