Hirose has launched an SMT board-to-board connector that uses a unique 3-piece floating contact system to simplify assembly and support high-speed transmission capability up to 15 Gbps. Designed for high-speed transmission applications that require multiple stacking connectors on the same PCB, the 0.5-mm pitch FX10-3 series connector is the latest addition to Hirose’s FunctionMax family.
The FX10-3 series mezzanine connector’s floating contact mechanism can compensate for alignment errors up to ± 0.3 mm in both the X- and Y-axis direction. This floating feature allows for multiple connectors to be used in a mezzanine design reducing the stress on solder joints caused by misaligned connectors.
The 3-piece connector uses a new design that connects ground pins inside the connector with ground bars. This ground connection design lowers crosstalk, thus improving the insertion-loss to crosstalk ratio and increasing transmission speed capability.
“Featuring a new, patent pending 3-piece floating concept that provides smooth contact movement, the FX10-3 series mezzanine connector saves assembly time and costs when mating multiple connectors on the same printed circuit board. The 3-piece design also offers excellent signal integrity characteristics to deliver 15 Gbps transmission required in high-speed applications,” said Bill Kysiak, Product Marketing Manager for Hirose Electric USA.
Available in 120, 144 and 168 positions, the FX10-3 Series has a stacking height range of 8 to 13 mm with 1 mm increments. Three types of interposers are offered; two that have grounding options with differential impedance values of 100 ohms and 85 ohms; and one interposer that does not provide grounding for all types of signals.
The FX10-3 Series is RoHS-compliant, with an operating temperature range of –55° to 85°C, a rated voltage of 50 Vac, a rated contact resistance of 130 milliohms, and an insulation resistance of 100 megaohms minimum at 100 Vdc.
The FX10-3 Series has already been used in high-speed transmission applications including base station transceivers, medical equipment, office imaging equipment, industrial machinery, servers and more.
