H-300透射电子显微镜无光斑故障的分析维修及探讨

Analyzing servicing and studying on zero spot in H-300 transmission electron microscope

本文对日立工司生产的H-300透射电子显微镜出现的无光斑故障进行了剖析、研究、维修。由于我国很多大专院校及科研机构具有该型电镜,使用年限多数已近二十年,其可靠性正处在高故障区,因此我们在维修时针对绝缘材料的选用、维修工艺等方面做了大量的实验工作并取得了良好的效果。同时我们也对H-300透射电镜故障产生的原因和探头引线的焊接工艺技术等进行探讨,希望该文对同行们有借鉴和帮助。

In this paper,we present analysis,servi-ce and study for zero grating in H-300.Transmission electron microscope made in Japan.It is well known that this kind of electron microscope have been used in most university and institute over twenty years, so all most of the electron microscope have problem in its dependability.In order to analyze and service the electron microscope,we make much efforts in the material chosen and the service technics,the experimental results show that our methods are available for servicing those electron microscope. Moreover,we discuss the failure of the electron microscope and the jointing crafts,these results are useful for those who works in this field.
