Reverse Engineering Amplifier Mixed Signal PCB Board Layout Design can use partition design method to reduce the mutual interference between digital and analog signals; Before redesigning PCB board layout for better emc performance, we must understand the two basic principles of electromagnetic compatibility (EMC): The first principle is to minimize the area of the current…
Relayout Printed Circuit Board Gerber File must follow some rules strictly in order to ensure the out of standing performance of PCB Board than original one, because the purpose of re-route multilayer pcb board layout design is to improve the original PCB functionality; Because the impact interference generated by the transient current on the line…
When we are processing Reverse Engineering High Speed Circuit Board Drilling Drawing, the seemingly simple through holes (vias) often bring a large error effect to the redesign of printed circuit board layout. The adverse effects caused by the effect can be tried in the design: 1. From the consideration of cost and signal quality, choose…
Reverse Engineering PCB Board Gerber Through Hole File will normally comes with some Side Effect, the most obvious one is the Parasitic inductance of vias; Similarly, the parasitic inductance and the parasitic inductance of the via hole. In the reverse engineering of high-speed digital circuit board, the harm caused by the parasitic inductance of the…
The greatest side effect of Clone Circuit Board Layout Design Through Hole Drill File is the parasitic capacitance to ground; The via itself has a parasitic capacitance to ground. If the diameter of the isolation hole of the via on the ground layer is known as D2, The diameter of the via pad is D1,…
Through Hole in the PCB Board Layout Reverse Design is playing an critical role, from a design point of view, a via is mainly composed of two parts, one is a drill hole in the middle, and the other is the pad area around the drill hole. The size of these two parts determines the…
Through Hole Application in Reverse Engineering PCB is quite common, especially when redraw the printed circuit board gerber file documents, through hole is also being viewed as VIA which is one of the important components of multilayer PCBs. The cost of drilling holes usually accounts for 30% to 40% of the cost of PCB card…
How to deal with some theoretical conflicts in actual PCB Board Gerber File Cloning: 1. Basically, it is right to separate the analog/digital division to fit for the PCB board design requirement. It should be noted that the signal trace should not cross the moat, and the return current path of the power supply and…
How to solve the problem of signal integrity in high speed PCB Board Design Recreation: Signal integrity is basically a matter of impedance matching. The factors that affect the impedance matching include the signal source architecture and output impedance, the characteristic impedance of the trace of PCB circuit board circuitry pattern, the characteristics of the…
High Speed Electronic PCB Board Design Interference is a subject need to be concerned when reverse engineering high speed circuit board, the basic idea to avoid high-frequency interference is to minimize the interference of high-frequency signal electromagnetic fields, which is also called crosstalk of printed circuit board design. You can increase the distance between the…
