Electronic components in circuits mainly include diodes, transistors, thyristors, and field-effect transistors, among which diodes and transistors are the most commonly used. Correctly determining the quality of diodes and transistors is one of the basic skills electricians should master. 1. Measurement of Diodes 1. Usually, use the Rx100Ω range or Rx1kΩ range of a multimeter to measure diodes with lower withstand voltage and smaller current. 2. When measuring the forward and reverse resistance of a 2AP9 type diode with a multimeter's resistance range, the Rx100Ω range should be selected. If the forward resistance value of the diode is between tens to hundreds of ohms, and the reverse...

Since Anker released the world's first GaN charger on October 25, 2018, officially introducing GaN into the consumer electronics field, major GaN manufacturers have been involved in related products in just a few years. Currently, the GaN consumer electronics market is a red ocean with increasingly fierce competition. Faced with the current application status of GaN in the consumer electronics field, relevant enterprises have begun to seek new incremental markets, and the application of GaN technology has gradually extended to other application scenarios such as new energy vehicles, photovoltaics, and data centers. The special value of GaN is continuously being released in multiple fields beyond consumer electronics。

From January to February, the added value of China's integrated circuit manufacturing industry increased by 21.6% On March 18th, the State Council Information Office held a press conference on the operation of the national economy in January and February 2024. The spokesperson of the National Bureau of Statistics, Chief Economist, and Director of the Department of Comprehensive Statistics of the National Economy stated at the meeting that in the first two months of this year, new driving forces and advantages have been continuously cultivated and strengthened, and there have been new developments in all aspects. Industries with high-tech, high-efficiency, and high-quality characteristics are developing well. Specifically, in January and February, the added value of equipment manufacturing industry above designated size increased by 8.6% year-on-year, which was 1.6 percentage points higher than the average level of all industries above designated size; The added value of high-tech manufacturing industry increased by 7.5%, among which the added value of semiconductor device specialized equipment manufacturing industry increased by 41.2%, integrated circuit manufacturing increased by 21.6%, and intelligent unmanned aerial vehicle manufacturing increased by 18.2%. Since 2024, the development of China's integrated circuit industry has continued to improve. According to recent data released by the General Administration of Customs, the export volume of integrated circuits in China reached 39.41 billion units in January and February this year, a year-on-year increase of 6.3%, and the export value reached 160.71 billion yuan, a year-on-year surge of 28.6%.

The semiconductor industry has become one of the hot topics of discussion at the National People's Congress and Chinese People's Political Consultative Conference.

Recently, foreign media reported that Apple COO Jeff Williams and Vice President in charge of automotive projects Kevin Lynch have announced to employees that the Apple automotive project will begin to wrap up, and most of the employees in the automotive team will be transferred to the AI department led by John Gyanendra. According to data, Apple launched the Titan car manufacturing plan in 2014, but the plan was halted multiple times during this period, and the car manufacturing business officially ended this year. Several industry representatives in China have expressed their views on Apple's decision. Among them, Li Xiang, CEO of Ideal Auto, recently stated on a public platform that Apple's decision to abandon car manufacturing and focus on artificial intelligence is an absolutely correct strategic choice, and the timing is also appropriate. Firstly, by developing artificial intelligence into toC, Apple will become a $10 trillion enterprise; If artificial intelligence loses, Apple will become a trillion dollar enterprise. Artificial intelligence will become the top entry point for all devices, services, applications, and transactions, and it will be Apple's ultimate battle. Secondly, it has been made into a car and achieved great success. Apple's market value will increase by $2 trillion, but the necessary condition for the success of cars is still artificial intelligence. The electrification of automobiles is the first half, while artificial intelligence is the final. The artificial intelligence extended by mobile phones is bits, the artificial intelligence of cars is atoms, and artificial intelligence spans both the digital and physical worlds. Finally, Li Xiang stated that the three necessary conditions for the success of artificial intelligence include talent, data, and computing power.
