The conventional wire harness is made of copper wire surrounded by plastic, and several strands of wire are wrapped into an insulator to form a wire harness. When the battery pack is connected, each wire harness must reach an electrode. When there are many current signals in the power battery pack, a lot of wiring [...]
In some cities, the three major operators have begun to deploy 5G on a large scale. To achieve 5G technology, it is inseparable from the use of circuit boards. In the electronics industry, flexible circuit boards can be said to be the vasculature of electronic products. Especially in the trend of thin, thin, miniaturized, wearable, [...]
1. The current development status of PCB The main function of PCB is to connect various electronic components to the preset circuit, which plays the role of relay transmission. PCB is a key electronic interconnection component of electronic products, a support body of electronic components and a carrier of electrical connection. The global PCB market [...]
Generally speaking, whether it is a passive crystal oscillator or an active crystal oscillator, the distance between it and the chip needs to be as short as possible. The clock signal source is usually the most serious EMI (Electromagnetic Interference) radiation source in the system. If you connect a long wire, it is easy to [...]
After the inverter has not been started for a long time, when it is started again, many users respond that the main board or the explosion module will be burned when the inverter is powered on. In this regard, we will analyze the possible causes of this situation in inverter maintenance 1. Due to the [...]
In some production and processing links of electronic processing plants such as SMT patch processing, testing, transportation, etc., it will inevitably produce certain mechanical stress on the circuit board, and if this force exceeds the limit that the circuit board can withstand, it is very There may be some adverse effects on electronic components, such [...]
There are many components on the circuit board. Their functions are different and have their own functions. They can complement each other to make the electronic product work normally or for a long time; let us talk about the role of the diode in it. The current flowing through the inductor coil in the circuit [...]
On May 19, 2020, in Munich, Germany and Boca Raton, Florida (GLOBE NEWSWIRE), HENSOLDT, a sensor solution provider, and Nano Dimension, a leading supplier of 3D printed electronics (AME)/printed electronics (PE), are using 3D Significant breakthroughs have been made in the development of high-performance electronic components in printing technology. Using Nano Dimension’s newly developed dielectric [...]
The circuit connection of the multi-layer board is through the buried hole and blind hole technology. Most motherboards and display cards use 4-layer PCB boards, and some use 6, 8-layer or even 10-layer PCB boards. To see how many layers there are on the PCB, it can be identified by observing the via holes, because [...]
FPC is a kind of printed circuit board, which is called flexible circuit board, and we call it FPC soft board. FPC generally uses PI as the base material, which can be bent and flexed arbitrarily. PCB is a so-called rigid circuit board, which is usually called a hard board. PCB generally uses FR4 as [...]
