To our boards done in supermax ecad we send a text file with this kind of content together with the normal drill file: T1 VH DIA = 0.3 QTY = 1264 T2 VH DIA = 0.5 QTY = 20 T3 VH DIA = 0.8 QTY = 6 T4 PTH DIA = 0.9 QTY = 8 T5 PTH DIA = 1 QTY = 82 T6 PTH DIA = 1.1 QTY = 2 T7 PTH DIA = 1.3 QTY = 100 T8 PTH DIA = 3.2 QTY = 4 T9 PTH DIA = 3.5 QTY = 8 T10 NP DIA = 1.1 QTY = 1 T11 NP DIA = 1.6 QTY = 1 T12 NP DIA = 2 QTY = 2 T13 NP DIA = 3.5 QTY = 2 TPH - plated hole VH - via hole (plated) NP - not plated The reason for separating TPH and VH is that there might be different tolerance requirements. Would be great if this kind of list could be generated from pcbnew! // Magnus
