FPC, also known as flexible printed circuit board, is a printed circuit made of flexible insulating substrates (polyester film or polyimide). It has many advantages that printed circuit boards do not have. FPC flexible circuit boards can not only bend freely, but also Folding and winding, it also has the characteristics of light weight, small [...]
Classification of road boards According to the number of layers, there are three types of single-sided, double-sided, and multilayer circuit boards, according to the circuit layers inside. The first is a single-sided circuit board. On a general circuit board, the components are on one side of the board, and the circuit is on the other [...]
High-frequency circuit board design is a very complicated design process, and its wiring is essential to the entire design! With the continuous development and progress of electronic technology, large-scale high-precision PCB circuit boards have been widely used, components in printed circuits The mounting density on the board is getting higher and higher. Simple single-sided and [...]
Conformal coatings are used to enhance the performance and reliability of printed circuit board assembly, enabling it to be used in harsh environments such as underwater, aerospace, and military applications. Consumer electronics manufacturers are increasingly using conformal coatings as an economical method to improve product reliability. When a printed circuit assembly board without a conformal [...]
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 [...]
