Schematic diagram of the anti-push methods and practical tips 【thrust reversers schematic]
Update date：2012-7-5
Backstepping PCB schematic is also known as PCB files back to the schematic or the reverse principle of diagram design, it refers to the backstepping schematic PCB files or based directly on the PCB board in kind to depict schematic.
Why do we need backstepping schematic diagram, schematic diagram of what? The Backstepping map can help R & D personnel to understand the ideas and techniques of product development, secondary development in other people's product base above, and schematics to repair and provide great support and help.
Schematic diagram of great help in the commissioning and maintenance, such as your debugging encountered a chip is a code, the market can not buy, you need the schematic to confirm the model of the chip, the repair time is more important , with the schematic can greatly improve the efficiency of maintenance.
Shenzhen East guide backstepping PCB schematic technical team has extensive experience in its new reverse design ideas and methods and techniques, board-level power integrity analysis, the results of verification, and technical documents can be exported Reverse design away line is clear, rational layout and schematic, the backstepping schematic is too much.
In order to let more people the Backstepping map, do microblogging contribution for the development of Chinese science and technology, the following share practical tips backstepping schematic. Backstepping figure should be based on-chip signal might provide some clues, that is, to identify the use of the chip, and then find the chip-chip data, the Internet can search, usually make a backup copy, download chip data, a simple finishing, such as in accordance with the chip uses or preceded by the first letter of a simple classification. The next step is to meet the experience, marked the pin signal names according to the signal flow, the functional sub-regional, do not abuse the BUS, or throughout the marked network name net1, net2, etc. to express the connection relationship.
East guide technology consistently and resolutely resist the principle of drawing the graph into connected phenomena. Not only that, we attach great importance SCH Part package pin and physical pin corresponding relationship, focusing on the accuracy of transistor P / N polarity and the EBC by analysis of the optimization layer by layer, to adapt to the conventional design thinking and visual habits, readability very customer feedback is excellent.
Division I backstepping schematic and PCB are made strictly proofreading the network, component location diagram number, model, network names, and so complete and clear and easy to check all the components are endowed component values, readability and design Figure comparable. The backstepping schematic boards of mobile phones, computer motherboards, 10 laminates, high-frequency board. Backstepping Figure work can also be based on a different file such as gerber files, CAD files,
