I want to know the answer to the following question:
What force might damage a PCB if large components are surface mounted?
All the background I'm provided with is that "Through-hole manufacture adds to board cost by requiring many holes to be drilled accurately, and limits the available routing area for signal traces on layers immediately below the top layer on multi-layer boards since the holes must pass through all layers to the opposite side.". Is that enough to answer the question?
Answer: no
