X-RAY荧光测厚仪(X-Ray fluorescence thickness tester)
具体可针对如Sn/Fe(基材)、Zn/Cu(基材)、Ni/Cu(基材)、Cr/Ni/Fe(基材)、Au/Ni/Cu(基材)等数十种电镀工艺镀层进行厚度测量,具有测量精度高、简便快捷、无损的优点,特别是对微薄镀层厚度(一般指小于0.2微米)测量效果较佳。
X-Ray fluorescence thickness tester, being highly accurate, fast and easy-to-operate, non-destructive, is mainly used for the thickness measurements of plating layers, such as Sn/Fe (substrate), Zn/Cu (substrate), Ni/Cu (substrate), Cr/Ni/Fe(substrate) and Au/Ni/Cu (substrate). Especially good for the thickness measurement of extra-thin coatings(generally less than 0.2 um).
