Special circuit boards are circuit boards with special functions or special purposes. With the continuous development of technology, there are various kinds of special circuit boards in the market, such as high-speed circuit boards, high-frequency circuit boards, thick-copper circuit boards, etc. The research and application of special circuit boards have been a hot topic in the electronic field.
The research and application of special circuit boards have always been a hot topic in the field of electronics. At present, China has made some breakthroughs in the research of special circuit boards, for example, in the area of high-speed circuit boards, domestic enterprises have been able to produce world-leading 40G, 56G and 112G high-speed circuit boards. In terms of thick copper circuit boards, Chinese enterprises have also been able to produce 30oz, 40oz and 50oz thick copper circuit boards with high reliability. In addition, there are many other types of special circuit boards being researched, such as flexible circuit boards, high-reliability circuit boards and so on.
The research of special circuit boards mainly includes data research, process design, performance testing and so on. Among them, data research has a great impact on the performance of special circuit boards. For example, for high-speed circuit boards, data such as dielectric constant, dissipation factor, glass transition temperature, etc. will have an impact on the characteristics. For flexible boards, characteristics such as flexibility and tensile strength are also important considerations. In addition, process design is also the focus of research on speciality circuit boards, and continuous innovation of the corresponding process technology can also enhance the performance of speciality circuit boards.
The application of special circuit boards is closely related to the development of the electronics industry. With the promotion of 5G technology and access to higher data transmission speeds, high-speed circuit boards will become the mainstream of development. With the popularity of new energy vehicles and the acceleration of electrification, high-reliability circuit boards will be widely used in the field of intelligent vehicles. In addition, the development of big data, cloud computing and other emerging technologies also put forward higher requirements for special circuit boards, which also adds the need for research and application of special circuit boards.

Special engineering plastics are high-performance engineering plastics with long-term use temperature above 150°C. They are the third generation of plastics after general-purpose plastics and engineering plastics. They are the third generation of plastics developed after general-purpose plastics and engineering plastics. They have the advantages of heat resistance, insulation, corrosion resistance and high mechanical strength. The main varieties are polyphenylene sulfide, polyamide, polyhydrazone, aromatic polyamide, polyarylate, polyphenylene ester, polyetheretherketone, liquid crystal polymer and fluorine resin.
The laminates industry is located in the middle of the whole PCB industry chain, providing raw materials for PCB products. Laminates are made of electronic glass fibre cloth or other reinforcing materials impregnated with a resin binder, dried, cut, stacked into blanks, laminated with copper foil on one or both sides and hot pressed to form board-like materials. It is mainly used in the production of printed circuit boards (PCBs), and plays the role of interconnection, insulation and support for PCBs. The upstream of the industrial chain is electrolytic copper foil, wood pulp paper, glass fibre cloth, resin and other raw materials, the downstream of the PCB products, end-use industries such as aviation and aerospace, automotive, home appliances, communications, computers, and so on.
Ultrasonic Electronics said that the current global PCB manufacturing enterprises are mainly located in China, Taiwan, Japan, Korea, Europe, the United States and other regions.From the regional distribution of output value, the centre of gravity of the PCB industry has shifted to Asia,China's PCB output value accounted for more than 50% of the world.Ultrasonic electronic printed circuit board products in the PCB industry has a wide range of applications,by a single industry has less impact. In this case, more manufacturers,the industry is relatively fragmented, market concentration is not high,and market competition is sufficient.
From the division of labour in the global industrial chain, ultrasonic electronics is in a period of explosion,the most important of which is the relaxation of restrictions on personal low-altitude aviation in China,which will have the opportunity to stimulate the market for airborne products exponential growth.The advancement of smart manufacturing will lead to another growth period for industrial control machine products.After the AIOT market expands to more application scenarios, the requirements for high-performance products in the smart home field will also be comparable to those of industrial control machine products,which are also the target market for ultrasonic electronics.
As an important part of the electronics industry,the research and application of special circuit boards have always attracted much attention. It is believed that under the continuous technological research and development and the improvement of technology, the performance and application of special circuit boards will be more and more extensive.
