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.
“Noise problem!” – This is the problem that every PCB Board engineer will hear. In order to solve the noise problem, it often takes several hours to carry out laboratory tests in order to find out the culprit, but in the end, it is found that the noise is caused by improper PCB layout of…
Reverse Engineering Circuit Board to Reduce Noise & Electromagnetic Inteference can be carried out through below practical aspects: The printed circuit board is divided by frequency and current switching characteristics, and the noise component is farther away from the non-noise component. Single-panel and dual-panel single-point power supply and single-point grounding, power supply track, and grounding…
Since the sensitivity of electronic equipment is getting higher and higher, which requires the anti-interference ability of the equipment to become stronger and stronger, Therefore, Reverse Engineering PCB to Reduce Noice and Electromagnetic Inteference has become more difficult. How to improve the anti-interference ability of PCB has become one of the key issues that many…
PCB Reverse Engineering Impedance Matching is a suitable way to match a signal source or transmission line to a load. According to the access method, the impedance matching has two modes: serial and parallel. According to the frequency impedance matching of the signal source, it can be divided into low frequency and high frequency. 1st…
Today let’s talk about the difference between PCB Reverse Engineering and PCB Design, PCB Board design is just as the name suggests: design the circuit board as required. Circuit board reverse engineering is simply to customize the board according to the provided physical printed circuit board sample. The circuit board design is mainly because the…
It is a frequent need to have schematic diagram in the industry of PCB Board cloning, repairing and maitenance, especially for those expensive, rare to find or obselete which has already phased out for the production for many years without the possibility to buy the new one. Engineer will normally try to Restore Schematic from…
A good performance Printed circuit board, in addition to selecting high-quality components, reasonable circuitry design, the component layout of the printed circuit board and the correct structural design of the electrical wiring direction is a key issue that determines whether the Printed circuit board can work reliably. Through Reverse Engineering Printed Circuit Board Gerber File,…
Any trace on the Temperature Sensor PCB reverse engineering will cause a time delay to the signal when passing through a high-frequency signal. The main function of the serpentine trace is to compensate for the lesser delays in the “same group of related” signal lines. Usually there is no or less logic than other signals;…
There is usually no problem with the input source and output load current loops. The current waveforms in these loops are a superposition of large DC currents and small AC currents. Special filters are usually required in these two circuits to prevent AC noise from leaking into the surrounding environment. The input and output current…
In any Switching Power Supply PCB Board Cloning, the physical design of the PCB is the last link. If the cloning method is not correct, the PCB may radiate excessive electromagnetic interference, resulting in unstable power supply. As a designer, you must understand the physical workings of the circuit and design a high quality switching…
