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 [...]
PCB is the necessary circuit carrier of all electronic products and an important basic component in the electronic industry. To a certain extent, the development level of PCB industry reflects the development speed and technical level of a country or region's electronic information industry. Steady development of global PCB market scale With the development of [...]
At the same time, China's server usage is increasing year by year, accounting for about 27.2% of the world's in the first quarter of 2021. The main reason is still the promotion of domestic policies and the cooperation of domestic Internet companies. In addition to the deployment of super large data centers and the adoption [...]
Stimulated by the difficulties in arranging orders in the supply chain caused by the epidemic in 2020 and the acceleration of the pace of shangyun, the number of orders received by ODM operators is increasing quarter by quarter. Taking the L6 semi-finished products of ODM in the first quarter of 2021 as an example, the [...]
At first glance, PCBs are almost the same on the surface, regardless of their internal quality. It is through the surface that we see the differences that are crucial to the durability and function of the PCB throughout its life. Whether it is in the manufacturing and assembly process or in actual use, PCB should [...]
In PCB layout design, the most common technology is the circuit board grounding, from the most common single analog circuit loop grounding, simple digital circuit loop grounding to analog digital circuit hybrid grounding, from these grounding methods all show the development of electronic design. If the product you design has other requirements, for example, after [...]
