Explanation

It is used for the production and manufacturing of semiconductor devices, integrated circuits, optoelectronic devices and new types of components in the electronic information industry. The materials with specific requirements is electronic information materials, which is the basis and guide for the development of electronic information industry. It mainly includes semiconductor materials, optoelectronic materials, printed circuit substrates (materials such as copper clad plate), electronic ceramics materials, magnetic materials, piezoelectric crystal materials, electronic welding materials, vacuum electronics and special metallic materials, electronic fine chemicals and other materials. It is characterized by strict technical requirements, large capital investment, great manufacturing difficulty, many varieties, relatively few ft, rapid development and upgrading, and high value added of materials.
