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…
In the field of switching power supply circuit board cloning from active shunt regulators and dummy loads from AC to low-voltage DC, flyback is the most popular topology at present, so engineer can choose to apply for switch power board reverse engineering to extract original layout diagram and gerber file, then redesign power tuning module…
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…
The ferrite magnetic amplifier in the Flyback Power Supply Circuit Board Gerber File Cloning is for dual output flyback power supplies that both provide actual power at both output ends (5V 2A and 12V 3A), both of which can achieve ±5% adjustment. When the voltage reaches 12V, it will enter a zero-load state and can’t…
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!…
The impedance value of a trace generated from Mul-tilayer PCB Circuit Board Gerber File Cloning generally depends on its line width and the distance between the trace and the reference plane. The wider the trace, the lower its impedance. In some interface terminals or pads of devices, the principle is also applicable. When the pad…
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…
The impedance value of a trace generally depends on its line width and the distance between the trace and the reference plane, and impedance is more likely to generated in the High Density Interconnect PCB board layout, engineer must pay special attention when Clone HDI PCB board to avoid discoutinuous impedance issue. The wider the…
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…
In the original electronic printed circuit board especially when re-routing multi-layer PCB board layout design, the hot spot must be avoid since signal vias will generate voids on the power layer and bottom layer. Therefore, unreasonable placement of vias is likely to increase the current density in certain areas of the printed circuit board power…
