Yuyang Technology firmly believes that through technological innovation and market demandSeek the combination, in order to promote product upgrades. They have introduced the most advanced SLOT-DIE equipment in the world and produced high-end products with low loss and high capacity, reaching the industry-leading level. In the future, Yuyang Technology will take "building MLCC national brand" as its mission, continue to promote products and services to the sea, and move towards a leading position in the global MLCC market.
In power management chips, Yuyang Technology's 0201 to 0402 specifications are widely used, especially thin 0402, but in the future, higher capacity and more complex packages may be needed to meet the needs of large computing chips. This is for ECP packaging technologyYuyang Technology has been actively responding to new challenges to meet the diverse needs of customers. Copper terminal MLCC is Yuyang Technology's main product, but also an important part of its product strategy.
Located in Yuyang Building, High-tech Park, Nanshan District, Shenzhen, Yuyang Technology has two production bases in South China and East China. Zhou Chunhua pointed out that domestic manufacturers need to shift from the fierce competition in the conventional product market to the research and development and production of high-end products to adapt to the outbreak of high-end market demand such as automotive electronics.
Yuyang technology headquarters is located in Shenzhen Nanshan District high-tech Park Yuyang Building, South China industrialThe factory was established in Yuyang Science and Technology Park, Fenggang Town, Dongguan City (covering an area of 120,000 square meters), and the East China factory was established in Yuyang Science and Technology Park, Chuzhou, Anhui Province.
1, landline generally do not install batteries, through the telephone line connection. It is also possible to plug in an alternating current to provide power. If it is some wireless landline and the like, the wireless landline button wireless handset will have a battery cover on the back, sliding the battery cover can be installed to replace the battery, to provide power for the wireless landline.
2, if it is a wired phone, this is OKYes. Wired landlines do not install batteries, the phone can work normally, but some phones because they carry some extended functions, such as alarm, clock, voice mail, etc., the normal use of these functions need to rely on additional battery power supply, if there is no battery, these additional functions will not be available, but does not affect the landline standby and call.
3, the landline phone itself does not need batteries. Generally using POE (Power Over Ethernet) power supply, you can achieve the basic reception and call function. Directly powered by telephone lines, additional power supply and mainsSeparated, which means the phone works in a blackout.
4, in short, the use of landline phones do not need to install batteries, the previous landline phone if you want to have caller ID must be installed battery can be, and the current technology can achieve this function without batteries. Principle: The telephone switch is DC power supply, each line is allowed to take weak current, as long as the telephone electricity does not exceed the regulation, the telephone can enter the network. Integrated circuit technology has developed, and the energy consumption is relatively low, enough.
5, landline phones do not have to have batteries to use. Some batteries are installed to record time and electricityPhone books and call logs.
6, no need, some phones have a display, the battery is to support it, but it does not matter, but the caller ID what you see. The power outage does not affect the telephone service.
2. The key technology of POE switch is POE power supply technology. POE (Power Over Ethernet) refers to the existing Ethernet Cat.5 cabling infrastructure without making any changes, while transmitting data signals for some IP-based terminals (such as IP telephones, wireless LAN access points AP, network cameras, etc.)This type of equipment provides DC power supply technology.
3, PoE technology is composed of power supply equipment (PSE) and power equipment (PD), through the RJ45 socket to achieve power supply. There are three power supply modes: A (1&2, 3&6), B (4&5, 7&8), and compatible with both (PoH). Mode A is suitable for low-power PD, while Mode B utilizes idle pins to provide additional power. Typically, the A connection is 1&2 negative and 3&6 positive; B follows the reverse rule.
4, technical features The project uses advanced blockchain technology to ensure the fast processing of transactionsAnd security. Among them, smart contracts and consensus mechanisms are key technical components of the project. Smart contracts provide the ability to automate the enforcement of contract terms, while consensus mechanisms ensure the secure and stable operation of the network. POE coins act as a medium of exchange and a governance tool in this ecosystem, providing participants with a new way to exchange and store value.
5. This technique plays a key role in modern information technology. In general, POE is an important part of the development of Internet technology, and it has a wide range of applications, from network management to cloud computing to real-time video transmissionOpen it with support. Remember, POE stands for a smart way to connect and power, which simplifies the deployment and maintenance of network equipment and greatly improves efficiency.
6, metallocene catalyst technical barrier metallocene catalyst as the core of polymerization reaction, foreign enterprises have completed research and development and applied for patent protection. The research on metallocene catalysts in China started late, so it is difficult to select new catalyst systems. CGC catalyst has become a key breakthrough direction, and a number of domestic enterprises have accelerated the pace of research and development, but it is still in the period of technological exploration. (2) α-olefin raw material barrier 1-octene is the key to realizing POE localizationIngredients.
