1. The scientific and technological field of the project: This project belongs to new materials mdash; special fiber materials mdash; alkali-free glass fiber. Our company's electronic-grade glass fiber cloth belongs to the category of alkali-free glass fiber. It is a fine product among alkali-free glass fiber. It is specially used in printed circuit substrate materials. It is one of the main raw materials for printed circuit substrates and plays a role in insulation reinforcement, expansion and shrinkage and support. 2. Technical innovation content: 1. The processing equipment adopts fiber opening technology, which changes the structure of the glass fiber cloth through the impact of high-pressure water flow, makes the yarn bundle loose, and makes the entire structure uniform. 2. Control the edge sealing width below 5mm to avoid wasting the resin raw materials in the resin tank when the electronic grade glass cloth with feathered edges is glued downstream, and it can also prevent the feathered edges from bringing hairiness into the resin tank to ensure the cleanliness of the resin. After edge sealing, 0.4% of the CCL impregnated resin consumption can be saved. 3. Use epoxy resin with good compatibility with the resin system as the edge sealing material to avoid glue ejection during downstream immersion. Silane coupling agent is added to increase the strength of the end and reduce defilement abnormalities. 4. Use a cutting waste suction device to clean up debris and waste silk on the surface of the cloth to improve the cleanliness of the product. 5. Adopt movable trimming processing equipment and double-sided coating equipment to increase the requirements for trimming width, adapt to the requirements of more customers, enhance trimming quality, and reduce abnormalities. 3. Intellectual Property Rights and Application Promotion The products of this project have applied for 1 invention patent and 5 utility model patents. This product is of good quality, environmental protection, and good market promotion and application.
