？Introduction to ARINC Backplane ConnectorsAviation Radio Incorporated (ARINC) are recognized world-wide and are a leading provider of air transport electronic components and related services. ARINC supplies a variety of certified, high-quality interconnect systems, including backplane connectors - connectors with defined connection patterns that are specifically designed to provide high-speed data transmission.Backplane connectors are typically found in electronic systems with multiple printed circuit boards (PCBs). The connectors provide space-saving connections for multi-PCB assemblies (known as “bussed” circuits). They feature conductive elements that make contact between the PCBs and provide power distribution, or facilitate communication data transfer between individual boards. ARINC backplane connectors are designed to reduce both weight and footprint requirements, while optimising signal integrity and providing consistent quality performance in a variety of harsh environment aerospace applications.Using ARINC Backplane ConnectorsARINC backplane connectors are used in communication systems, such as onboard avionics, satellite terminals and navigation systems, as well as in ground consoles, satellite ground stations, and many other applications. The connectors can be used for the transfer of digital, analogue and embedded data.ARINC backplane connectors are designed for a wide variety of connections, ranging from the simplest configurations requiring just two pins for power, to more complex systems that require multiple pins for communication. They can be used in both stationary and non-stationary installations, charactersied by different temperatures, pressures and vibration levels.Features of ARINC Backplane ConnectorsARINC backplane connectors are highly reliable and provide superior fluid sealing and protection against electromagnetic interference (EMI). The connectors are also known for their low operating voltage drops (VDR) and are capable of carrying high current loads. ARINC backplane connectors also feature higher contact densities than other connector types.The connectors are available in two different sizes: 1.25mm and 1.6mm. They are also well suited for narrow motherboards, such as the 3U Eurocard standard. The connectors offer Polarized Contacts, which are designed to ensure that the system\'s power and signal connections are correctly oriented when plugged-in.The connectors feature two different contact types: Solder Contacts (pins, guards, and blinds) and Post Contacts. The pin, guard, and blind contacts are used for the connection of signal connections, while the post contacts are used for power source connections.ARINC Backplane Connector Working PrincipleARINC backplane connectors use contact materials that are strategically designed for DC voltage applications and other signal connection requirements. The contact material is designed to resist electrical arcing, and corrosion from contact contactles. The connectors are also designed to reduce the impact of mechanical stressors such as vibration, shock, and temperature cycling.ARINC backplane connectors are designed with precise contact insertion depth control and low electrical contact resistance for signal connections. The connectors utilize a high durometer Neoprene O-ring seal, which delivers superior performance in moisture and dust conditions. The connectors also feature a hermetic seal which ensures air tight connections and prevents the ingress of ingress of moisture and dust. The connectors have an integrated mounting system that allows for installation into either a sub-panel or directly into a chassis frame.ConclusionARINC backplane connectors are highly reliable and provide superior fluid sealing and protection against electromagnetic interference (EMI).
