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.
Printed Circuit Board component library Reverse Engineering need to prepare component list and netlist, functional blocks and other important elements; The preliminary preparation includes preparing component libraries and schematic diagrams In order to manufacturing a well-functional PCB board, in addition to designing the printed circuit board principles, it is also necessary to redraw electronic pcb…
PCB Board Reverse Engineering often use protective ground wires for isolation to suppress mutual interference between signals. Indeed, the protective ground wire can sometimes improve the isolation between signals, but the protective ground wire is not always effective, and sometimes even worsens the interference. The use of the protective ground wire must be carefully analyzed…
Reverse Engineer Power Board to avoid over-current is an proved effective method, use existing arc suppression circuits to provide over-current protection and consider 5V 2A and 12V 3A flyback power supplies circuit board gerber file design. One of the key specifications of the power supply is to provide over power protection (OPP) for the 5V…
Reverse Engineering Power Supply PC Board can help engineer to extract layout drawing, gerber file, BOM List and schematic diagram from original Power supply printed circuit board, the procedures as below: First: Accept the power supply PC board layout redesign requirements! Evaluate the cost and make a feasible plan. Secondly: According to the customer’s quotation!…
If the distance between high-speed signal lines is too close in the original printed circuit board layout diagram and gerber file, it is easy to produce crosstalk, so it is necessary to reverse engineering printed circuit board original layout diagram, gerber file, Sometimes, due to circuit board layout, board frame size and other reasons, the distance…
Reverse Engineering High Speed PCB Board Signal Line must take the bending method of trace into consideration, the bending method of the trace must follow the relayout printed circuit board gerber file rule, avoid bending the signal lines as much as possible. If you have to bend the trace, do not trace it at an acute…
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…
