PCB is an important electronic component, the support body of electronic components, and the carrier of electrical connection of electronic components. What are the requirements for PCB component layout? Let's introduce it to you. 1, the signal Signal interference is the most important factor to consider in PCB layout design. The most basic aspects are: [...]
Detailed knowledge of double sided circuit board welding. Compared with the single panel, the double-sided circuit board has higher wiring density and smaller aperture. The metallized holes on which interlayer interconnection depends are directly related to the reliability of printed circuit boards. With the narrowing of the aperture, some sundries, such as grinding debris, volcanic [...]
Limited and shrinking circuit board space, tight design cycles, and strict electromagnetic interference (EMI) specifications, such as CISPR 32 and CISPR 25, make it difficult to obtain a power source with high efficiency and good thermal performance. Throughout the design cycle, the power design is usually at the end of the design process, and the [...]
The new crown pneumonia epidemic has shrunk Thailand's printed circuit board exports by more than 21% in 2020, but will return to the growth trajectory with the 5G wave and changes in consumer behavior next year. In 2020, the global printed circuit board (PBC) business will be affected by the global pandemic of New Coronary [...]
Why is the color of the circuit board different? How many colors does the circuit board have? At present, the PCB circuit boards in the market are more common in green, black, blue, yellow, purple, red and brown; recently, PCBs of different colors such as white and pink have appeared. So, why do PCB circuit [...]
The circuit is very important in life now. There are various professional electrical equipment in the circuit. The safety of the electrical equipment in the circuit is also very important. This also makes us pay more attention to the selection of related equipment, thereby ensuring the electrical appliances in the circuit The operation is more [...]
Regarding the circuit board, I believe many friends are no strangers, and even some people will need to further process and manufacture the circuit board for a long time because of work. So what knowledge should we know about the circuit board? There are many types, and there is also a lot of professional knowledge. [...]
When it comes to circuit board design, obviously this is a professional issue. In view of the current market environment and technical requirements, in the process of circuit board design, it is natural to pay attention to and in-depth thinking and preparation of some detailed issues In general, if you want to design a type [...]
Why does the LED lamp with a few watts of power have a very high temperature in the housing? This is because the efficiency of converting electrical energy into light energy is not high, and a large part of electrical energy is converted into heat energy. The efficiency of converting the electrical energy consumed by [...]
Recently, the team of Fu Qiang, a researcher from the State Key Laboratory of Catalysis, Dalian Institute of Chemical Physics, Chinese Academy of Sciences, and TSMC ’s Lain-JongLi team, Taiwan Jiaotong University ’s Wen-Hao Chang team, Rice University ’s BIYakobson team, and Peking University ’s professor Zhang Yanfeng Teamwork, successfully epitaxially grown a single-crystal hexagonal [...]
