Looking at my CCU board I have 4 components that are of concern related to vibrations! Top-Left I have a USB connector, but this is for development only so it will not be mounted in production. Top-Right I have DC/DC and connectors that might need support. And in the midle I have done a mistake as I added an old 32Khz crystal for RTC just because I had it in numbers – this is a hole through and the body/legs will be exposed – this I will replace with a SMD component. As for the connector and DC/DC I might need to add glue or supporting mass as I expect that long term exposure to vibration might cause issues.
The next question is if I can use a large speaker and create my own test bench for vibrations?
