In the process of PCB copying board, the backstepping schematic refers to the PCB circuit diagram, which is directly released according to the PCB file diagram or directly according to the product substance. The purpose is to illustrate the principle and work of the circuit board. Also, the circuit diagram is used to analyze the functional features of the product itself. In the forward design, the general product development should be designed by principle diagram, and then the PCB is designed according to the schematic diagram.
The principle diagram of Shenzhen Kemaolong Electronic Technology Co., backstepping and PCB, which made the strict network map proofreading, component location, type, network name is complete and clear and easy to check, and the function modules of related components relatively concentrated "" modular "rendering, its readability and design can be comparable to the original. Customers can easily grasp the design concept of the product, capture some of the high-end design flash point, for their own use, but also easily integrate into their original design, develop a more high-end products.
We not only adopt the newest PCB reverse schematic software, but also have accumulated rich experience in many years' practice, and have mastered hundreds of backstepping methods. Provide all kinds of professional high-frequency board anti painted principle diagram and modified reverse design principle diagram of multilayer blind buried orifice, PCB mobile phone board copy board, principle of anti painted 8 tier server computer motherboard principle diagram of reverse design, 10 layer above the PCB file anti painted principle diagram and so on, and provide detailed and accurate technical reference for the product principle research and design of your final debugging and maintenance and maintenance.
Whether it is used to analyze circuit board principles and product work characteristics in a copy board, or to be used as the basis and basis for PCB design in forward design, the PCB schematic diagram has a special function. Moreover, plays an indispensable role in the product debugging, maintenance and improvement process, backward production is our principle PCB copy board services subdivision, you need to provide us with a model or PCB file, we can 100% accurate for you to derive the principle diagram of PCB model or PCB file.
Backstepping schematic technique:
First, the rational division of functional areas
In the reverse design of the schematic diagram of a well designed PCB circuit board, the rational division of functional areas can help engineers reduce unnecessary troubles and improve the efficiency of rendering. Generally speaking, the components with the same function on a PCB board will be centrally arranged, and the area divided by function can be conveniently and accurately based on the backstepping schematic.
However, the division of the functional areas is not arbitrary. It requires engineers to have a good understanding of electronic circuit knowledge. First of all, find out the core element of one of the functional units, then according to the line connecting the other components can be found with a functional unit will take, form a partition function. The formation of functional partitions is the basis of schematic drawing. In addition, don't forget to take advantage of the component numbers on the circuit board, which can help you perform functional zoning faster.
Two, find the benchmark
For engineers, the benchmark is not very complicated, in general, can choose to play a major role in the circuit components as a benchmark, they are generally larger and more convenient for the pin, drawing, such as integrated circuit, transformer, transistors and so on, can be used as a benchmark that fits this the reference element can also be said to be the main components of principle drawing at the beginning with, after determining the reference element, drawing according to these datum pins, to ensure the accuracy of the principle diagram to a greater extent.
Three. Draw wiring reasonably
For the ground wire, power line, signal line differentiation, also need engineers have relevant power knowledge, circuit connection knowledge, PCB wiring knowledge, and so on. These lines can be analyzed from the connection of components, the width of copper wires, and the characteristics of electronic products.
In order to avoid wiring drawing, line crossing and thrust, and can be used in large amounts of symbol grounding wire, different lines of various lines can use different colors to ensure clear, components can also use special signs of all kinds, can even separate unit circuit drawing, and finally combined.
Four. Master the basic framework
Some of the basic framework for electronic circuit structure and principle of drawing, engineers need to master, not only to the basic form of some simple and classic circuit for direct rendering, but also can form the overall framework of electronic circuit.
On the other hand, don't ignore the electronic products of the same type are similar in principle, engineers can according to the accumulation of experience, make full use of the similar circuit diagram for the product of the new principle of backstepping.
Five, check and optimize
After the completion of the schematic drawing, but also through the test and check links, we can say that the reverse design of the PCB schematic is finished. The nominal values of the components which are sensitive to the parameters of the PCB distribution need to be checked and optimized. According to the PCB file diagram, the schematic diagram is compared, analyzed and checked to ensure that the schematic diagram and the file diagram are in complete agreement.
If the layout of the schematic is found to be out of line with the requirements, the schematic diagram will be adjusted until it is fully reasonable and standard, accurate and clear
