ALL-CKMD 400A型晶棒参考面X射线晶体定向仪

详细介绍

晶棒参考面X射线晶体定向仪


产品特点

⑴  测量晶棒夹具的结构与功能介绍:

基准平台:此件固定在主机的台面板上,测量时做水平基准面,基准平台的右侧为定位面,左侧为夹紧装置,左侧的夹紧装置上有夹紧螺钉,设备配套的夹具在测量时放于基准平台上。

⑵  测量〈A〉面:晶体主参考面<A>面定向:可测量晶棒直径为2、4、6英寸,<A>面的θ角:18.917°(18°55′00″)(或按客户需要做C向、R向)。

①仪器的校准:用标准晶棒校准仪器。晶向〈A〉的θ角:18。917° (18°55′00″)

②将装有晶棒的夹具,清理洁净后放到仪器的基准平台上,调整前后位置,使X光能够照射到晶棒的外圆柱面上,旋转基准平台左侧的夹紧螺钉,把紧。打开X射线光闸,使待测量晶棒在夹具内慢慢转动,寻测峰值。当μA表针为最佳状态时(即为最大值时),保证晶棒不动,夹紧晶棒。

③将夹具从定向仪下移出,转到磨床上磨削平面。

④自动升降测试。

Features

(1) Construction and function of testing crystal bar clamp:

Standard platform: it is fixed on the host machine panel, used for the horizontal platform when testing the sample。The right side of the base platform for locating surface, left platform for clamping, there is stretching screw on the left clamping device, the equipment matched clamp put on the base platform during testing。 

(2) Measuring the < A > surface: crystal main reference < A > surface orientation: it can measure crystal bars for 2, 4, 6 inch in diameter, <A> surface θ angle 18.917°(18 ° 55 '00 ") (or according to customers requirement ,use the C or R direction).

①The calibration of instrument:use standard crystal bar calibration instrument。 θ Angle of the crystal〈A〉surface:18。917 ° (18 ° 55 ′00 ")

②After clean the clamp which hold crystal bar ,and put it on the standard platform of the instrument for adjusting its front and back position, in order to enable the x-ray exposure on the outside surface of the crystal bar, and fix the screw on the left side of rotated standard platform.Open the X-ray shutter, and let the crystal bar rotating slowly inside of the clamp to find the peak value .When the μA meter find the best status (i.e the Max.value), make sure the crystal bar not move,and clamp it tightly.

③Move out the clamp from the instrument ,and move it to the grinding platform for grinding its surface。

④Auto lifting test。


Technical Parameters

Input power: Single phase with AC 220V,50Hz,0.5kW

X-ray tube: Cu target, cooled by fan, anode grounding

Max.tube voltage and current: 30kV, 0~5mA, continuous adjustment. (If the current is above 2.0mA, it will damage the X-ray tube and enlarge the radiative harm)
