5G commercial open, communication circuit board considerable flexibility

[5G commercially opened, communication circuit board is remarkably elastic] PCB circuit board is divided into seven categories by application: communication, computer, consumer electronics, industrial control medical, automotive electronics, aerospace and packaging substrate. Thanks to the construction of 3/4g communication network and the wide application of automotive electronics, the PCB output value in the communication and [...]

There are layering PCB design pay attention to? Good design can effectively control EMI

There are many ways to solve EMI problems. Modern EMI suppression methods include EMI suppression coating, EMI suppression parts and EMI simulation design, etc. Starting from the most basic PCB layout, this paper discusses the role and design skills of PCB layering and stacking in controlling EMI radiation. Power busbar The jump of IC output [...]

Environmental protection mechanical treatment method for circuit board recycling equipment

The environmental protection mechanical treatment method is to use the circuit board recycling equipment to deal with these waste circuit boards. The mechanical equipment solution method is to crush the waste circuit board into fine particles, and then realize the separation method according to the difference in physical properties, which generally includes crushing, grinding, sorting [...]

Electronic circuit board maintenance industry artifact, perforated electronic components of the — small tin furnace

I don't know if you have encountered the kind of copper foil particularly thick circuit board, soldering iron when the tin does not melt, the iron on the temperature of the moment to be scattered by the copper foil. Long time of heating can only leave a lump of small tin beads on the pin, [...]

How big is the hole, line width and line distance of electronic circuit board design?

For the setting of PCB wiring line width, two major issues should be considered: One is the amount of current flowing through it. For example, for the power line, we need to consider the current flowing through the circuit when it works. If the current flowing through is large, the line should not be too [...]

How to see the PCB anode and cathode

How to see the PCB anode and cathode 1. Large-area copper foil line is ground wire. The ground copper foil is usually thicker than the normal wire, and is connected everywhere on the circuit board. 2. The metal shell of components is ground wire. Some components have metal enclosures, such as switchgear, that enclose grounding [...]

PCB 3W rule and 20H rule and 50-5 rule analysis

In order to reduce crosstalk between lines, the spacing between lines should be large enough. When the spacing between the center of lines is not less than 3 times the width of lines, 70% of the electric fields will not interfere with each other, which is called the 3W rule. To achieve 98 percent of [...]

Master six skills of PCB layout design, making drawing easier!

Six things to consider when passing a PCB schematic to layout. All the examples mentioned were developed with the Multisim design environment, but the same concepts apply when using different EDA tools. Initial schematic transfer Device information, meshes, layout information, and initial wire-width Settings are also transferred during the transfer of the schematic to the [...]

What is particular about the layering of electronic circuit boards?

Decoupling must be handled in other ways, and we should choose a tight coupling between the signal and the current return plane. The advantages of a tight coupling between the signal layer and the current return plane outweigh the disadvantages of a slight loss of inter-layer capacitance. Therefore, the easiest way to improve the EMC [...]
