I need to add microvias of 50um diameter with drill size of 47um for 0.4mm pitch BGA package routing. So far i am unable to find options in PADS layout to put such small microvias. I tried to define microvias of 50um dimensions using


Setup>Pad stack>Pad stack type>Via


The probelm is that the software does not accept such small via dimensions. When i put via diameter of 2mil and drill size of 1.85mil, software starts complaining that your drill size is more than via size..:/


Can anybody help. Screenshot is attached
