BYD: refresh the global new energy bus north extension map, only more than 100 kilometers from the Arctic Circle

BYD delivered the city's first all-electric bus to Pitao, a famous port city in northeastern Sweden. It is the first of 13 buses purchased from BYD by Nordic public transport operator Nobina Group in May last year. All of the buses will run on Pitao bus lines this summer. BYD said the city is located at 65 degrees 31 'north latitude, just over 100 kilometers from the Arctic Circle (66 degrees 34' north latitude). This delivery marks the new record of the northernmost operating line of BYD electric bus, and at the same time, it has refreshed the northern extension of the global footprint of new energy vehicles. The vehicles are made at BYD's Hungarian plant in Europe. So far, Nobina has ordered more than 300 electric buses from BYD, of which 160 have been put into operation. In Europe, BYD has won more than 1,800 orders for pure electric [...]

Toshiba develops new packaging technology for silicon carbide power modules to improve reliability and reduce size

Toshiba has developed packaging technology for silicon carbide (SiC) power modules that doubles product reliability while reducing package size by 20%. Compared with silicon, silicon carbide can achieve higher voltage and lower loss, and is widely regarded as a new generation of materials for power devices. Although currently used mainly in train inverters, it will soon be widely used in high-voltage applications such as photovoltaic power systems and automotive equipment. Improve reliability through silver sintering technology Toshiba develops new packaging technology for silicon carbide power modules to improve reliability and reduce size Reliability is the main limitation of silicon carbide devices. In the application of high voltage power module, not only the semiconductor chip, the package itself must have a high degree of reliability. Toshiba has achieved its goal of effectively improving package reliability by soldering chips using a new silver (AG) sintering technology. In current silicon carbide packages, increasing [...]

Panasonic stopped producing TVs in Japan and moved all to overseas factories

Panasonic announced on the 11th that the group has stopped producing TV sets in Japan and will focus on overseas production in the future. At the end of March, the last TV set produced by Japan's Panasonic rolled off the assembly line at a factory in northern Tokyo. Panasonic officials stated that the high cost of producing TVs in small batches in Japan has hurt the company's earnings. After closing the Japanese production line, Panasonic will continue to manufacture TVs in Malaysia and the Czech Republic. At the same time, Panasonic is also considering outsourcing the production of small and medium-sized TVs to its Chinese competitor TCL. In the future, the Tokyo factory will be used for TV R&D and parts manufacturing. Panasonic has been producing home TVs since 1952, when the company's name was "Matsushita Electric Industrial Co., Ltd.". Panasonic TV’s global sales reached its highest value in fiscal [...]

Samsung may launch 5nm Exynos chipsets integrated with AMD GPUs in the second half of 2021

To compete with Apple's M1, Samsung will launch a new 5N Mexynos chipset with AMD GPUs in the second half of 2021. Even with reports that Qualcomm is working on the SC8280, Samsung clearly doesn't want to be left behind. "If all goes well, we may see new Exynos chipsets in our laptop or smartphone product lines," the source said The new Exynos chipsets are powered by a 5nm advanced manufacturing process that offers exceptional computing power, energy efficiency and battery life, making them useful for both laptops and smartphones. Although the source could not disclose further details about the new Exynos chipset, Samsung is likely to release a derivative version for the smartphone platform in June. Apple already has the M1 chip in its MacBook, MacMini, iPadPro and iMac all-in-one. Samsung is rumored to be working on a rival to Apple's A14Bionic chipset, but is currently hampered by poor [...]

Apple added $45 million in advanced manufacturing funds to its glass supplier Corning

Apple today announced an additional $45 million from the Advanced Manufacturing Fund to Corning, its longtime supplier of iPhone, iPad and Apple Watch glass, on top of $200 million in 2017 and $250 million in 2019. The total investment of $495 million will support Corning's continued research and development of "state of the art glass processes," which led to the creation of Ceramic Shield, a new material that is stronger than any smartphone glass. "Apple and Corning have a long history of working together to do the impossible," said Jeff Williams, Apple's chief operating officer. From the earliest iPhone glass to the revolutionary Ceramic Shield for the iPhone 12 series, our collaboration has changed the landscape for smartphone casing design and durability. The Ceramic Shield is a prime example of what is possible when deep innovation meets the power of American manufacturing. "We are proud to work with Corning, whose [...]

Fungi abound on Mars? Experts disagree

A group of scientists said that there are signs of life on Mars, images show that there are fungus like specimens similar to marblella, which seem to be emerging from the Martian soil, and its size is growing. However, some researchers said that the evidence is only speculative and far from enough to support the above conclusion. Experts say there are signs of fungus According to the report, 11 researchers from different countries and institutions said in a paper agreed to be published in the journal progress in microbiology that the analysis of images taken by some previous Mars exploration missions showed that "in a crack on the surface of Mars, there are white specimens with no fixed shape constantly changing their shape and position, and then disappeared within three days.". There are also signs that thousands of black, spider like materials will grow on a large scale in spring [...]

Parker Solar Probe intercepts radio signals from Venus' atmosphere

NASA's Parker Solar Probe has intercepted a set of radio signals from the atmosphere of Venus. NASA says studying the electrical radiation signals will help scientists understand how the planet's atmosphere is changing. Since its launch, the Parker Solar Probe has completed several recent flybys. During its last flyby of Venus' orbit, the Parker Solar Probe came within 833 km of Venus' surface at its closest point and sent back new images of the planet, the source said. Scientists believe the Parker Solar Probe is likely to pass through Venus's upper atmosphere, picking up a set of low-frequency radio signals from the planet's atmosphere in the process. NASA astronomers believe the radio signals are naturally occurring in their shape and strength, possibly coming from the ionosphere of Venus's atmosphere. According to the analysis, planets with atmospheres in the solar system usually have an ionosphere around them, which can bounce off [...]
