Board-stacking connector eases server management interface

FCI offers its BERGSTAK 0.8mm board-stacking connector system to OEMs, ODMs and independent hardware vendors as a common connector interface for add-in cards in server management applications.

The module cards can use a 120-position plug connector to interface with a corresponding receptacle connector on the baseboard. By selecting connectors that provide 8mm board-to-board spacing, the top of the add-in module will fit typical pedestal or rack servers without intruding into component "keep out" spaces, said the company.

The BERGSTAK 0.8mm pitch connector series offers a wide range of stack heights and circuit sizes to support a large number of mezzanine, board-stacking applications. The connectors are available in sizes from 40 to 200 positions in increments of 20 positions. Available stack heights range from 5mm to 16mm in increments of 1mm.

Options for wider board spacing can provide clearance for taller board-mounted components or increased airflow for cooling. "With stack-height options that provide up to 16mm board spacing, the BERGSTAK 0.8mm system can provide additional flexibility in systems where there are less-stringent height restrictions," said David Sideck, FCI regional market manager, in a statement. "Wider board spacing can be used to accommodate taller baseboard components under the add-in module or to simply provide additional clearance to help address thermal management issues."

All connectors feature blade-on-beam contact design at the mating interface and surface-mount termination at the PC-board interface. Connector polarization at the mating interface, along with ample lead-in angles, produces easily repeatable mating, said the company. RoHS-compliant connectors are available.
