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.
Microstrip Guideline by Vehicle Dynamic Module PCB Copying This example touches an interesting and quite handy point. Reference 17 discusses a useful guideline pertaining to microstrip impedance on Vehicle Dynamic Module PCB Copying. For a case of dielectric constant of 4.0 (FR-4), it turns out that when W/H is 2/1, the resulting impedance will be…
Microstrip Transmission Lines on Digital Racing Dash Display PCB Cloning For a simple two-sided Digital Racing Dash Display PCB Cloning where one side is a ground plane, a signal trace on the other side can be designed for controlled impedance. This geometry is known as a surface microstrip, or more simply, microstrip. A cross-sectional view…
Reverse Engineering PCB Board with Controlled Impedances Trace A variety of trace geometries are possible with controlled impedance designs from Reverse Engineering PCB Board, and they may be either integral to or allied to the PCB pattern. In the discussions below, the basic patterns follow those of the IPC, as described in standard 2141. Note…
Reverse Engineering PCB Thoughtfully Once the system’s critical paths and circuits have been identified, the next step in Reverse Engineering PCB is to partition the printed circuit board according to circuit function. This involves the appropriate use of power, ground, and signal planes. Good PCB layouts also isolate critical analog paths from sources of high…
Transmission Line in Power Module Circuit Card Cloning The benefits of outward and return signal paths being close together so that inductance is minimized. As shown previously in Figure 7-30, when an HF signal flows in a PC track running over a ground plane, the arrangement functions as a microstrip transmission line in Power Module Circuit…
Skin Effect on ECM PCB Copying At high frequencies, also consider Skin Effect on ECM PCB Copying, where inductive effects cause currents to flow only in the outer surface of conductors. Note that this is in contrast to the earlier discussions of this section on dc resistance of conductors. The skin effect has the consequence…
High Circuit Impedance on Circuit Attack Counter PCB Reverse Engineering Since low power circuits tend to use high value resistors to conserve power, this tends to make the High Circuit Impedance on Circuit Attack Counter PCB Reverse Engineering more susceptible to externally induced radiated noise and conducted noise. Even a small amount of parasitic capacitance…
Buffer Logic Noise in Fuel Cut Defencer PCB Card Cloning If we have a high resolution data converter (ADC or DAC) connected to a high speed data bus which carries logic noise generated from Fuel Cut Defencer PCB Card Cloning with a 2 V/ns to 5 V/ns edge rate, this noise is easily connected to the…
Fujitsu Converter PCB Board Repair If the Fujitsu Converter PCB Board has failed due to switching power supply is damaged, An obvious feature to show that Switching power supply damage is there is no display on the screen when power converter on, Fuji G5S uses a two-stage switching power supply, it first intermediate DC circuit…
For the engineer who use converter, Fuji should be an well-known brand, with its simple and practical operation, high cost effective features which has occupied half of China’s converter market, with the passage of time, As a widely used market, converter has entered a high incidence of failure, how to find the root cause of…
