Film capacitor, film-capacitor film, and method for manufacturing film-capacitor film
A film capacitor that includes a resin layer which has a first surface and a second surface and in which there are particles on at least one of the first surface and the second surface; and a metal layer on the first surface of the resin layer, wherein there are more particles in number on the at least one of the first surface and the second surface of the resin layer than inside the resin layer.
ARTIFICIAL GRAPHITE FLAKE MANUFACTURING METHOD AND PRODUCT THEREOF
The present invention discloses an artificial graphite flake manufacturing method, which uses the PI (polyimide) films as the material; via a stacking step, a first heating step and a second heating step, the PI films are processed to form the artificial graphite flakes so as to increase the lubrication and the hardness, improve the heat conduction for balancing temperature increase and better the smoothness; in addition, via a perforation step, a hole structure is formed on the artificial graphite flakes so as to increase the heat diffusion area and the air permeability of the artificial graphite flakes, and then increase the defect-free rate and the smoothness thereof.
