comparative method
When checking, you need to prepare a motherboard with the same model as the faulty industrial computer motherboard in advance. Use the correct characteristics to compare against the faulty motherboard to see which module has a mismatch in waveform or voltage, then check for inconsistencies point by point until the IPC fault is found and resolved.
Measurement
