3.3 Types of Materials
In order to mount a specimen on stub for observing, select the adequate size of stub and
consider the types or properties of specimens.
3.3.1 Classification by Height
Materials of low height
Put the carbon tape on the surface of stub plate and then
mount the specimen.
Even materials a little bigger than the stub plate can be
mounted.
Materials of medium height
Put the carbon tape on the surface of stub plate and then
mount the specimen.
Even materials a little bigger than the stub plate can be
mounted.
Materials of high height
Facing the most flat part of specimen downwards, and a
photographing part upwards, put the carbon tape and mount
the material on stub.
3.3.2 Classification by Material
For the pretreatment of specimens, see [3.4 Production of Specimen].
Plastic material
As plastic material has no conductivity, be sure to coat it.
Sometimes apply the sliver paste on the sides of specimen in
order to enhance efficiency.
Metal material
Coating is not necessary for metal material has high
conductivity. In some cases, conduct the coating process in
order to enhance the efficiency.
