CFO of Volkswagen: insufficient chip supply will last until 2024
According to Reuters, Arno Antlitz, Volkswagen's chief financial officer (CFO), said in an interview with German daily Boersen Zeitung on Saturday that the supply of semiconductor chips is unlikely to fully meet demand again before 2024. He said that although the bottleneck may begin to ease at the end of this year and the output will return to the level of 2019 next year, it is not enough to meet the growing demand for chips. "The structural supply shortage may not solve itself until 2024," Antlitz said. Antlitz said that the lack of harnesses in Ukraine also led to the loss of some components, although the company is establishing new supplier relationships to purchase components from other countries. When asked how the funds from Porsche's public offering planned for the end of this year would be used to support Volkswagen's finance, Antlitz said that the funds would help fund the software department of the automobile manufacturer and its battery production plan. "Only those who can map out their battery supply chain can have an advantage in the scale of electric vehicles. Protection of the supply chain follows. Porsche's public offering allows us to have greater flexibility in financing," Antlitz said.

Under the background of carbon neutrality, can power semiconductors have a share in the energy storage industry?
The World Health Organization has identified "global warming" as the greatest threat that mankind will face in the 21st century. The emission of greenhouse gases, especially the uncontrolled emission of carbon dioxide from the burning of fossil fuels, is considered to be the main cause of global warming. According to ourworlddata According to the data of www.org.org, the global carbon emissions in 2019 reached 36.7 billion tons. In 2020, China's carbon emissions will exceed 10 billion tons. However, according to the information released by the National Bureau of Statistics, China's power generation will reach 8112.18 billion kWh in 2021. Among them, the thermal power generation with coal as the main fuel still occupies the first place - the total amount climbed to 5770.27 billion kWh, which is about 71.13% of the total power generation in China; The hydropower generation is the second largest, with 1184.02 billion kWh generated in 2021, about 14.6% of the total power generation in China; Wind power generation ranks third, generating 566.7 billion kWh in 2021, accounting for 6.99%; Nuclear power generation is 407.52 billion kWh, accounting for 5.02%; The solar power generation capacity is 183.66 billion kWh, accounting for 2.26%.

High end market of frequency converter is in urgent need of expanding the dawn of IGBT localization
There are more than 300 inverter equipment manufacturers in China, but the strength and scale are uneven, and the main brands are 20 to 30. According to the statistics of Frequency Converter Branch of China Electrical Appliance Industry Association, in 2013, the total industrial output value of 15 enterprises in the frequency converter industry was 6.38 billion yuan, the industrial sales output value was 5.49 billion yuan, and the main operating income was 4.646 billion yuan. In recent years, after years of accumulation, the local inverter brand has gradually expanded its market share, and the market share of imported products has been surpassed by domestic inverter enterprises. However, China's inverter supporting industry is relatively weak, lacking technical advantages, and the high-end market share still lags behind foreign brands.
Methods of Improving SMT Chip Processing Efficiency
1. Handling of mounting procedure The SMT production line is composed of multiple equipment, including screen printing machine, mounting machine, reflow soldering, etc., but the speed of the production line is actually determined by the mounting machine. A SMT production line usually includes a high-speed machine and a high-precision mounter. The former is mainly used to mount chip like components, while the latter is mainly used to mount IC and special-shaped components.
