The press-fit termination means it installs into plated through-holes without solder — a clean, rework-friendly assembly process for backplane or mid-plane boards. The EMI shielded cage contains radiated noise from the high-speed differential pairs in the SAS link. This is a single-port design, 36 circuits wide.
Mounting and Termination: What the Press-Fit and Right-Angle Mean for Assembly
Press-fit termination eliminates the wave-solder step — the compliant pin compresses into the plated through-hole and holds by interference. That means no solder-joint inspection, no reflow profile to qualify, and easier rework if a pin gets damaged. Board layout must account for the cage footprint and the keep-out zone for the mating plug insertion. The press-fit pins also carry the ground return for the shield cage, which is part of the EMI containment strategy.
