PCB Reverse Engineering technology is used to reversely analyze the printed circuit board, and to acquire the Layout Drawing, Gerber File, Bill of materials (BOM), Schematic diagram and designators drawing are restored in the aspect ratio of 1:1, and then these technical documents and production files are used for PCB board remanufacturing, component soldering, flying probe testing, circuit board debugging, and complete replication of the original circuit board.
When we Reverse Engineering Power Supply PCB Board, the Digital circuits often require discontinuous currents, so inrush currents are generated especially for some high-speed circuit board reverse engineering. If the power trace is very long, the presence of inrush current will cause high-frequency noise, and this high-frequency noise from Power supply PCB Board will be…
Reverse Engineering Circuit Board Schematic Diagram needs to identify the PCB board’s circuit pattern dissipation and layout PCB circuit pattern logically: For distinguish of ground plane, power supply circuit and signal circuit, also require engineer to have related power supply, circuit connection, PCB board layout and PCB layout reverse engineering rules. How to distinguish these…
PCB Board Schematic Diagram Recovery is a process to extract schematic diagram from existing printed circuit board, this is a part of the PCB reverse engineering service, we should firstly carve out different zones according to functions, carve up different zones according to module function can greatly help engineers to avoid some unnecessary troubles, improve…
For High Speed Digital Signal PCB Board Reverse Engineering, a 90° corner will have a certain impact on high-speed signal transmission lines. For our current high-density high-speed PCBs, the general trace width is 4-5mil, and the capacitance of a 90° corner is about 10F. It is estimated that the cumulative delay caused by this capacitance…
Reverse Engineering High Speed Circuit Board Schematic Diagram to avoid circuitry pattern layout at 90° corners, High-frequency and high-speed signal transmission lines should avoid routing at 90° corners, which is strongly required in various PCB Design Guides and rule checking. Because when clone high-frequency and high-speed signal transmission PCB board lines need to maintain the same…
Reverse Engineering A PCB Board to Avoid Sharp Angle is a subject to discuss when we are thinking about How to avoid sharp angles when relayout the circuitry diagram of PCB board, causing acid trap DFM problems? Modern EDA PCB design copying software (such as Cadence Allegro, Altium Designer, etc.) comes with complete layout routing…
Whether the PCB can be traced at an acute angle, the answer is no, as a result of that, the requirement for Reverse Engineer PCB Board With Acute Angle is existed. Regardless of whether the trace at an acute angle will have a negative impact on the high-speed signal transmission line, from the aspect of…
In the consideration of Reverse Engineering PCB Board EMC Design, the first thing involved is the setting of layers; the number of layers of the printed circuit board is composed of the number of power, ground and signal layers; In the EMC design reverse engineering of printed wiring board, in addition to the selection of…
To figure out how to increase the over-current capability of the PCB circuit board, Reverse Engineering PCB Board Layout Circuitry scheme will do. Take a double-layer PCB board reverse engineering as an example. This kind of circuit board usually has a three-layer structure: copper foil, substrate plate, and copper foil. The copper foil is the…
In the process of DDR Memory Circuit Board Layout Design, the signals DQ, DM, and DQS are all point-to-point interconnections, so no topology is required for printed circuit board cloning. However, the exception is that this is not the case in the reverse engineering of multi-rank DIMMs (Dual In Line Memory Modules) design. In the…
