0.4mm has a pad size of 1.00mm whilst in the VIA chart, a 0.4mm hole has a pad size of between 0.65mm and 0.8mm. I realise there is no solder fillet required on a via but have been tearing what little there is left of my hair out trying to figure out how the VIA pad is calculated and if it is defined anywhere in IPC
