5G is about to be commercialized. In some cities, the three major operators have started to lay out 5G on a large scale. In 12 pilot cities like Beijing and zhengzhou, 5G can be fully covered in urban areas as soon as the second half of this year. To achieve 5G technology, the use of [...]
In the world of modern electronic products, PCB(printed circuit board) is an important part of electronic products, it is hard to imagine that there is no use of PCB in an electronic equipment, so how the quality of PCB will have a very big impact on the long-term normal and reliable work of electronic products. [...]
At present, electronic devices used in various electronic devices and systems are still mainly assembled by printed circuit boards. Practice has proved that even if the circuit schematic design is correct and the printed circuit board design is improper, it will have a negative impact on the reliability of electronic equipment. For example, if two [...]
Preliminary circuit board Questions 1; What is printed circuit board? A conductive copper foil is printed on a plastic sheet, replacing the wires with copper foil, which connects the various components to form a circuit as long as they are mounted on the printed circuit board. Question 2; What is a PCBA? : The difference [...]
Entering 2019, the news of 5G will be endless, either the operators start large-scale testing, or terminal manufacturers release 5G phones. Recently, South Korea officially launched 5G services for the public, but also announced the opening of 5G commercial curtain. The commercial use of 5G will bring unlimited market opportunities to the upstream and downstream [...]

With the rapid development of electronic technology, the application of embedded system is more and more extensive. In many applications, people no longer consider the function and performance, but reliability and compatibility. Print circuit board (PCB) is the basic support of circuit components and devices in electronic products. The design quality often directly affects the [...]
1. New energy vehicles and autonomous driving will enhance the value of PCB In recent years, the trend of automobile electrification and electronicalization is more and more obvious. As the backbone of electronic products, PCB manufacturing is increasingly important in automobile supply chain. Compared with traditional fuel vehicles, new energy vehicles add charging, energy storage, [...]
On the net many about the hardware circuit experience, the knowledge lets the human dazzle. Things like signal integrity, EMI, and PS are designed to confuse you. Take your time, everything. I would like to discuss with you some of their own about the hardware circuit design experience, to "throw diversion jade", dedicated to those [...]
Let's first introduce the common drilling holes in PCB: through hole, blind hole and buried hole. The meaning and characteristics of these three kinds of holes. Through hole (VIA), a common hole used to conduct or connect copper foil lines between conductive patterns in different layers of a circuit board. Such as (e.g., blind hole, [...]
