Description

technical field [0001] The invention relates to the technical field of microelectronic films, in particular to a laminated heat-resistant electronic film and a preparation method thereof. Background technique [0002] Polyimide (Polyimide, sometimes abbreviated as PI) refers to a class of polymers containing imide rings (-CO-N-CO-) in the main chain, and is one of the organic polymer materials with the best comprehensive performance. Its high temperature resistance is above 400°C, and its long-term use temperature range is -200-300°C. Some parts have no obvious melting point, high insulation performance, dielectric constant of 4.0 at 103 Hz, and dielectric loss of only 0.004-0.007. It belongs to F to H-level insulation. [0003] According to the chemical structure of the repeating unit, polyimide can be divided into three types: aliphatic, semi-aromatic and aromatic polyimide. According to the interaction force between chains, it can be divided into cross-linked type and no...
