electronic chemicals refer to fine chemicals and materials specifically designed for the electronics industry, namely integrated circuits, electronic components, printed circuit boards, industrial and consumer machine production and packaging. common electronic chemicals include substrates, photoresists, plating chemicals, packaging materials, high-purity reagents, special gases, solvents, pre-cleaning dopants, solder masks, acids and corrosives, adhesives and auxiliary materials for electronics.
electronic chemicals are high-tech products that combine electronic materials and fine chemicals. they mainly include integrated circuits and discrete devices, capacitors, batteries, resistors, optoelectronic devices, printed circuit boards, liquid crystal display devices, picture tubes, televisions, computers, recorders, video cameras, laser discs, stereos, mobile communication equipment, fax machines and other electronic components, parts and components and various fine chemical materials for the production and assembly of complete machines. electronic chemical materials and downstream components are the foundation and forerunner of the electronic information industry and are at the front end of the electronic information industry chain. they are the basis for the development of end products in the fields of information and communication, consumer electronics, household appliances, automotive electronics, energy-saving lighting, industrial control, aerospace and military industry.
with the development of technological innovation, the application field of electronic chemicals has been expanding and has penetrated into various fields of national economy and national defense construction. without high-quality electronic chemicals, it is impossible to manufacture high-performance electronic components. to a certain extent, electronic chemicals determine or influence the development and progress of downstream and terminal industries, and are of great significance to the upgrading of domestic industrial structure, national economy and national defense construction. the ministry of industry and information technology pointed out that during the "eleventh five-year plan" period, china must vigorously develop the electronic materials industry, accelerate industrial restructuring and optimization, narrow the gap between electronic materials and foreign advanced levels, improve the domestic independent supporting capacity, and provide strong support for the development of the electronic information industry.
noa has a central laboratory of nearly 30,000m2, with organic, inorganic, physical and chemical, thermal analysis, mechanics, reliability, combustion and weathering laboratories. we can provide one-stop analysis and testing services for raw material quality control, composition analysis, foreign matter analysis, performance testing and reliability testing for electronic chemicals.
noa can provide services such as composition analysis, failure analysis, comparative analysis and foreign matter analysis for electronic chemicals through large precision instruments such as spectroscopy, chromatography and mass spectrometry, using multivariate analysis tools to help customers analyse the chemical composition and composition content of samples, or qualitative and quantitative analysis of specified components and content according to customer requirements, identifying raw materials, additives, specific components, content and foreign matter composition and other analysis services.
