EMI not only affects the normal operation of electronic device ,but also may have potential harm to human health.Therefore,EMI technology become the important research direction .This article will detailed introduce the theory material and application of…

1.Fault characteristics and repair of capacitor damage in industrial control circuit boards Faults caused by capacitor damage are the highest in electronic equipment, especially electrolytic capacitor damage is the most common. Capacitor damage is manifested as: Capacitance decreases; Complete loss of capacity; Leakage; Short circuit. Capacitors play different roles in circuits, and the faults they…

When designing a circuit, you usually need to lay out the board yourself. Many professional books have detailed introductions on how to use PCB design software, component packaging, distance and other parameters. Here I will summarize my personal experience. Some parts may be incorrect. Friends who know can give me some advice and learn together….

PCB (Printed Circuit Board), Chinese name is printed circuit board, also known as printed circuit board, printed circuit board, is an important electronic component, a support for electronic components, and a provider of electrical connections for electronic components. Because it is made by electronic printing, it is called a “printed” circuit board. There are two…

Packaging refers to connecting the circuit pins on the silicon chip to the external connector with wires so as to connect with other devices. The packaging form refers to the shell used to install the semiconductor integrated circuit chip. It not only plays the role of installing, fixing, sealing, protecting the chip and enhancing the…

Via is one of the important components of multi-layer PCB, and the cost of drilling usually accounts for 30% to 40% of the cost of PCB board manufacturing. Simply put, every hole on the PCB can be called a via. From the perspective of function, vias can be divided into two categories: one is used…

The heat generated by electronic equipment during operation causes the internal temperature of the equipment to rise rapidly. If the heat is not dissipated in time, the equipment will continue to heat up, the device will fail due to overheating, and the reliability of the electronic equipment will decrease. Therefore, it is very important to…

Wiring is an extremely important part of PCB design, which will directly affect the performance of the PCB board. In the PCB design process, different layout engineers have their own understanding of layout, but all layout engineers are consistent in how to improve the efficiency of wiring, which can not only save the development cycle…

1 Tinning effect When hot liquid solder dissolves and penetrates the metal surface to be soldered, it is called tinning of the metal or tinning of the metal. The molecules of the mixture of solder and copper form a new alloy that is partly copper and partly solder. This solvent effect is called tinning, which…

As an important part of PCB design, copper coating, whether it is domestic Qingyuefeng PCB design software or some foreign Protel and PowerPCB, all provide intelligent copper coating function. So how to coat copper well? The author of this article shares some of his ideas with you, hoping to benefit peers. The so-called copper coating…

PCB board design is a compulsory course for electronic engineers, and it is not as easy as it seems to design a perfect PCB board. A perfect PCB board not only needs to have reasonable component selection and setting, but also needs to have good signal conduction performance. This article will introduce and share the…

Power bus Reasonably placing capacitors of appropriate capacity near the power pins of IC can make the jump of IC output voltage faster. However, the problem does not end there. Due to the limited frequency response characteristics of capacitors, capacitors cannot generate the harmonic power required to drive IC output cleanly over the full frequency…

1.High heat generation devices plus heat sinks and heat conducting plates When there are a few devices on the PCB that generate a lot of heat (less than 3), a heat sink or heat pipe can be added to the heat generating device. When the temperature cannot be lowered, a heat sink with a fan…

At present, electronic equipment used in various electronic equipment and systems still uses printed circuit boards as the main assembly method. Practice has proved that even if the circuit schematic is designed correctly, improper design of the printed circuit board will have an adverse effect on the reliability of electronic equipment. For example, if two…
