How is PI Coated onto a Glass Substrate? How is PI coated onto a glass substrate? How is PI liquid converted into PI film? The following is a breakdown of the specific process: 1. Glass substrate cleaning: Generally, EUV cleaning is performed first, followed by brush cleaning, high-pressure water vapor spray cleaning, and finally A/K drying. EUV cleaning: By irradiating the surface of a glass substrate with 172nm [...]
