What is Automotive Electromagnetic Compatibility? Electromagnetic compatibility refers to the ability of a device, equipment or system to operate well in the electromagnetic environment in which it is located, and does not produce any unbearable electromagnetic interference in its environment. Automotive electromagnetic compatibility refers to the ability of vehicles or parts or independent technical units…
The trend of high frequency and high speed has brought many new problems to the Automotive Electronic circuit Hardware Reverse Engineer, among which the problem of electromagnetic compatibility is the most prominent. The overall layout of the PCB board, chip selection, circuit wiring diagram, distribution of vias and through holes, ground wire design, the influence…
Pulse Width Modulation (PWM) Schematic Designing, which can generate variable levels of power compared to other less efficient modulation methods. The principle of PWM is used in many applications, such as telecommunications, audio effects and lighting, and electronic devices that can generate PWM signals through a microcontroller. Let’s take a look at the electronic effects…
In the High Speed Electronic Circuit Board Schematic Cloning, the power supply and the ground should be as close together as possible, and no PCB board re-wiring layout should be arranged in the middle. All wiring copper layers are as close as possible to a plane layer, and the ground plane is preferably a wiring…
Set Double Side PCB Layout Wiring Reverse Engineering Constraints firstly must report design parameters, after the PCB layout design is basically determined. The statistical function of the PCB design reverse engineering tool is used to report basic parameters such as the number of networks, network density, and average pin density to determine the number of…
Clone Electronic Circuit Board Gerber File have some items need to be taken care, below points will refer to how to extract layout and schematic diagram from a physical PCB board properly and place components onto the right position: The distance between BGA and adjacent components>5mm. The distance between other SMD components>0.7mm; the distance between…
Printed Circuit Board Gerber File Restoration will needs to take the components arrangement/layout into consideration, because the proper component layout will greatly improve the performance of printed circuit boards, especially for those obselete ones which has been designed and layout long time ago, there are several points must be noted when restore PCB board gerber…
Relayout Electronic PCB Board Circuitry Diagram is necessary for other obsolete circuit board due to the END OF LIFE components used on it which will required to replace with alternatives or improve the electrical/electronic performance stability, modification over the current printed circuit board schematic diagram and layout drawing; B. Layout 1. Set the size of…
Recreate Printed Circuit Board Netlist Drawing is step taken after get the BILL OF MATERIAL ready, so the component arrangement of printed wiring board can be replicated after desolder each one of them off the board, and then prepare the Bill of material list from physical PCB board sample; A. Recreate a netlist 1. The…
Reverse Engineering Electronic PCB Board Schematic Diagram Plan compiling is a critical step for reverse engineering printed circuit board design drawing, a comprehensive and overall plan will ease the whole procedures and improve the working efficiency; Understand the design requirements and develop a PCB board redesign plan 1. Read the schematic diagram carefully and understand…
