PCIe Slot Connector for 280-Circuit Motherboard Layouts
The Amphenol FCI 10139595-110T0LF is a 280-position female card edge connector designed for the PCI Express interface. The connector accepts a PCI Express add-in card of 0.062" (1.57mm) nominal thickness. This is the full-length slot — 280 circuits — so it handles x16 mechanical lanes and the full power delivery the PCIe spec calls for on the edge fingers.
Board Retention and Assembly Features
Three mechanical features on this connector address the common failure modes of a surface-mount card edge: a board guide aligns the card during insertion so the contacts don't stub on the slot wall; a locking ramp on each end provides audible and tactile engagement with the card's notch, holding it in place against vibration; and solder retention pads on the SMT tails anchor the connector to the board during reflow and resist the shear force from repeated card insertions.
Contact Finish and Signal Integrity
That plating thickness supports the mating cycle life expected in a PCIe slot — field replacement of graphics or storage cards over the life of the system. The dual-readout contact geometry (contacts on both sides of the card) maintains consistent normal force across the edge fingers.
