1 oz 銅箔是指含銅重量為 1 oz/ft2 或 305 gm/m21 oz = 28.34 gm 而銅比重為8.9故含銅體積為 28.34/8.9=3.184cm3=3184mm31 ft2 =93055mm2故其厚度 = 3184/93055 = 0.0342mm = 3.42um因 1 mil = 2.54 um 故 3.42 um = 3.42/2.54 = 1.34mil

對不起小數點點錯.應該改為故其厚度 = 3184/93055 = 0.0342mm = 34.2um因 1 mil = 25.4 um 故 34.2 um = 34.2/25.4 = 1.34mil

請問fumi先生，您所指的銅的比重是指密度嗎?
