Testing an electrical component
First Claim
1. A method of testing an electrical component, the component comprising a printed circuit board (‘
- PCB’
) with a plurality of traces, the traces organized in pairs with each trace of a pair carrying current in opposite directions and separated from one another by a substrate layer of the PCB, the method comprising;
dynamically and iteratively until a present impedance for a pair of traces of the component is greater than a predetermined threshold impedance;
increasing, by an impedance varying device at the behest of a testing device, magnetic field strength of a magnetic field applied to the pair of traces by the impedance varying device, including increasing the present impedance of the pair of traces;
measuring, by the testing device, one or more operating parameters; and
recording, by the testing device, the measurements of the operating parameters.
