Recommended Routing
Two rows of compliant contacts in the probe make contact
with pads laid down on the surface of the PC board. These
contacts provide an extremely low probe load (<0.70 pF per
channel), and make a good electrical connection with a small
amount of compression force on a choice of standard PCB
platings. Additionally, the pin contact points are free from
the contamination effects that plague other connector- less
probing technologies.
