T/UNP 563-2025 Specifications for the Preparation of Photosensitive Polyimide

Scope

Main technical content: This standard specifies the raw materials, equipment, processes, quality control, and file management for the preparation of photosensitive polyimide (PSPI). The main contents include determining the raw materials, clarifying the equipment requirements (reaction equipment, purification and post-processing equipment, stretching and heat treatment equipment, environmental and safety control equipment, quality inspection equipment), technical requirements (raw material requirements, equipment requirements, process requirements, quality control requirements), process flow (raw material preparation, pre-polymerization, grafting photosensitive groups, purification, film formation, imidization, post-processing), quality control (finished product performance, performance testing), and file management (raw material procurement and storage records, production process records, inspection results records, quality control files). It is applicable to the preparation and inspection of photosensitive polyimide.
