Current density of wiring : Most electronic circuits are now made of copper-bonded insulating boards. The copper thickness of commonly used circuit boards is 35μm. The current density value of the wiring can be taken according to the empirical value of 1A/mm. The specific calculation can be referred to the textbook. In order to ensure…
1.Definition of ground What is ground? The definition of ground that everyone learns in textbooks is: ground is an equipotential body that serves as the potential reference point of the circuit. This definition does not conform to the actual situation. The potential on the actual ground is not constant. If you use an instrument to…
With the improvement of power semiconductor device performance and the innovation of switching conversion technology, power electronics technology has been widely used in various power supply equipment. At present, switching power supply products are becoming more and more small, high-speed and high-density. This trend has led to increasingly serious electromagnetic compatibility issues. The high-frequency switching…
Today, PCB design considers more and more complex factors, such as clock, crosstalk, impedance, detection, manufacturing process, etc., which often requires designers to repeat a lot of layout, routing, verification and maintenance work. The parameter constraint editor can compile these parameters into formulas to help designers better handle these sometimes even conflicting parameters during the…
1.Q: We have introduced the problem of pure resistance. There must be some resistors whose performance is exactly what we expected. What about the resistance of a wire? A: It is different. You probably mean a wire or a conductive strip in a printed circuit board that acts as a wire. Since room temperature superconductors…
In today’s wireless devices, more than half of the components on the circuit board are analog RF devices, so an effective way to reduce circuit board area and power consumption is to carry out larger-scale RF integration and move towards system-level chip. This article introduces the current status of RF integration and proposes countermeasures and…
In high-speed design, the characteristic impedance problem of controlled impedance boards and lines troubles many Chinese engineers. This article introduces the basic properties, calculation and measurement methods of characteristic impedance in a simple and intuitive way. In high-speed design, the characteristic impedance of controlled impedance boards and lines is one of the most important and…

To repair a relatively unfamiliar circuit board without any schematic diagram, the so-called “experience” in the past will be difficult to achieve. Although people with a solid hardware foundation are confident in repair, if the method is not appropriate, the work will still be ineffective. So, how can we improve the efficiency of repair? According…
