  8. A word on staking , and vibration… Thing sthat unscrew or unbolt usually got staked with rtv on our sounding rockets payloads.

    Jarick did point out that you have a package from minicircuits on the board. Sometimes the transformers in them have no mechanical support an you may end up with a broken connection internally… but sometimes they fill the transformer with hot glue

    Also, I don’t see any means of support for the middle of the board. Vibration during launch could literally pop components off of the board.

    Also, we never used SMA connectors. We used SMB sealectros. They do not screw on, they snap on and can swivel freely. So if something pulls on the cable, the connector will rotate. Also, just top be sure we would stake them with a dab of rtv.

    If anything has a tendency to be loose or vibrate or unscrew, stake it or tie it down.

    (your board looks wonderful).
