LGA1356 Socket
2.1
Board Layout
The land pattern for the LGA1356 socket is 40 mils X 40 mils (X by Y). Note that there
is no round-off (conversion) error between socket pitch (1.016 mm) and board pitch
(40 mil) as these values are equivalent.
In general, metal defined (MD) pads perform better than solder mask defined (SMD)
pads under thermal cycling, and SMD pads perform better than MD pads under
dynamic stress. At this time, complete recommendations for pad definition and pad size
do not exist for the LGA1356 socket. See
definition and pad size.
