I'm looking into designing a board for a robotics application that is going to be spinning very quickly, and am wondering if there is anything special to take into account. It's going to be in the ballpark of 6000rpm, with the edge of the board 50mm from the center. That's a constant acceleration of around 2000g, with shocks of a couple times that. If I shock mount the board, that would reduce the sudden acceleration but not the rotational one.
What should I do differently from normal PCB design? Would through hole be better than surface mount? Which way should I orient the board, so that the acceleration is parallel to the board (preferable) or perpendicular? Which way should I orient components? Would conformal coating or potting be a good idea? I'd prefer not to, both for repairability and because of the weight. At what kind of accelerations would the component internals themselves start to break?
Also, maybe this is the wrong place to ask this, but what's the best orientation for a lithium polymer pouch battery in this environment?
