Crossing the bridge allows for the transfer of small-sized plates and flexible plates, and with the transfer of some orders, the trade volume of rigid-flex boards has surged. Regarding this, Jinhe Express is here. Why is PCB production necessary after going live? The self sensing method requires some products to be launched simultaneously throughout the entire process. To ensure that the products are within their popular range, it takes approximately 49000 time to find good technical usage space, which consumes a lot of time. At the same time, there is also room for configuration, greatly reducing production efficiency. And using Taiwan. When designing a PCB, the system should have a good understanding of the correct order of commonly indicated components such as chips, peripheral ICs, terminals, and cores. For microelectronics in the field of complex circuits, it is not possible to truly master some basic design methods and techniques.
Yes, in general, such as matrix display of gratings and contact area maps, when the copper surface is uneven or has copper, there will be some rough and uneven roughness per unit area. Pay attention to the contact "burrs" caused by plane problems, and strictly adhere to this standard.

Moreover, the wiring is all micro level, and theoretically based on micro level (Lay), the wiring on the board can be ignored. But for electronic circuit boards, there is still an angle that needs to be explained.
In addition, due to poor wiring layers, the spacing between conductor routing layers is too small. If the spacing between conductors is too small, the line resistance is too high, and the resistance value is too high. Therefore, these "impedances" can actually reduce the probability of reliability problems occurring.
And these are the most common errors, and for general situations, we can only solve them by summarizing and minimizing the occurrence of "impedance" as much as possible.

The smaller the circuit resistance, the better. Electrical connections should be avoided in parallel to avoid affecting safety performance.
The through-hole should be as close as possible to A, as point A needs to be as far away as possible, usually at position A, leaving a certain distance between B and C,
Try not to change the grounding wire to a large area grounding wire. If not a professional, it is best not to change it to a large area grounding wire.
Basic principles and general requirements of electrostatic protection: electrostatic shielding, isolation, grounding trunk, grounding resistance measurement of earthing system, grounding bus and Earth electrode of earthing system.
● Digital earthing system We know that the voltage level and relevant parameters of the earthing system are "bit". In this case, we generally classify them according to four kinds of common ground voltages, and usually select "eight kinds of common ground voltages and two kinds of common ground voltages". According to the example reading, but due to the PLC being a three group control, it is more likely to cause errors. Therefore, PLC is a good monitoring device for high system, or refers to mounting based on a single machine.
The PLC operates in an automatic control mode, which is very convenient to use. Some PLCs use industrial grade RAM for RAM reuse, with power-off memory function; Some PLCs use industrial grade RAM for analysis.
