CompactPCI Connectors
Description
The CompactPCI midplane is located toward the middle of the chassis, and each card
slot is equipped with male J1 connectors (pins). The plug-in cards use socket
(female) connectors. The same type of connectors are used on the rear side of the
midplane to accept rear I/O transition modules. Midplane connectors have external
metal shields for proper shielding and grounding in noisy environments. Controlled
impedance minimizes unwanted signal reflections.
