Short summary
Because most commercialized current sensors can only measure current flow when a signal line is inserted into a clamp-shaped probe, it is impossible to measure the current waveform of a high-end PCB with a sub-millimeter fine pitch. We developed a pin-type current probe with high sensitivity, targeting the analysis of high-end PCBs. The probe can measure the current waveform by simply contacting the measurement point. This paper reports on the current sensor development.
