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,…
Because the Mosfet Drive Circuit Layout Design will have parasitic inductance, and the parasitic inductance and the junction capacitance of the Mosfet will form an LC oscillation circuit. If the output terminal of the driving chip is directly connected to the gate of the Mosfet tube, then on the rising and falling edges of the…
It is generally believed that MOSFET (MOS tube) is driven by voltage and does not require driving current. However, there is a junction capacitance between the G pole and the S pole of the Mosfet, and this capacitance will make it difficult to drive the MOS. The three capacitors in the figure below are the…
Reverse Design PCB Board Structure will be able to draws the PCB board spacial structure in the printed circuit board structural designing environment which is a critical part for reverse engineering circuit board, according to the determined circuit board size and various mechanical positioning on the printed circuit card surface, and place the required connectors,…
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…
Critical Signal in Electronic PC Board Cloning are playing important roles in the whole process of Printed Circuit Board EMC documents Reverse Engineering, 1. CS signal (sampling signal): pulled out from sampling resistors R25 and R26. Note that the ground wire of the IC is based on the sampling resistor, and the positive and negative…
Speaking of the difficulty of switching power supply PCB Board cloning, Clone Printed Circuit Board EMI Layout is not a big problem, but it must be one of the difficulties of switching power supply to layout a sophisticated PCB board (the PCB design is not good, which may lead to debugging parameters in how to…
When we talk about Low Frequency Analog Signal Package Grounding in the PCB board ground gerber file redrawing, let’s look at the size of the cross-talk in the case of the surface microstrip line. Assuming that the trace is controlled by 50Ω impedance, the line width is 6mil, the dielectric thickness is 3.6mil, and the…
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…
