Microcoax connectors enhance flip phones

New flip phones and displays with multi-axis hinges will benefit from Honda's new board-to-microcoaxial connectors featuring the world's smallest pitch of 0.3mm.

New flip phones and displays with multi-axis hinges will benefit from Honda's new board-to-microcoaxial connectors featuring the world's smallest pitch of 0.3mm.

The new LVY-series from Honda Connectors is small enough to fit through the 6mm internal diameter of a modern flip phone hinge, for easier assembly and higher reliability.

As an additional benefit, the LVY-series cable plug mates vertically into the board-mounted receptacle.

This gives designers greater freedom to optimally position the connector, even when the PCB is very densely populated.

Integrated EMI shielding is also provided, with metal-to-metal contact between the mated connector and board-mounted receptacle.

Shielding is more important in highly miniaturised mobile handsets, where the RF stage is positioned close to peripheral interconnects.

There is also a passive latch mechanism, secure against shocks up to 100g, which indicates full mating by an audible click.

First in the new series is a 40-way connector with extremely small mated dimensions of 18.4 x 5.5 x 1.5mm.

Current rating for the Honda LVY series is 0.2A DC per contact, with contact resistance below 70mohm thanks to gold-plated copper alloy conductors.

Maximum voltage is 50V AC.

The connectors will operate over the temperature range -25 to +85C, and up to 95% relative humidity.

Honda Connectors' precision contact stamping and plastic housing injection processes deliver high electrical and mechanical reliability.

The LVY-series is also compatible with automated assembly methods, including common SMT reflow profiles.
