ANSI/VITA 48.7-2023, Mechanical Standard for Plug-in units Air Flow-By cool SKU: AV48.7-2023


Mechanical Standard for Electronic Plug-in units using Air Flow-By™ Cooling Technology

This standard defines a detailed mechanical implementation for Air Flow-By cooling and sealing technologies applied to plug-in modules, backplanes, and sub-racks as defined in VITA 46/48. Air Flow-By cooling seals, environmentally and EMI, the PCBA within heat exchanging covers, convectively cooling the assembly without exposing the PCBA to the cooling air.

This revision provides additional design clarity, removes dependencies on external documentation, adds requirements for plug-in module specifications, and updates recommendations to better guide design practice.
