Reverse Engineering Electronic PCB Board Lead Wire

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…

High Frequency PCB Circuit Card Reverse Engineering

In the process of High Frequency PCB Circuit Card Reverse Engineering, the index is usually recorded in the engineer’s catalogue in the form of self-resonance frequency. If the frequency below self-resonance is used directly, the reactance will become positive, mainly because the reactance is the same as the impedance, if the frequency is more than…
