I. definition of inductance Inductance: a physical quantity used to measure the electromagnetic induction capacity of a coil. When a current is fed into a coil, a magnetic field is generated around the coil, and the coil has a magnetic flux passing through it. The greater the power supply through the coil, the stronger the [...]
Integrated circuit in all kinds of circuits are used, integrated circuit pin density, not easy to disassemble welding, as a general maintenance master or electronic technology practitioners, how to welding integrated circuit, and we talk about the following. Method/procedure 1. Dual in-line integrated circuit, two soldering irons can be used, and tin can be added [...]
The advantage of the innocuous treatment technology of the circuit board recycling equipment is that the epoxy resin is recovered, which not only avoids the pollution caused by the burning of organic matter, but also comprehensively recovers the epoxy resin. Circuit boards are the basic materials of electronic appliances, and China has become a major [...]
Circuit board manufacturing belongs to modern electronic industry. Circuit board also known as: PCB board, aluminum substrate, high frequency board, PCB board, PCB, circuit board, printed circuit board, kunshan circuit board, kunshan circuit board, flexible board, flexible board and so on. Circuit board also known as: PCB board, aluminum substrate, high frequency board, PCB board, [...]
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 [...]
