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 Reverse Engineering Circuit Board Gerber File, you need to use a relatively small power resistor as a sampling resistor to sample large currents. Many times we will use a large package power resistor to do it, such as 2010, 1812, the power is generally 0.5W. But have we thought about using PCB traces to…
The component placement stage of the PCB Board Layout Reverse Engineering process is both science and art, requiring strategic consideration of the main components available on the circuit board. Although this process can be challenging, the way you place your electronic components will determine how easy your circuit board is to be reverse engineering and…
Reverse Engineering PCB Board Schematic Drawing which can be used to repair mal-functional electronic circuit board, schematic diagram itself must increase its maintainability, see below image: Increase the L1 inductance in the new PCB board schematic diagram after reverse engineering so that it can be disconnected during maintenance, making it easier to troubleshoot. Inductance, magnetic…
One of the purpose of PCB Board Reverse engineering is to restore its schematic diagram, how to draw a good Schematic Diagram of PCB Board Reverse Engineering is a main subject for the engineer, Not only the code is readable, but also the schematics. In many cases, the schematic diagram is not only for yourself,…
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…
