SHB Express Connector

Amphenol ICC

The connectors at the interface between the System Host Board (SHB) and backplane are defined as x8 and x16 PCIe connectors. The backplane slots that are designed to interface with PCI Express peripherals can be supported with x1, x4, x8 or x16 PCIe connector links. Solder and press-fit connectors are available in standard x1, x4, x8, or x16 link widths. Each serial PCI Express lane is comprised of differential transmit and receive signal pairs that support 2.5 Gb/s data rate in each direction. All connectors fully support SHB Express or PCI Express signal and power requirements, as well as the auxiliary signals at the interface between the system board and add-in card.


  • Press-fit termination to offer processing advantages when backplane thicknesses exceed 2.36mm (0.090")
  • Solder and press-fit connectors available in standard x1, x4, x8, or x16 link widths
  • Complete range of PCI Express connector sizes with through-hole solder-to-board or press-fit termination options
  • RoHS-compliant versions compatible with lead-free soldering temperatures
