        Ultra High Density UHD InterconnectAmphenol's Ultra High Density (UHD) interconnect is a high-reliability packaging solution for airborne, space, shipboard, and ground-based applications. UHD is presently used in all of these environments and meets the requirements of EIA IS-753, DESC 89065, and IEEE 1101.1 to 1101.9


        The foundation of the UHD connector is a downsized version of the proven MIL-C-28859 tuning fork and MIL-C-28754 blade contact technologies. The UHD connector packages 396 contacts with two mounting attachments into the SEM-E format, using an eight row 0.100" X 0.050" staggered grid to optimize trace routing through the backplane.

        Backplane connectors use solderless compliant press-fit contacts. The module connectors are surface mounted to the module using rigid pin or flex-circuit terminations. The UHD connector has been designed to provide signal integrity and interconnect density to meet today's advanced system-level requirements while maintaining a robust design. UHD is based on a modular approach that allows for straightforward incorporation of signal, power, coax, and fiber-optic inserts, as well as EMI shielding, all within the same connector footprint. This modular approach also enables the production of connectors that are longer or shorter than the basic SEM-E format.

            Amphenol's initial product offering for military and aerospace applications was the SEM 40-pin, NAFI-style interconnect, which was co-developed with the US Navy in the late 1960's. NAFI is an acronym for Naval Avionics Facility - Indianapolis. Together we helped develop the form-factor for interconnecting modules and daughterboards through a central backplane. NAFI connectors offer design flexibility, adaptable in two, three, four, and five rows of contacts.


            Amphenol's FM series flexible circuit male blade connectors are designed to meet a wide variety of surface mount module designs. The FM series connectors can be packaged in up to five rows. The standard NAFI interface is maintained while the flexible circuit traces provide the link to the module. The flexible circuit terminations allows for hand soldering or various automated surface mount soldering processes. The aluminum frame is available in many configurations or is custom designed to meet specific customer requirements which can include coax, fiber-optic and power contacts.


            Amphenol's M Series male blade connectors are available with two, three, four and five rows of contacts. The aluminum frame is available in many configurations or is custom designed to meet specific customer requirements which can include coax, fiber-optic and power contacts. The gold plated contact tails are solder coated for ease of application to the daughtercard. The blade contacts can be oriented standard (blade parallel to daughtercard) or reverse (blade perpendicular to daughtercard). The components used by Amphenol have been designed to meet the requirements of MIL-C-28754.
