ALL-CKMD400型晶棒參考面X射線定向儀

ALL-CKMD 400 MODEL X-RAY CRYSTAL ORIENTATION INSTRUMENT BY THE REFERENCE PLANE

晶棒參考面X射線定向儀產(chǎn)品特點(diǎn)

⑴  測量晶棒夾具的結(jié)構(gòu)與功能介紹：

基準(zhǔn)平臺(tái)：此件固定在主機(jī)的臺(tái)面板上，測量時(shí)做水平基準(zhǔn)面，基準(zhǔn)平臺(tái)的右側(cè)為定位面，左側(cè)為夾緊裝置，左側(cè)的夾緊裝置上有夾緊螺釘，設(shè)備配套的夾具在測量時(shí)放于基準(zhǔn)平臺(tái)上。

⑵  測量〈A〉面：晶體主參考面<A>面定向：可測量晶棒直徑為2、4、6英寸,<A>面的θ角：18.917°(18°55′00″)(或按客戶需要做C向、R向)。

①儀器的校準(zhǔn)：用標(biāo)準(zhǔn)晶棒校準(zhǔn)儀器。晶向〈A〉的θ角：18.917° (18°55′00″)

②將裝有晶棒的夾具，清理潔凈后放到儀器的基準(zhǔn)平臺(tái)上，調(diào)整前后位置，使X光能夠照射到晶棒的外圓柱面上，旋轉(zhuǎn)基準(zhǔn)平臺(tái)左側(cè)的夾緊螺釘，把緊。打開X射線光閘，使待測量晶棒在夾具內(nèi)慢慢轉(zhuǎn)動(dòng)，尋測峰值。當(dāng)μA表針為*狀態(tài)時(shí)(即為zui大值時(shí))，保證晶棒不動(dòng)，夾緊晶棒。

③將夾具從定向儀下移出，轉(zhuǎn)到磨床上磨削平面。

④自動(dòng)升降測試。

Features

⑴ Construction and function of crystal clip

Benchmark platforms: 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 .The clip has the screw clamping device.Please put the clip on the horizontal platform when begin to have a testing .

⑵Measuring the < A > direction : crystal main reference < A > flat orientation: it can measure crystal rods for 2, 4, 6 inch in diameter, <A> direction θ angle：18.917°(18 ° 55 '00 ") (or according to customers requirement ,use the C or R direction).

①The calibration of instruments: use a standard crystal rod calibration instrument. Crystal (A) θ Angle :18.917 ° (18 ° 55 ′00 ")

②After cleaning up the clip ,and put it on the horizontal platform for adjusting its position ,in order to enable the x-ray exposure on the outside skin of the cylinder crystal ,and fix the screw on the left of rotated horizontal.Open the X-ray shutter ,and let the crystal rotating slow to find the peak .When the μA meter find the best status (i.e the max.value) ,make sure the crystal being static,and fix it tightly.

③Unload the clip from the instrument ,and put it on the grinding plane of the grinding machine.

④Auto lifting test.
