I am trying to understand how the datasheet of the DF40 series of connector from Hirose describe the footprint.

There is a part of the footprint receptacle that is hatched and I don't understand exactly what it means.


Footprint note

Does it mean that the hatched area is part of the pad (copper), but covered by soldermask? But in that case, why cover a part of the pad by soldermask? could it be possible to only have the pad the size of the non-hatched area?

    \$\begingroup\$ That sounds correct. Might be so the pad does not lift/peel (it is a connector after all) but there's no reason to have solder there since it could lift the connector and you can't get to it with an iron anyways \$\endgroup\$
