We have a board that has an RF shield on one side and ceramic capacitors on the other side. The side with the capacitors is reflowed first, then the other side is reflowed. We have been experiencing cracked capacitors in these boards. My guess is tha

It could be delamination of the layered material of the MLCC caused by thermal shock or a component fabrication defect. For more on MLCC cracks: https://www.avx.com/docs/techinfo/CeramicCapacitors/cracks.pdf

Failure due to board flex cracks persists as the dominant failure mode in multi-layer ceramic capacitors (MLCC). (...) This paper is intended to show the impact of temperature cycling, high-temperature life tests, and multiple bend exposures to the MLCC with this flexible termination.
Failure due to board flex cracks persists as the do
