Hirose has an established reputation in the industry for manufacturing high quality, innovative connectors. Recognising the rapid and changing 
technological developments in the field of electronics, Hirose have
introduced the FH42 series to meet with the demand for miniaturisation.
The FH42 series has been designed with space saving in mind. The short
mounting depth is only 3.08mm which is one of the world’s smallest mounting depths for a Back-Flip connector. The low height profile is a mere 0.65mm.
Although compact in size the connector is easy to mount on the PCB with double sided contacts. The fully enclosed molded housing structure conceals the exposure of contacts on the bottom face of the connector allowing
conductive traces to run underneath the connector. Solder wicking is prevented by the application of a nickel barrier on the contacts to prevent the travel of solder into the mating contact area.
The insertion of the FPC is user friendly due to the presence of the wide housing entry and tapered contacts that allow the FPC to be inserted from a steeper upright angle, this allows other components to be placed closer to the connector entrance. In addition, it is also possible to insert the FPC horizontally due to the innovative side-catches that have been designed with a curved surface to permit correct positioning of the FPC. When the FPC travels over the side-catches an audible and tactile click confirms correct mating. For additional security, a special cut out in the housing allows a visual check to verify the FPC is positioned correctly. A high FPC retention force of 7.25N
(31 position, horizontal direction) is achieved due to the inclusion of metal fittings situated internally on each side of the housing to hold the FPC tabs firmly in place.
The unique shape of the contacts support FPC retention by applying pressure on to the FPC to further increase the retention. In addition, the contacts fully support the Back-Flip actuator axle during rotation making it more
secure and exceptionally durable.
Ideal applications are LCD displays, digital cameras, PDA’s, POS terminals and many other small
portable devices.
