Rough purification process of diamond powder

Usually, the raw materials of diamond micropowder are mostly low-grade RVD diamond or diamond micropowder synthesized by explosion method. The raw materials themselves contain a small amount of impurities such as graphite, catalyst metal and pyrophyllite. At the same time, a large number of metal impurities will be introduced in the later process of crushing and shaping. High impurity content will reduce the overall hardness of diamond and affect the performance of deep processing tools. In order to meet the requirements of the subsequent classification process for product purity, these impurities must be removed before transferring to the classification process. At present, the purification of synthetic diamond powder is carried out by chemical method and electrolytic purification technology. Due to the diamond raw materials of pyrophyllite and graphite content less. In order to simplify the treatment process, the general crude purification process is no longer specialized treatment, the product has special requirements, after the completion of the classification of the finished product for post-finishing.

Application of Diamond in New Electronic Packaging Substrate

With the rapid development of modern microelectronics technology, electronic systems and equipment are developing in the direction of large-scale integration, miniaturization, high efficiency and high reliability. The increase in the integration of electronic systems will lead to an increase in power density and an increase in the heat generated by the overall operation of electronic components and systems. Therefore, effective packaging must solve the heat dissipation problem of electronic systems. With the materials, devices and other aspects of technical issues continue to overcome, diamond has become a set of high thermal conductivity, good heat dissipation and other advantages in a substrate material, in a higher temperature environment, is the manufacture of low power consumption, high power density devices, the best semiconductor materials, its huge potential to attract more and more researchers into it. The potential of diamond will gradually be developed to meet the needs of the semiconductor industry in the future and occupy a place in the semiconductor electronic packaging materials.

Fine purification of diamond powder

With the development of modern advanced electronic manufacturing technology, it is required to maintain high purity in the processing of electronic products such as single crystal chips, integrated circuit boards, computer hard disk discs, and avoid the introduction of trace impurities that may cause slight changes in the electrical properties of the products. Therefore, the grinding and polishing products for manufacturing high purity products require high purity diamond powder as raw materials. In order to ensure the purity of the treated product, various fine purification processes should pay attention to the sequence of the process arrangement. Since the metal removal process in the post-treatment generally uses high-temperature resistant glass containers, it is easy to cause the wow element to exceed the standard due to continuous stirring and wear, and the chemical reagents used in the acid removal process will corrode the glass containers, so the metal removal process is generally arranged first, and then the acid removal process is carried out to avoid possible cross-contamination between processes. At the same time, it is required to strictly control the quality of rinsing water at this stage to avoid secondary pollution. The whole process of purification due to a certain risk, so the operation essentials must be standardized, the need for professional personnel fine operation.

Quantum technology, how to subvert the future?

Accelerating the development of quantum technology plays a very important role in promoting high-quality development and ensuring national security. The development of quantum technology has great scientific significance and strategic value. It is a major disruptive technological innovation that has an impact on and reconstructs the traditional technological system. It will lead a new round of technological revolution and industrial transformation. Now, basically, high-tech companies all over the world are carrying out fierce research, competition and snatching!!! In particular, Google, IBM and Intel in the United States are racing to speed up the study of quantum computing in order to take the lead and achieve the so-called "quantum hegemony".

One article to understand the classification of graphite tube

Graphite tube is a kind of material used in production and experiment made of graphite. High purity graphite tube is a graphite tube with a content greater than 99.9%, and it is a product with better quality among graphite tubes. Now, let us briefly understand the main classification of high purity graphite tubes. High purity graphite tubes are artificially processed graphite tubes are relatively high taste, for our industrial production, especially in the field of experimental research is a very useful material.

The working process of Shandong automatic weight sorting machine

The working process of Shandong automatic weight sorting machine mainly has the following aspects. First of all, the working process of Shandong automatic weight sorting machine, because when enterprises choose the same product, they will first see whether they need the product from some working processes, so it is particularly important to find out the working process. The first step in the workflow of Shandong full-automatic weight sorting machine is weighing preparation and feeding conveyor speed setting. First of all, it must be ensured that only one product is on the scale during the weighing process. On this basis, effective weighing is guaranteed. The working process of Shandong automatic weight sorting machine sets the standard weight in advance according to the requirements, and sets the qualified range according to the allowable fluctuation value.

Machining accuracy is the degree of conformity between the actual size, shape and position of the surface of the processed parts and the ideal geometric parameters required by the drawings. The ideal geometric parameters, for the size, is the average size; for the surface geometry, it is the absolute circle, cylinder, plane, cone and straight line, etc.; for the mutual position between the surfaces, it is the absolute parallel, vertical, coaxial, symmetrical, etc. The deviation of the actual geometric parameters of the part from the ideal geometric parameters is called the machining error.
