The lead wire of the circuit board and the electronic component has parasitic impedance, as a result of that, extra attention must be paid onto it when Reverse Engineering Electronic PCB Board Lead Wire, also it cannot ignore its influence in the high frequency field like the floating capacity.
The parasitic impedance of the wire often causes the phase delay of the circuit and the reset circuit of the circuit to produce a phase. Cyclotron, which is one of the main causes of vibration, is to use a thick and wide circuit pattern when packaging, and the shorter the wire at the bottom of the electronic component, the better.
Reverse Engineering Electronic PCB Board Lead Wire
engineer also need to prevent broadband transmitters from vibrating when Reverse Engineering Electronic PCB Board Lead Wire. The amplifier used in the broadband field usually has a peripheral compensation capacitor, although the capacitance value can change the amplifier frequency. Features, but increased capacity can effectively suppress the unstable oscillation of the circuit.
Based on the consideration of not sacrificing the frequency characteristics, the wide-amplifier with high input impedance often uses the compensation capacitor. However, the good ground often causes the unstable oscillation of the circuit due to the floating capacity. The effective countermeasure is to install the ferrite at the input end. Dragon material terminal, or cancel the better ground.
Better ground is the basic design of the amplifier for the small broadband field. If the high-input operation-amplifier is used in the front stage and an impedance conversion circuit such as LH0033 is set at the same time, the subsequent equalization operation will be greatly helpful. In addition to the high frequency capacitor, a ferrite core is required to form a filter structure.
