Polyimide dry film and application thereof |
| abstract |
A polyimide dry film including a substrate and a polyimide layer is provided. The polyimide layer contains (a) a polyimide precursor or soluble polyimide and (b) a solvent. The solvent includes a hydrophilic solvent and a hydrophobic solvent and the weight ratio of the hydrophilic solvent to the hydrophobic solvent is in the range from about 0.05 to about 2. The polyimide dry film of the present disclosure has water absorbability and is relatively stable even in the presence of water, and the surface thereof is not sticky. The resulting polyimide has excellent physical properties and can be used in the process in which water or an aqueous solution is involved to form a coverlay with excellent physical properties. |
