A platter is the sheet of pcb,s that came from the PCB assembler witch had been scored but not separated into single units.
it was use separating then that was causing the damage to the caps.

How do you solve it? We have the exact same problem that you and @pdswd described.

Have also personally experienced this issue, where fault was with the board depanelization process.
This wasn’t idle speculation, multi-K dollars and many months were spent on a very exhaustive investigation.
The solution was to have the board pre-routed in the areas where higher stresses were found with the aid of strain gages.

Did you try other capacitor part number to check it also happens with a diferent part number?

 

All MLCCs (Multi Layer Ceramic Capacitors) are prone to flex-crack failures.
There is a lot of information on the web, here I include are a pair of documents. On the Kemet one look for the paragraph: Flex Mitigation.
You can Google the term for additional hits.
