A new isolation structure for crosstalk reduction of pogo pins in a test socket

This paper proposes a new isolation structure integrated in the dielectric holder of a test socket for reducing the crosstalk noise. The isolation structure consists of inserted vias and metallic planes, connecting the inserted vias with ground pogo pins. It can provide better than −20dB crosstalk and reflection noises from DC to 10GHz, with 10dB improvement in crosstalk at 10 GHz.
