Tongda Analysis Machine Purchase Needs To Consider Aspects

    The precautions for purchasing the Tongda analysis machine in the laboratory are generally distinguished by the output value of the Tongda analyzer in the same category of ice machines. The primary goal is the amount of ice produced by the Tongda analyzer every day. Of course, the ideal conditions for writing. Under. The output value of most Tongda analyzer manufacturers is calculated under ideal conditions (such as room temperature 10 degrees, inlet water temperature 10 degrees).

    The capacity of the ice storage bucket is also an important consideration in the selection of the Tongda analyzer. The number of people in the laboratory who are engaged in biological testing has been decided to use a lot. It is assumed that all people use the same amount of demand, and it is best that the amount of ice storage bucket is the same as this amount.

    The Tongda analysis machine is often fully active during the operation. It does not require manual intervention and will actively make ice. When the ice storage tank is full, the machine will take the signal to stop the operation actively. Therefore, the volume of the ice storage bucket is This is the maximum amount of ice that can be taken from this Tongda analyzer.

     In view of the above factors, we can consider the selection from the following aspects:

1. If there are many people in the laboratory doing molecular biology related tests, and often take ice at the same time, it is best to choose a type that has a large amount of ice and a relatively large ice storage bucket (number of people x ice intake per time) ).

2. If there are not many people in the laboratory who do related experiments in molecular biology, and the probability of collecting ice is low, then you can consider choosing a smaller ice storage bucket, and you can choose a smaller model for ice production.

3. If there are many people in the laboratory doing molecular biology related tests, but the probability of taking ice at the same time is small, then you can consider choosing an ice storage bucket with a relatively small amount of ice and a large amount of ice storage. , can also save the cost of the purchase.

The Operation Of The Tongda Analysis Machine

Considered environment

The X-rays of most Tongda analyzers are only emitted directly through the glass package. Choosing a Tongda analyzer has a flawless window depending on the application. Some factors such as low energy flow and equipment conditions will affect the choice. For example, if your Tongda analyzer has an output window, you must pay special attention to its environmental requirements. The 铍 output window consists of a high-purity base metal, typically a 125-μm thick sash. In the metal composition, bismuth, including water, alcohol and acid, is extremely fused. Therefore, if the window exposure time is too long, when they will damage the output window, it will endanger the built-in vacuum purity of the Tongda analyzer and cause damage to the Tongda analyzer. If your window needs to be cleaned, use a copper-copper swab (non-fused) cleaning.

General safety warning

  1. In addition to generating radiation from the output port, the Tongda analyzer also generates radiation from other areas. Any design must incorporate appropriate radiation protection. Don’t assume that the radiation is only emitted from the output port. Be sure to review the Tongda Analyzer Radiation Response Sheet before implementing your design.

2.Tongda analyzes the opportunity to generate heat. In fact, most of the energy input into the Tongda analyzer is consumed in the form of heat. One reason for the premature failure of the Tongda analyzer was caused by improper cooling. Please check in time to ensure that your cooling design is appropriate.

  1. The Tongda analyzer or X-ray source is a high voltage device, so be sure to ground properly. This means that the grounded Tongda analyzer power supply is packaged. Regardless of the X-ray source or its user, the deviation introduced by the power supply can cause serious damage.
  2. The Tongda analyzer requires that its maximum filament current not be exceeded during use. If it exceeds, the filament will overheat, melt and separate, causing the Tongda analyzer to not work. To prevent this from happening, your filament power supply must have an ultra-high current limiter circuit. This ultra-high current circuit value must be set above the published data sheet value, but below the maximum filament rating. It can only be run if your Tongda analysis machineis protected by an ultra-high current circuit.

Tongda Analysis Machine X-ray Tube Work

Since the boiling point of the liquid changes little, it is almost constant temperature, and the working medium with a large vaporization heat can be selected, so that the x-ray tube heat pipe can transfer a large amount of heat under a small temperature difference. According to the temperature range, the x-ray tube heat pipe can be divided into: low temperature (below 0 ° C); medium temperature (200 ° C – 600 ° C); normal temperature (0-20 ° C); high temperature (600 ° C or higher) heat pipe.

The actual working environment temperature of the x-ray tube is between -10 °C and 40 °C, and the tube head is at 0-80 °C. Therefore, the normal temperature heat pipe is used in the anode of the x-ray tube. Therefore, relatively large power must be supplied to the anode, but the efficiency of the X-ray tube is very low, and the electron beam power of 99% or more becomes the anode heat loss, and the focal spot is overheated.

X-ray tubes are an integral part of the Tongda analysis machine. The vacuum inside the tube is not less than 10-4 Pa. The cathode is a direct heating type spiral tungsten wire, and the anode is a metal target inlaid on the end face of the copper block. The target and electron beam energy are selected according to the purpose of the tube, and tungsten is commonly used as a target. The cathode operating temperature is about 2000K, and the emitted electrons are accelerated by tens of thousands to hundreds of thousands of volts and then hit the target surface.

In order to avoid overheating of the anode, different ways of cooling the anode or the tube are employed to reduce the temperature at the focal spot or to tilt the target surface by a certain angle to provide a larger heat dissipation area. As technology continues to advance, there has been an X-ray tube with a control grid between the anode target and the cathode, and pulse modulation is applied to the control grid to control the X-ray output.

The timing repeat exposure can be adjusted by changing the pulse width and repetition frequency. The penetration ability of the X-ray flaw detector depends on the capacity of the X-ray flaw detector. The tube voltage of the X-ray flaw detector is higher. The higher the tube voltage, the harder the X-ray, the greater the energy, the stronger the penetration ability and the penetrating ability. It is proportional to the square of the tube voltage.

In addition, at the same tube voltage, it is also related to the properties such as the density of the material of the workpiece to be inspected, that is, the ability of the workpiece to be inspected to attenuate the X-rays. For heavy metals such as steel and thicker workpieces, X-ray flaw detectors with higher tube voltages should be selected because of their strong ability to attenuate X-rays. For light metals such as aluminum and magnesium and thinner workpieces, tubes can be selected. A lower voltage X-ray flaw detector.

Tongda Analysis Machine For Better Real-time Detection

The Tongda analyzer photoelectric measurement product uses a target-end remote optical path and imaging method. The core part of the probe is a photodetector, each set consisting of an emitting lens and a receiving lens. Light emitted from a point source in the transmissive lens forms a parallel light field with the receiving lens through the transmissive lens.

The parallel light is then focused by the receiving lens, and the image is formed on the receiving unit after passing through the aperture at the focus. When an object passes through an object in the field of view, the occluded portion of the object presents a sharply defined shadow on the chip of the receiving unit.

The Tongda analyzer uses photoelectric conversion and digital processing to calculate the geometry of the object by the width of the shadow. Photoelectric detection is mainly performed by the shadow of the object to be measured at the parallel light vision. Through this method, commonly used diameter detection, width detection, thickness detection, etc. can also be used for straightness detection, slit detection, position detection, concentricity detection, depth detection, and the like. Non-destructive testing has been widely used in the industry, especially online non-destructive testing has been recognized by enterprises. Therefore, the use of various non-destructive testing technologies to research and develop online non-destructive testing equipment is one of the research projects.

In industrial production, not only the working environment is relatively good, but also the environment is slightly poor, accompanied by high temperature, dust and water mist. Therefore, different testing equipment should be developed for different industrial occasions in order to perform real-time detection well.

Tongda Analysis Machine Real-time Imaging

In recent years, with the development of next-generation information technology such as artificial intelligence, big data and the Internet of Things, the global semiconductor industry has ushered in a cycle of prosperity. In order to resolve the contradiction between demand and supply mismatch, China is vigorously developing the semiconductor industry in order to achieve domestic substitution. Since the implementation of the Big Fund in 2014, China’s semiconductor industry chain has developed rapidly, and will continue to strengthen its position in the semiconductor industry in the future.

With the development of technology, the density of semiconductor chip transistors is getting higher and higher, and the complexity and integration of related products are exponentially increasing, which is an unprecedented challenge for chip design and development. On the other hand, with the shortening of the chip development cycle, the success rate for the tape is very high, and any failure is unbearable for the enterprise. To this end, in the chip design and development process, sufficient verification and testing are required. In addition, semiconductor process technology continues to increase, requiring a lot of technical challenges, testing and verification has become more important.

How to conduct semiconductor testing?

Semiconductor testing is mainly to detect the semiconductor front and back processes. The packaging process is: dicing, loading, bonding, plastic sealing, deflashing, plating, printing, cutting and forming appearance inspection. The front side checks whether there are defects affecting the yield on the surface of the wafer, and ensures that the yield of the processing line is controlled above the specified level. Post-testing is mainly used in wafer processing and IC packaging. It is an electrical and functional test to check whether the chip meets the performance requirements.

Semiconductor testing requires a device for both front and back. Tongda analysis machine real-time online imaging equipment accurately detects defects and improves yield through X-ray imaging principles.

How To Make The Tongda Analysis Machine More Accurate

The Tongda analysis machine has a very important position in industrial production activities and plays a role in maintaining the safety and order of production activities. If the detector fails and cannot be processed in time, it will cause serious consequences. Therefore, it is necessary to implement the fault handling and maintenance work of the Tongda analyzer, so as to fully exert its alarm function, maintain life and property safety, and promote industrial activities. Smooth progress.

However, during the use of the Tongda analyzer, the instrument may malfunction for some reasons. The Tongda analyzer indicates that the instability is one of the common faults. Then, what are the reasons for the instability of the Tongda analyzer?
There are four main reasons for the instability of the Tongda analyzer.
1. Because the Tongda analyzer is in a ventilated place, the indicator is faulty due to the influence of the wind direction; the detector is located at the intersection of the airflow, which affects the normal operation of the indicator;
2. The filter of the Tongda analyzer is blocked;
3. The sex Tongda analyzer has a large vibration during use, which affects normal work;
4. The components of the Tongda analyzer are contaminated, making the alarm meter indication unstable.
For the Tongda analyzer to indicate the unstable Tongda analyzer, the following solutions are proposed. If the fault is caused by the first cause, then the location of the Tongda analyzer should be changed. If it is caused by other reasons, then it needs to be cleaned. Filter, replace and install new components.

The Practical Application Of Tongda Analysis Machine

Machine

X-rays are particles that are generated by the transition of electrons in an atom between two energy levels with widely different energy levels. They are electromagnetic waves with wavelengths between ultraviolet and gamma rays. Its wavelength is very short between about 0.01 and 100 angstroms. Founded in 1895 by the German physicist W.K. Roentgen, it is also called the Roentgen Ray. Roentgen rays have a high penetration ability and can pass through many materials that are opaque to visible light, such as ink paper and wood. This invisible ray can cause visible fluorescence of many solid materials, sensitizing photographic film and air ionization. Ultra-hard X-rays having a wavelength of less than 0.1 angstrom are called hard X-rays in the range of 0.1 to 1 angstrom, and soft X-rays in the range of 1 to 100 angstroms.

Tongda analysis machine principle:

Each element in the excited sample emits secondary X-rays, and the secondary X-rays emitted by the different elements have specific energy or wavelength characteristics. The detection system measures the energy and quantity of these emitted secondary X-rays. The instrument software then converts the information collected by the detection system into the type and amount of various elements in the sample.

Therefore, as long as the wavelength or energy of the X-ray is measured, the type of the element can be known, which is the basis of the qualitative analysis of the X-ray. In addition, the intensity of the X-rays has a certain relationship with the content of the corresponding elements, and accordingly, the device is a Tongda analyzer.

Tongda Analysis Machine Protection Comprehensive

X-RAY is an ionizing radiation with a very short wavelength of about 40nm to 100nm. X-ray can penetrate human body, fiber, wood board, plastic, etc. It can penetrate for woodboard of about 1.5cm thickness, for human skin. The penetration ability is stronger, and x-ray can accumulate in the human body. Generally speaking, the greater the amount of x-ray exposure, the greater the damage to the human body. By damaging the white blood cells in the blood of the human body, the number of white blood cells in the blood is reduced, thereby causing a decrease in the immune function of the body, and a serious disease can be caused.

The Tongda analysis machine is a protective and safe inspection device with a housing that blocks x-ray light leakage. In the early days of x-ray discovery, researchers found that x-ray can penetrate most materials, but the lead plate is almost impossible. Crossing. The Tongda analyzer’s outer casing takes advantage of this and uses a steel-lead-steel three-layer protection to prevent x-ray ray seepage. Therefore, although x-ray can cause certain harm to the human body, the x-ray machine equipment can protect the x-ray equipment from the outside by adding a lead-containing casing, which can play a more safe protection for the operator of the x-ray machine. Therefore, operators who use x-ray equipment for a long time need not worry about x-ray damage to the human body. At present, Tongda analyzers are widely used in various industries, such as electronics industry, safety testing, new energy industry, clothing and other fields.

The Composition Of The Tongda Analysis Machine

Industrial Tongda analyzer, a general term for equipment for X-ray or tomographic inspection of the internal structure of an object, including X-ray tube head assemblies, control boxes, and connecting cables. The X-ray device can be divided into a directional type and a circumferential type according to the direction of the X-ray emission and the window range; and can be classified into a fixed type and a mobile type according to the installation form. When x-rays directly illuminate us, interaction with human tissue can cause some changes in the body’s cells, which can destroy parts of the body’s structure.

For example, breakage of a protein or DNA strand may also directly damage cells. In addition, x-rays can form a kind of free radicals through the moisture contained in the human body, thereby indirectly injuring the human body. From the above introduction, x-ray damage to the human body is really great. So, will the Tongda analyzer have such a big impact on the human body when it is working?

In fact, the Tongda analyzer is usually used indoors. After the wall is blocked, the amount of radiation outside the wall can be completely accepted by the human body without affecting it. Even the staff does not need to transmit protective clothing. Now, have you lifted your fear of the Tongda analyzer? As long as we pay more attention and stay away from radiation, our physical health is generally not affected by x-rays.

Tongda analysis machine The principle of industrial ray machines is a non-destructive method that uses X-ray tube X-rays to penetrate substances and have attenuating properties in matter to find defects. X-rays can be used to inspect internal defects in metallic and non-metallic materials and their products. For example, voids in the weld, slag inclusions, incomplete penetration and other volume defects.
