The black abstract material which sticks to inside crack of the sample machined by wire-electrode cutting is analyzed and studied by using scanning electron microscope and X-ray energy spectrometer.
应用扫描电镜及X射线能谱仪等设备，对采用线切割制取的裂纹样品内表面的黑色不明物进行了分析。
The cutout chips are characterized by precise sizes, good consistency, and the cutting section is bright, smooth, and flat, without injuring the internal-layer electrode.
切割出的芯片尺寸精确，一致性好，切割断面光滑、平整，不损伤内层电极。
Due to sectional use of the electrode wire, the loss of the electrode wire is small under the condition of fine cutting, so that the cutting precision can be improved.
本发明通过分段使用电极丝，在精切时，电极丝的损耗极小，可提高切割精度。
