The development of science and technology enables people to get in touch with some new things faster. As a symbolic product of today's information society, smartphones are often encountered in people's life and work. Smartphones are consumer electronics products, and the replacement speed Soon, its performance and supporting equipment will also keep up with the pace of the times.
The technology of our modern society is constantly developing rapidly, and more and more high-power electronic devices and electrical appliances appear in our market. With the continuous improvement of scientific and technological requirements, while the refinement and miniaturization of electronic equipment, the power is also continuously increasing, and the heat conduction requirements of devices are getting higher and higher. The conventional heat conduction materials in the market can no longer solve the heat conduction problem well. The research and development of new heat-conducting materials for microelectronic devices has become a key issue that needs to be challenged urgently in the heat-conducting industry.
Electronic products are often encountered in people's life and work, and it is known that electronic products will generate heat when they are used, and excessive temperature will affect the electronic components in electronic products, and most electronic components cannot Withstand high temperature, so the heat dissipation design of electronic products is related to the normal use of electronic products.
If you want to ask what is the most frequently touched object in people's life? People's first impression is the mobile phone. Some people say that from turning off the mobile phone alarm clock in the morning to setting the mobile phone alarm clock at night, mobile phones accompany people's day, and electronic devices represented by mobile phones are often in contact with people in their lives and work.
5G technology has brought many conveniences to people. The application of 5G can ensure low latency and high download rate of communication data, and improve the coverage area. Heat dissipation has always been one of the main challenges faced by 5G.
Carbon fiber thermal pads, some companies call them anisotropic thermal pads, can be several times or even ten times higher in thermal conductivity than traditional thermal silica sheets. The reason lies in the difference in thermal conductivity components.
Many people have come into contact with these problems. The more high-tech electronic products, the more serious the impact of temperature on them, and the heat generated when electronic products are running is unavoidable. , so we can only do a good job of heat dissipation.
There must be a reason for the problem. The key to solving the problem lies in whether the essence of the problem can be clarified. Electronic products refer to related products that consume electric energy, such as mobile phones, TVs, radios, electric energy, smart watches, etc. During their use, It will inevitably generate heat. If the heat is severe, it may affect the use of electronic products, so we need to pay attention to this problem.
Most of the causes of abnormal performance of electronic equipment are too high temperature inside the equipment. The reliability of electronic equipment is closely related to temperature. Some studies have shown that when the ambient temperature increases by 10°C, the life of components will be reduced by half. This is the famous 10°C rule, which shows how much the influence of temperature and electronic equipment is.
The situation that the temperature is too high causes the mobile phone to freeze and crash from time to time. A common problem with electronic products.
Many people know that electronic equipment will generate heat when it is working. While electronic components are mainly used to consume electric energy, a large part of the energy will be converted into heat and dissipated. After the electronic equipment generates heat, the temperature inside the equipment will rise rapidly. High temperature has always been one of the factors that affect the performance and service life of electronic components, so if the heat is not dissipated in time, it may cause electronic components to fail, thus affecting the stability of electronic equipment.
Large electrical equipment is everywhere in people's life and work, such as outdoor communication cabinets. Outdoor communication cabinets are widely used in power systems and communication systems, and are one of the foundations of today's network communication technology. If the outdoor communication cabinet fails, it may affect people's normal work and life, so ensuring the normal operation of the outdoor communication cabinet is the key.
For an electrical equipment, the design and construction of the heat dissipation coefficient is very important. Heat generation is common to all electrical equipment, because heat will be generated when the current passes through the resistance. Since it cannot be avoided, it should be improved. The construction enables the device to operate at a controlled temperature.
Thermal management is no longer just about temperature values; it's also about chemical cleanliness. In many high-reliability systems, non-silicone thermal pads have evolved from a niche option to a design necessity because silicone-based thermal materials can silently contaminate sensitive components. Low molecular weight siloxanes in silicone gap fillers can migrate ("outgas") under heat and potentially condense on optical devices, corrode electrical contacts, or hinder proper wetting of adhesives and conformal coatings.
