Net Antennas Vias Problem
I am working in Altium on a USB-C power supply PCB based on the INN3879C reference layout. I added an array of thermal vias under/near the high-current copper area to improve heat spreading, following the reference board pattern. The vias appear assigned to the correct net, but Altium DRC reports many Net Antennae errors.
The vias are intended for thermal dissipation. Why is Altium flagging these as antenna/dangling net violations, and what should I check to make sure the vias are electrically and thermally connected correctly?” besides net of vias
UPDATE: problem found thanks to ppl comments, i realize it was not connect on the other side of the via to make a full loop
