Electronic ceramics refers to ceramic materials used in the electronics industry to prepare various electronic components and devices. It uses artificially refined inorganic powder as raw material, achieves specific properties through structural design, precise stoichiometry, appropriate molding methods and firing systems, and is processed to make it meet the inorganic non-metallic materials with required dimensional accuracy.
Electronic ceramics are widely used in the electronics industry to prepare various electronic components, and are indispensable basic materials for the manufacture of electronic components.
Overview of the electronic ceramic industry
The upstream of the electronic ceramic industry includes electronic ceramic basic powder, formula powder, metal materials, chemical materials, etc.;
Its midstream is electronic ceramic materials, which mainly include: ceramic shell, ceramic base, ceramic substrate, chip multilayer ceramic capacitor ceramic, microwave Dielectric ceramics etc.
The downstream of electronic ceramics is mainly electronic components, which are ultimately used in end products. Its application fields are very broad, including optical communications, wireless communications, industrial lasers, consumer electronics, automotive electronics, etc. It is mainly used for oscillation in various electronic machines. , coupling, filtering and other circuits.
Compared with traditional materials, ceramic materials have excellent properties such as high temperature resistance, wear resistance, corrosion resistance, and light weight.
Electronic ceramic products are an inseparable and important part of high-end semiconductor devices. They are an important bridge connecting chips and external system circuits, directly affecting the performance, quality and reliability of devices. They can be widely used in communications, high-power lasers, automotive electronics , consumer electronics and other fields.
Electronic ceramic housing for communication devices
a. Optical communication device housing
In recent years, China has vigorously called for and advocated the Broadband China Strategy and the Internet +Action Plan, which has promoted the rapid development of the Internet industry and cloud computing, and has prompted the continuous increase in the demand for data centers across the country.
The data center is dominated by 100G optical modules, and the communication within the data center, between data centers, and between different customer data centers all generate demand for optical communication devices.
The 5G era is approaching. With the explosive data transmission and storage in the field of optical communication, the use of bandwidth has been greatly increased. The mainstream of optical communication devices is 100G, and it will continue to develop to 400G.
With the acceleration of infrastructure construction in China’s optical communications industry, the optical communications device industry has gradually moved to China, and China has become an important global production base. The world’s major optical communication device companies have transferred their main production and R&D bases to China.
At present, many internationally renowned industry giants have set up R&D, procurement centers or factories and other branches in China. China’s optical communication device manufacturers have developed rapidly driven by demand and have invested in the production of 100G optical communication devices/optical modules.
Therefore, with the growth of the market size of optical communication devices and modules, and the accelerated layout of Chinese foreign optical communication device companies in the field of mid-to-high-end optical communication devices, the demand for optical communication device housings, one of the key components, has also increased.
b. Infrared detector shell
The electronic ceramic shell has the advantages of good air tightness and can provide good physical support, electrical path, and thermal path. From the perspective of product manufacturing, compared with metal shells, electronic ceramic shells are used in infrared detectors, which can significantly reduce the volume and weight of the detectors and reduce manufacturing costs.
With the continuous expansion of infrared detectors in new application fields such as electric power, construction, law enforcement, fire protection, and vehicles, their consumption in the civilian market will grow rapidly.
As a supporting component of infrared thermometers, infrared detector housings play an active role in the prevention and control of the new coronavirus pneumonia epidemic in China. The surge in demand for infrared thermometers will also rapidly promote the application market of infrared detector housings. Rapid growth.
c. Wireless power device housing
Wireless power devices include silicon bipolar transistors, LDMOS power transistors and third-generation semiconductor GaN power transistors, etc., which are the core devices of mobile communication base stations and mobile terminals.
With the development of 4G/5G systems, the number of base stations will also increase dramatically, and LDMOS power transistors and third-generation semiconductor GaN power transistors will become the most competitive advanced devices for base stations.
In addition, with the frequent launch of Beidou satellites, terminal applications of Beidou navigation systems such as handheld, vehicle-mounted, airborne, ship-mounted, and embedded are becoming more and more popular. For each terminal to communicate with space satellites, the wireless power device in its transmission channel is crucial.
Conclusion
After years of hard work, China has made great achievements in the field of wireless power device technology. However, due to cost, batch production capacity, consistency and other reasons, wireless power devices mainly rely on imports in the popularization and application of communication base stations and Beidou terminals, and Chinese communication equipment manufacturers purchase imported devices in large quantities. The housing of wireless power devices is a key component of wireless power devices, and the explosion of wireless power devices in China will surely drive the demand for its supporting housings.
