Fujitsu’s FCN-07 DDR-3 DIMM socket is a vertical
mount press-fit socket.
The unique contact structure provides for twin points
of contact that insure that dust is wiped clean when
module is installed.
In addition, the twin points guarantee constant
contact between the module and contact even in a
high vibration environment.
