Reverse PCB schematic diagram

 

In the research of PCB reverse technology, the reverse diagram refers to the reverse diagram of the PCB based on the PCB File diagram or the reverse diagram of the PCB based on the actual product. It aims to describe the principle and working conditions of the PCB. The circuit diagram is also used to analyze the features of the product. In the forward design, the general product R & D should first carry out the schematic design, and then carry out the PCB design according to the schematic diagram.

PCB reverse diagram process:
1. Analyze the PCB layout and divide the circuit into several units;
2. Prepare two computers, view the PCB documents, and draw a schematic diagram;
3. retrieve all the components in the unit circuit and layout them with experience;
4. display the high brightness of a network in the PCB document and connect the electrical connection to another computer. After the entire network is connected, delete the network in the PCB document;
5. Repeat the above two items until all the networks in the PCB document are deleted, and then optimize the schematic.
PCB generation process:
1. design schematic in OrCAD
2. The process of generating the PCB reverse diagram in PowerPCB:
Whether it is used for analyzing circuit board principles and product operating characteristics in reverse research, or re-used as the basis and basis for PCB design in forward design, PCB schematics have a special role. In addition, it plays an indispensable role in product debugging, maintenance and improvement. Reverse schematic creation is the subdivision of our PCB Board copying service project.
We have Novel Reverse design ideas and techniques. We can conduct board-level power supply integrity analysis, verify the results, and reverse design the principle diagram with clear and reasonable layout based on the exported technical documents. Our reverse schematic diagram has been rigorously tested with the PCB. The component Position, model, and network name in the diagram are complete and clear and easy to query, the "modular" Rendering Method of "relatively concentrated functional module-related components" is adopted, and its readability is comparable to that of the original design image. Customers can easily grasp the design ideas of this product, capture the highlights of some high-end designs, and use them for their own purposes. They can also easily integrate their own unique designs to develop higher-end products.
The reverse PUSH Service of Shenzhen century core principle diagram starts with the chip signal as the clue, that is, the chip usage is first identified, and the pin signal name is marked based on the signal process based on the experience, and the function is divided into regions, never abuse the BUS or mark network names net1, net2, and so on to express the connection relationship. We pay great attention to the correspondence between the SCH Part packaging pin and the physical pin, pay attention to the accuracy of the P/N polarity of the transistor and EBC, and analyze layer-by-layer optimization one by one to adapt to conventional design ideas and visual habits, highly readable.
We have not only adopted the latest PCB reverse schematic software, but also accumulated rich experience and mastered hundreds of reverse push methods in years of practice. Professional to provide a variety of high frequency board reversed diagram and modification, multilayer blind buried orifice diagram Reverse Design, mobile phone board reversed diagram, 8-layer server computer motherboard schematic reverse design, A back-drawing schematic of PCB files with more than 10 layers provides detailed and accurate technical principles for your product R & D and design, final debugging, and post-maintenance.

PCBSchematic Creation

P. In Years of reverse R & D and independent PCB design, century core has a thorough understanding of the circuit principles and functional module features of various electronic products, A complete circuit schematic can be created based on the customer's product scheme, and the accuracy, efficiency and reliability of the PCB schematic can be fully ensured, helping shorten the R & D cycle in the customer's independent product R & D design, reduce R & D costs and quickly grasp the market opportunity window to promote the launch of new products.
At present, the typical schematic diagram is: Mobile Phone PCB schematic, MP3PCB schematic, MP4PCB schematic, digital camera PCB schematic, industrial control motherboard schematic, laptop motherboard circuit schematic, Power Charger circuit schematic, and so on.
