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.
The first step of Copy Printed Circuit Board Gerber File is to get a PCB. Record the model, parameters, and position of all the components on the paper, especially the direction of the diode, the three tubes, and the direction of the IC notch. It is best to take a photo of two positions with…
Even if the wiring pattern and layout drawing in the entire PCB board Gerber file is completed well, the interference caused by the inconsistency of the power supply and the ground line may degrade the performance of the product, and sometimes even affect the success rate of the product. Therefore, the Circuitry Pattern of electricity…
In the PCB Board Cloning, circuitry layout is an important step to complete the product design. It can be said that the previous preparation work is done for it. In the whole PCB, the circuitry layout process is the highest, the trick is the finest, and the workload is the largest. The PCB board cloning…
The lead wire of the circuit board and the electronic component has parasitic impedance, as a result of that, extra attention must be paid onto it when Reverse Engineering Electronic PCB Board Lead Wire, also it cannot ignore its influence in the high frequency field like the floating capacity. The parasitic impedance of the wire…
In the process of High Frequency PCB Circuit Card Reverse Engineering, the index is usually recorded in the engineer’s catalogue in the form of self-resonance frequency. If the frequency below self-resonance is used directly, the reactance will become positive, mainly because the reactance is the same as the impedance, if the frequency is more than…
When Reverse Engineering Analog Digital Hybrid Circuit Board, it must be noted that the digital circuit switching will generate a transition current. Since the transition current will flow into the ground of the reset circuit, in order to prevent the current from flowing into the ground of the analog circuit, the ground of the analog…
Reverse Engineering PCB Board Analog Circuitry requires attention. In addition, there are still design elements that cannot be described on the layout drawing and schematic diagram. The circuit characteristics are changed in the form of wires, floating capacity, etc. In order to ensure the reliability of the PCB Board, these designs must be The elements…
Due to the high speed of the IC and the LSI semiconductor itself, and in order to achieve the purpose of normal operation of the High Density Printed Circuit Board Design, the technical competition is becoming more and more fierce and it is also become more important for the Integration of Analog & Digital Technology.…
Generally, engineer must consider Clone Printed Circuit Board Conductor Lost Effect, since the substrate pattern cross-sectional area is 100 μm, the DC resistance is about 172 Ω/m, and the MCM pattern cross-sectional area using the miniaturized wire is about 30 μm, but the DC impedance is as high as 573 Ω/m, assuming that the impedance…
Mosfet component can shortens the circuitry delay on the board, which is the basic condition for cloning a high-speed transmission PCB board, and the shorter the length of the line, the better. Reducing the wire delay time usually adopts two methods: wire material length. The delay time per unit length is proportional to the square…
