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…
How to choose PCB Board Raw Laminate Material is a quite common subject from the very begining of printed circuit board design, to printed circuit board manufacturing, Choosing a PCB material must strike a balance between meeting design requirements and mass production and cost. The design requirements include electrical and institutional components which can learn…
Relayout Electronic Circuit Board Anti-ESD Schematic Design should consider the circuitry layout of the I/O circuit which should be as close as possible to the corresponding connector, and circuits that are susceptible to ESD should be placed near the center of the circuit, so that other circuits can provide them with a certain shielding effect.…
Reverse Engineering Electronic PCB Card ESD Design provide designer an effective way to improve the ESD performance of printed circuit board, because sometimes the original PCB board esd design is not as good as expectation; If the circuit board will not be placed in a metal chassis or shielding device, solder mask should not be…
When we Clone Electronic PCB Board Layout Design which will normally refers to redraw printed circuit board gerber file, through which can to improve the ESD performance of the whole circuitry system, and in order to realize the purpose, below measure must be taken: 1st of all, Put all connectors aside if possible, if possible,…
