Domestic aluminum nitride ceramic substrates gradually mature, domestic substitution for imports accIssuing time:2022-07-02 13:49 According to statistics, the global market value of AlN ceramic substrates reached 340million yuan in 2019, and it is expected to grow to 620million yuan in 2026, with a compound annual growth rate of 8.4%. Market growth and market demand are increasing, so why is the market growth of aluminum nitride ceramic substrate so high? Can China's domestic aluminum nitride ceramic substrate really replace most imports? Let's share the reason and the current market situation. 1、 Aluminum nitride ceramic substrate has outstanding advantages and is widely used 1. Aluminum nitride ceramic substrate has outstanding heat dissipation and a wide range of applications Aluminum nitride ceramic substrates are widely used in many fields, including automotive electronics, optoelectronic communications, aerospace, consumer electronics, led, rail transit, new energy and so on. However, due to the influence of production process, technical level, market price and other factors, the application scope of aluminum nitride ceramic substrates in China is still relatively narrow, mainly in the field of high-end manufacturing. Compared with alumina ceramic substrate, aluminum nitride ceramic substrate has excellent performance. With the continuous improvement of market requirements for substrate performance, China's aluminum nitride ceramic substrate industry has broad development space in the future. 2. Aluminum nitride ceramic substrate mainly has the following characteristics and advantages: (1) High thermal conductivity (180w/ (m · K) ~260w/ (m · K), which is more than 5 times that of alumina ceramics; (2) The lower thermal expansion coefficient (4.5-10-6/ ℃) matches the semiconductor silicon material (3.5-4.0-10-6/ ℃); It can effectively reduce the thermal stress caused by thermal expansion. (3) Lower dielectric constant means less dielectric loss and more stable performance (4) Excellent insulation performance, ceramic substrate itself is a good inorganic material, with preferred insulation performance (5) Excellent mechanical properties, higher flexural strength than Al2O3 and BeO ceramics, and can be sintered under normal pressure; (6) Heat resistance and corrosion resistance of molten metal 2、 The technical capacity and production capacity of domestic aluminum nitride ceramic substrate manufacturers are maturing, and localization is accelerating 1. At present, the international aluminum nitride ceramic substrate is developed earlier and more high-end abroad At present, the world's high-end aluminum nitride ceramic substrates are mainly concentrated in foreign countries, such as the United States, the United States, Japan and Germany China and other countries are the world's major electronic component production and R & D centers, far earlier than China. Many enterprises in Japan have developed and produced aluminum nitride ceramic substrates. At present, Japan is the largest producer of aluminum nitride ceramic substrates in the world. The companies of AlN ceramic substrate products include maruhiro, special ceramics, sirontek, Sumitomo Metal Industry, Fujitsu, Toshiba, NEC, etc. At the current stage, aluminum nitride enterprises with high popularity include maruhiro, Kyocera, Japanese precision ceramics, special ceramics, Germany sirontek, coraynictechnologylimited, Zixin purple core semiconductor, etc. Among them, imported brands mainly compete in the high-end market, and local manufacturers mainly compete in the middle and low-end market. At present, the production technology level of aluminum nitride industry in China needs to be improved. Import substitution is still difficult to achieve in the short term, and there is a long way to go to realize the high-end route. 2. Domestic science and technology continue to develop, and the localization trend accelerates With the application of domestic aluminum nitride ceramic substrates in automotive electronics, optoelectronic communications, aerospace, consumer electronics, led, rail transit, new energy, semiconductors, sensors, and other fields, the current technological level continues to improve, driving the rapid rise in the market demand for aluminum nitride ceramic substrates. Attracted by the market prospect, more and more domestic enterprises are laying out the aluminum nitride ceramic substrate market, such as Chaozhou Sanhuan group, Fujian Huaqing Hebei Zhongci electronics, Ningxia eisenda and other enterprises. However, on the whole, at this stage, the production capacity of high-end aluminum nitride ceramic substrates in China is still insufficient, and the products are highly dependent on imports. Although the current situation of importing high-end aluminum nitride ceramic substrates cannot be changed in a short time, domestic enterprises continue to research, develop and produce. It is believed that in the future, the technical level and production capacity will become stronger and stronger, and localization substitution will embark on the accelerated track. At the end of 2021, purple core semiconductor officially joined the processing and production of aluminum nitride ceramic substrate, including aluminum oxide ceramic substrate PCB. Its products cover automotive electronics, semiconductors, LED power modules, transportation tracks, sensors, new energy power supply and other product fields. The company has more than ten years of industry experience in the ceramic circuit board industry. So far, it has more than one year of experience in ceramic substrate processing. Adhering to the purpose of "product quality first", Zixin semiconductor strictly controls the quality and delivery time, provides high-quality products for scientific research institutions and R & D institutions, and also makes its due contribution to promoting the gradual substitution of domestic aluminum nitride ceramic substrates for imports. |
