PCB copy board in the process, is the inverse schematic diagram based PCB files directly from the anti- product launch or depict a real PCB schematics, circuit board designed to illustrate the principles and working conditions . Further, this circuit is also used to analyze the functional characteristics of the product itself . In the forward design, research and development of products to conduct general schematic design , PCB design and then according to the schematic .
Not only do we use the latest PCB reverse schematics software and years of practice , has accumulated a wealth of experience , proficiency in the hundreds of anti- push mode . Professional offers a variety of high-frequency board schematics and modifying anti- painted , multi- blind buried plate design schematics Reverse phone board PCB copy board , reverse painted schematics, 8 -tier server computer motherboard schematic reverse design , 10 floors above file Anti- painted PCB schematics , etc., to provide detailed and accurate technical principle reference for your product design and final commissioning and post- maintenance and repair.
Whether it is being used in the analysis of the circuit board copy board in principle and operating characteristics of the product , or be re- used in the forward design of the PCB design basis and foundation , PCB schematics have a special role. Moreover, the product plays in commissioning, maintenance and improvement process indispensable role , making the reverse schematics PCB copy board is a breakdown of our services , you can just give us a model , or PCB document , we can be 100 % accurate for you to derive the schematic model of this PCB or PCB files.
Inverse schematic technologies:
Reasonable division of a functional area
Against a well- designed PCB circuit board schematics reverse when reasonable division engineer functional areas can help reduce some unnecessary trouble and improve rendering efficiency. In general , a function of the same components on the PCB layout will focus on in order to function zoning can have easy and accurate at the time of the thrust reverser according to the schematic .
However, the division of the functional areas is not random. It requires knowledge of electronics engineers have a certain understanding . First, find a functional unit of the core components , and then connect the other components can follow it to find out the same functional unit according traces form a functional partition. Zoning is the basis for the formation of functional schematic drawing . In addition, in the process , do not forget the clever use of part numbers on the board, they can help you faster functional partition.
Second, find the reference member
For engineers, benchmarking piece is not very complex matter , under normal circumstances , you can choose to play a major role in the circuit components as a reference piece , they are generally larger, pin more convenient draw conducted such as integrated circuits , transformers, transistors , etc., can be used as an appropriate benchmark pieces
The reference member can be said that during the main part schematic drawing of the beginning of the means , after determining the reference member , the reference member according to the draw pin , to ensure the accuracy of the schematic in greater extent .
Third, reasonable layout drawing
For the ground , power lines, signal lines of distinction , also need power engineers have relevant knowledge , knowledge of the circuit connection , PCB layout knowledge and so on. The distinction between these lines can be analyzed from the connection part , the line width of the copper foil and electronic characteristics of the product itself, and so on.
Draw in the wiring , in order to avoid cross the line and interludes, heavy use of ground can be grounded symbols, various lines of different lines of different colors can be used to ensure legible , there are a variety of components can also use special signs , even the rendering unit circuit separately , and finally combined.
Fourth, to master the basic framework
For some basic electronic circuits and schematic drawing of the frame constituting method requires skilled engineers to use , not only to form the basic components of simple , classical circuit unit for direct rendering, but also the overall framework of the electronic circuit can be formed .
On the other hand , do not ignore the same types of electronic products have a certain similarity in the schematic, engineers can gain experience , to fully draw circuit diagrams similar to push new products anti schematic .
Fifth, check and optimization
After the schematic drawing is completed, tested and checked but also to say that the end part of the reverse design PCB schematic . The nominal value of the parameter for the distribution of sensitive components PCB needs to be checked optimization, according to PCB document map, the comparative analysis of the schematic and check to ensure that the file is fully consistent with the schematic diagram .
If it is found in the check in the schematic layout does not match with the requirements , will be adjusted to the schematic , until it reaches the completely rational and standardized , accurate and clear.
