With the rapid development of integrated circuit industry, the demand for PCB circuit board only increases, but the market demand is large. PCB is the so-called printed circuit board, which is the support of electronic components and the indispensable carrier of electronic printing. At the same time, there are many PCB circuit board manufacturers, so [...]
En el proceso de producción de PCB, hay dos tipos principales de equipos de galvanoplastia, uno es la línea de galvanoplastia horizontal, el otro es la línea de galvanoplastia vertical.Estos dos tipos de equipos de galvanoplastia de estructura diferente, principalmente el modo de transporte de la placa de circuito es diferente, la estructura del equipo [...]
Some Huawei mobile phones have started to push the upgrade of Hongmeng OS 2.0 system. According to @ Chang'an digital Jun, a microblog blogger, someone has already received a push from Huawei's harmony OS. According to different models, the size of the update packets received is also different. Some are 2.87 GB, while others are [...]
After a long silence, Intel finally updated its new 11 generation desktop core processor. On the 11th generation mobile terminal, Intel has introduced the iris Xe core graphics card for the processor, with "no plug-in performance" as the core selling point. However, the 11th generation core desktop terminal released yesterday only said nothing about "no [...]
April 27 news: Recently, MediaTek and Ericsson have successfully completed the 5g NR dual connection test, effectively combining the wide coverage of sub-6ghz band and the high-speed characteristics of millimeter wave (mmwave), using a variety of spectrum resources to provide higher network speed and lower delay. This move will be conducive to the promotion of [...]
Earlier this month, the semiconductor industry association of America (SIA) and Boston Consulting Group (BCG) jointly released a research report, through more than 20 charts, to analyze and present the distribution characteristics of global semiconductor supply chain in detail. The 53 page report "strengthening the global semiconductor supply chain in an era of uncertainty" mentioned [...]
Most modern PCs no longer have physical COM ports. However, many hardware settings still use UART for logging, diagnostics, and application control. The alternative is to use a USB device, which is displayed as a COM port on the PC. Virtual COM port (VCOM) is a technology used to replace the traditional COM port on [...]
In order to design a circuit, you must have the most basic knowledge of components and know the parameters and characteristics of components. Understand the components of various circuits; Familiar with analog circuit and digital circuit, and can program. It's best to start with making power supply first; Then learn more about modern high-tech products [...]
In essence, laser drilling is a kind of thermal processing method that focuses the laser beam on the workpiece and changes the light energy into heat energy. It is the action process of laser pulse radiation with certain energy density on the workpiece material. After focusing, the laser is used as a high-intensity heat source [...]
With the beginning of TSMC's price increase, the price increase due to lack of core has been accepted by major manufacturers in the semiconductor industry. The shortage of chips is not only the shortage of raw materials, but also the problem of production capacity. However, the research and development of new materials will improve the [...]
