It improves the manufacturability during wave solder operations.
Big blank areas cause problems somehow, better that the whole board have a
more uniform
distribution of copper on it.

Subject: [SI-LIST] "checkered" copper plane question
Hello all,
I've been hitting a couple embedded design shows lately
and have been seeing a couple prototype boards that have
the top and bottom copper planes 'checkered'
That is instead of a large continuous plane, the plane has
been cut into a grid of 1-2mm squares.
Has anyone else seen this? What are the benifits of this
type of layout?
Thanks,
-Bill
BTW: The guys manning the booth had answers
ranging from 'I don't know' to 'better aestetics' to 'complex proprietary
EMI interfusion grid' :)
