l 分辨率:0.1μm≥10μm,0.01μm< 10μm,0.001μm< 1μm,0.01mils≥1 mil,0.001mils< 1mil
l 厚度測量范圍:化學銅:0.25μm–12.7μm(10μin–500μin)
電鍍銅:2.5μm–254μm(0.1mil–10mil)
l 線性銅線寬范圍:203μm–7620μm(8mil–300mil
l 工作特點:應用先進的微電阻測試技術。系繩式探頭由四支探針組成,AB為正極CD為負極;測量時,電流由正極到負極會有微小的電阻,通過電阻值和厚度值的函數關系準確可靠得出表面銅厚,不受絕緣板層和線路板背面銅層影響。耗損的SRP-4探針可自行更換,為牛津儀器專利產品。探頭的照明功能和保護罩方便測量時準確定位。
