Technical
characteristics
Vacuum Chamber
Vacuum chamber adopts double
shielding cavity and external cavity structure, to provide the sample test of
extreme pressure of 10-4 pa vacuum environment (when using molecular pump) to
test the low temperature, avoid the water vapor in the air condenses into dew
on samples, to avoid excessive leakage or probe cannot contact electrode and
make the test to fail at the same time, due to the vacuum thermal insulation
effect but effective provide refrigeration efficiency, high temperature test,
to avoid the oxygen in the air oxidation samples, to avoid the sample
electrical error on the physical and mechanical deformation.
Probe arm XYZ regulating mechanism
The XYZ adjusting mechanism of the
probe arm adopts the structure of self-locking lead screw and cross roller
guide rail to achieve the precise positioning of the probe at 10um. The probe
drift is better than the high-precision point needle of 60nm/30mins. Meanwhile,
the three-axis tubular clamp and the three-axis cable with high shielding
function are adopted to achieve the leakage test accuracy of 50FA.
Microscope regulating mechanism
By adjusting the telescopic height
of the support frame and the adjustable seat of the microscope, the microscope
regulating mechanism can observe the 20x eyepiece and 0.8-5 times the zoom
ratio of the objective lens in any area of the sample, so as to realize the
magnification ratio of the sample of 16X-100x.
Refrigerant flow regulation system
The refrigerant regulating system is
composed of the pressure control valve of compressed nitrogen in the duwa tank
and the needle valve of precise regulation to control the low temperature. The
pressure in the duwa tank can be adjusted by adjusting the pressure control
valve of compressed nitrogen pressure, so as to control the pressure flowing
out of the refrigerant and then adjust the flow rate of refrigerant.By
adjusting the precision needle valve and then precise control of refrigeration
flow, the function of accurate low temperature control is finally realized.
Refrigerant Coaxial Loop
Refrigerant coaxial circuit of the
refrigerant from the middle line into the sample set, through the shielding
cavity bottom chamber, in return to the outer coaxial loop back tube, finally
through the vent discharge to outdoor refrigerant coaxial circuit makes the
refrigerants in the process of discharge to exploit, to create a relatively
much lower room temperature environment, inhibits into sample sets of
refrigerant consumption in advance, so as to improve the efficiency of
refrigerant in the refrigeration, less consumption of refrigerant.
Shockproof Platform
Shockproof system USES the import of South Korea's big companies air spring type brace shockproof platform by the shape of the air spring material spring chamber volume and aid tank capacity damping aperture and level regulator and a series of suspension design, to realize the system intrinsic frequency is 1.5 Hz, vertical level of the eigen frequency of 1.2 Hz low natural frequency, load bearing of 400 kg of excellent bearing capacity effectively avoid small to test the vibration of low frequency band.
