This board deflection metric provides guidance for mechanical designs that differ from the
reference design for ATX/µATX form factor.
A.2.2 Board Deflection Metric Definition
Board deflection is measured along either diagonal (refer to Figure 14):
d = dmax – (d1 + d2)/2
d’ = dmax – (d’1 + d’2)/2
Configurations in which the deflection is measured are defined in Table 6.
To measure board deflection, follow industry-standard procedures such as IPC for board deflection
measurement. Height gauges and possibly dial gauges may also be used.
