A.2.3 Board Deflection Limits
Deflection limits for the ATX/µATX form factor are:
d_BOL - d_ref ≥ 0.09 mm and d_EOL - d_ref ≥ 0.15 mm
And
d’_BOL – d’_ref ≥ 0.09 mm and d_EOL’ – d_ref’ ≥ 0.15 mm
NOTES:
1. The heatsink preload must remain within the static load limits defined in the processor
datasheet at all times.
2. Board deflection should not exceed motherboard manufacturer specifications.
