IPC/WHMA-A-620DS - Space and Military Applications Electronic Hardware Addendum

IPC/WHMA-A-620D-S space addendum provides additional requirements to IPC/WHMA-A-620D standard to ensure the reliability of cable and wire harness assemblies that must survive the vibration and thermal excursions encountered getting to and operating in the military and space environments.
