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.
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?
