[PCB_FORUM] Re: antenna vias

Mashak, I have stitched a?brd with gnd vias while some are flagged as antennas 
vias, others are not flagged. 

origin-xy:??? (2160.00 2445.00) 

? part of net name:? GND
? Connected shapes:??? 3 ( TOP L02 L03 )

origin-xy:??? (2425.00 2430.00) 

? part of net name:? GND
? Connected shapes:??? 4 ( TOP L02 L03 BOTTOM )

I'm assuming, since the first via makes no connection to bottom side, then this 
via is flagged as an antenna via. 

where is the feature for removing the unconnected vias?

Thanks for you help.
Sam

As per me Dangling vias orphan vias are called as Antenna Vias in case of HS 
boards. If you have SPB16.2 then there is a feature of Removing all the 
unconnected vias.

Report methodology:

? - Dangling lines have at least one end not connected.

? - Dangling vias have one or no connection

???? ?- Plus are not a testvia or a thieving via.

? - Antenna vias do not have connections on their start and end layers.

????? - Plus they are not a thieving vias.

????? - Optionally, VOLTAGE nets, testvias and through vias can be suppressed 
with

??????? the environment variable report_antennavia.

????? - Section may be suppressed by variable report_noantennavia.

? - In all cases output is suppressed if an object has the OK_DANGLE

??? property or is not part of the current partition.

What is a antenna via? The "dangling line report" flags this.

Thanks
