Abstract:
1. A method of electrically qualifying high speed printed circuit board (PCB) connectors, said method comprising: mounting a PCB connector on a test card, sending bit patterns through said first portion of the test card; evaluating a waveform on the sense line on said second portion of the test card, using a scope, for the bit patterns launched on said first portion of the test card to measure common mode noise; comparing the measured common mode noise of said second portion of the test card to a golden standard, wherein a peak-peak noise swing is used as a metric to determine electrical quality of the PCB connector; wherein, if the measured common mode noise on the PCB connector is worse than the golden standard, then the PCB connector is disqualified, wherein, if the measured common mode noise on the PCB connector is as good as or better than the golden standard, then the PCB connector is qualified, and wherein a first section of the PCB connector connects to said first portion of the test card and a second section of the PCB connector connects to said second portion of the test card.
