Hirose Electric


Hirose has introduced the FX10, a series of board-to-board connectors that support a data transmission rate of >15Gbits/s. The FX10 series is intended for use in systems that need multiple stacking connectors on the same board.

The series consists of surface-mount headers and sockets in a fine pitch of 0.5mm, keeping the board space occupied by the connector to a minimum.

The FX10 series connectors are supplied as a two-piece unit in stacking heights that range from 4mm to 8mm. By using an interposer, a stacking height between 8mm and 13mm in 1mm steps can be achieved. This combination allows a misalignment range of ±0.3mm in the X and Y directions.

The innovative connector design features fixed ground plates on both sides of the header and receptacle for superior transmission characteristics. The connector may also be supplied without the ground plate: in this configuration, the space freed by the removal of the ground plate is filled with additional signal contacts.

Metal fittings are provided to protect against solder peeling and mechanical stress. The connector’s design also provides for strong retention of the connector to the board.
