Overview PCB copy board proofing and schematIC diagram
Preconditions of the printed circuit board, the copy of the printed circuit board, the proofing of the printed circuit board is to conduct the proofing of the physical objects of the electronic products and the printed circuit board before the corresponding operations This operation is a reverse operation The main purpose is to use the original file and bill of materials on the circuit board to print in 1:1 ratio After obtaining these electronic files, you can make corresponding plates
If you copy and proofread a PCB, the first step you need to perform is to unload various components, and then obtain a pure PCB. After scanning the circuit board, obtain the corresponding file information. In the scanning process, it must be mapped according to the corresponding position. After obtaining the file, solder the original widget, debug the circuit accordingly, and finally copy the complete circuit board.

In fact, there are many professional PCB copying companies that can not only complete the copying step, but also successfully complete the proofing of PCB for you. This is a high-tech activity. Many people have such a question, that is, what is the price of the copy board of PCB. In fact, it depends on the thickness, size, wiring density and total number of components of the board to be copied.
PCB copy is not imitation, but the most comprehensive recovery to every SMAll detail. Remember, as long as you have a sample of the circuit board, you can find a professional company to copy the circuit board for you. After the board copy is completed, the board can be developed and updated. I believe that your products can be updated under this technology. It can also give you a better choice.
The final result of PCB copy board proofing depends on your choice. When you choose a highly professional company, there will be no mistakes in the proofing process. It is important to know that there are many small parts on the circuit board. If one of the widgets has a vulnerability, the final result will be affected. Recall that, at any time, PCB copy boards need to have professional skills, and professional things are done by professionals.
PCB copying and proofreading are carried out without any electronic documents. The only resource you can use is the PCB sample In order to save the company's production costs and development costs All you can do is copy the blackboard with some kind of pipe With this pipeline, you can achieve the final goal and obtain the required production files And the cost is very low Recall that if a small company or individual wants to duplicate the board of directors, it is the best choice to find a professional company to do this

Schematic diagrams are often referred to as circuit diagrams. Circuit diagram is a figure drawn with agreed symbols, which is used to represent the circuit structure required by research and engineering. You can understand the actual circuit situation through the circuit diagram. circuit components are represented by general symbols in the drawing, and lines connecting symbols represent wires. Basic circuit diagrams are commonly used in engineering and building projects.
In PCB design process, understanding PCB design principles is the most basic process. PCB design is a scientific and technological activity. With PCB design principles, drawing area and working parameters as the basic requirements, mastering the placement methods and wiring sequence of various components can truly realize the reproduction of PCB.
At present, the power circuits of our electronic products mainly include linear power supply and high-frequency switching power supply. Theoretically, linear power supply means how much current most users need and how much current this input terminal must provide; Switching power supply means how much power most users need and how much power input terminals need to provide.
So, what are the features of the linear power supply? It is not difficult to find that the linear power supply is composed of functional components such as rectifier, filtering, voltage stability, and energy storage At the same time, the commonly used linear power supply is a series regulated power supply, and the output current is equal to the input current, that is, I1=I2+I3. I3 is the reference terminal, and the current is very small, so I1 – I3. We talk about the current because in PCB design, the width of each line is not randomly set, But is determined according to the current between the component nodes in the schematic (for details, see "PCB design copper platinum thickness", line width and current relationship table ")
