Via Stitching auf Flächen

Abgesehen von einer gaaaaaanz leicht verbesserten Abwärme-Verteilung 
dürfte das Vorhaben keine nennenswerten Vorteile mit sich bringen.

Der höhere Bohrer-Verschleiss beim PCB Fertiger ist hingegen garantiert

Dei EMV Tests gehen glaub nur bis 3GHz. Aber man moechte sein Signal ja 
nicht verlieren.
