4000g assembly
4000g assembly
(OP)
I'm working to design a small (~8mm cube, <12grams) electronics package and assembly that can live in an environment with vibration producing accelerations up to 4000g.
Does anyone know if anything like this have ever been done before? The most robust assembly I've found is munitions guidance systems package, but they're not built for fatigue, and helpful details have been hard to find.
I would appreciate any other tips (ranging from preferred IC connection, to robust solder compounds, potting, PWB materials, and anything else) on how to keep this from falling apart.

Never argue with an idiot. They'll bring you down to their level and beat you with experience every time.
RE: 4000g assembly
Do you have any advice on bonding components under this loading so that they don't pop off the board?
Do you have any advice on supporting the board so it doesn't flex beyond it's limits?
