摘　　要：片状电阻器是由陶瓷材料和金属镀层构成 ,因不同型号的片状电阻器仅 2mm× 0 .5mm和 2mm× 1mm ,镀层仅 0 .5mm× 0 .5mm ,要从侧面测试片状电阻器镀层的厚度 ,对包埋样品的粘合剂的粘合性能 ,粘合剂的硬度与被测物的硬度是否一致提出了较高要求。经大量实验 ,用快干腻子固定和镶嵌片状电阻器试样 。Flaky resistor is an important electronic component in the field of electronic currently. it is widely applied for modern highly precision electronic devices. Flaky resistor is made of ceramics and metal cladding. Because different types of flaky resistors are only 2mm by 0.5mm and 2 mm by 1mm, and the cladding material part is only 0.5mm by 0.5mm. In addition, the thickness of cladding materials of flaky resistors needed to be measured from side face by metallographic. This requires strict preceding treatment to the sample measure. For sample embedded with different bond. We need consider whether sample and bond is inosculate, sample is fixed, sample reaches ideal effect in grinding and polishing or not. How to treat the sample to meet the need of the metallographic measure? In this article, we make a deep research on the preceding treatment of the sample in the experiment.
