As we all know, in the same area, the circular and square product area with the same diameter or side length can be placed is different, and the general square can be put more, in other words, the square has a higher utilization rate of the effective space. So why wafer instead of crystal square? The square DIE, in a circular WAFER always produces a certain amount of space waste, so in the pursuit of the most profitable and efficient modern, such a configuration can continue to use the reason, the circle can stand out in various shapes, It’s worth thinking about. First of all, because of the production process of silicon wafer, the silicon wafer is purified and then melted by single crystal direct drawing method and then cut into pieces. The pull method used in the single crystal direct drawing process is rotary pull. This pull method determines the cylindrical shape of the ingot, thus determining that the wafer is round. But if you look closely, you will find that the wafer is not a standard circle, there are flat grooves or V grooves, this step can help the subsequent process to determine the location of the WAFER, but also marked the single crystal growth metallography, convenient for the subsequent cutting and testing procedures. And the basic cutting is in the edge position, is a certain sense of resource reuse.

The sealing is one of the main factors that directly affect the dehumidification efficiency and stability of electronic dry cabinet. Dry cabinet has single door, double door, three door, four door and six door, an d this equipment adopts certain dehumidification technology to inside effective space, so that the humidity inside can meet the required set value. Normal, the ambient humidity is higher. If the door of the cabinet can’t guarantee sealing, low humidity air in the cabinet and high humidity air outside the cabinet will create convection. If the convection speed is far greater than the dehumidification speed of the electronic moisture-proof cabinet, the humidity of the electronic moisture-proof cabinet will be difficult to reach the set value. EJER dry cabinet adopts magnetic sealing strip, to ensure the air tightness.

Integrated circuit board, in the subsequent production process, there are generally on-line pre-processing procedures, such as burning. In this process, the circuit board will often lead to longer retention time. Many enterprises will useelectronic dry cabinetsto store stranded circuit boards. The following is to say in this process to store circuit board what matters for attention? Integrated circuit board is generally classified as PCB circuit board, and also called multi-layer circuit board, its main prevention after unpacking is to prevent the chips from getting damp. The use ofhumidity control cabinetsis also to prevent the moisture to attack circuit boards. In addition to moisture-proof, the use ofdry storage cabinetscan also reduce the oxidation of metal parts such as circuit board pins and achieve the purpose of anti-oxidation. Therefore,drying cabinetis the best choice for integrated circuit board and other MSD storage. In the process of circuit board burning and recording, one of the different characteristics of chip storage and warehouse storage is that theelectronic moisture-proof cabinet, which is stored, will often open and close. This is also determined by the circuit board needs to be burned out in batches of the process characteristics. The main points for attention in the process are the dehumidification performance of the moisture sensitive level corresponding to the chip, the dehumidification speed of the drying cabinet and the recovery time of the switch door. Generally speaking, the moisture-proof cabinet in the burning process must have fast and ultra-low humidity performance. In this respect, we can refer to our fast ultra-low humidity cabinet introduction. In addition, it is still necessary to pay attention to the protection of static electricity when the dry cabinet is used in this process, which is carried out jointly by the anti-static consciousness of the operator and the anti-static measures of the moisture-proof box. Another point to note is that operators need to take the material in as short a time to complete. Operators are required to place materials in electronic moisture-proof cabinets as far as possible. Good quality protection measures can cause good quality products.

The times are evolving and society is developing. The progress of science and technology is getting faster and faster, people are also more and more critical of the quality of electronic products, only fine, intelligent, mechanized can keep up with the pace of the times, it is not difficult to see that this era is more and more strict with the electronics industry, because people need better products to meet them, so the quality of factory products can only be improved, otherwise it is eliminated by the times. So in the production process, how to solve the v arious productive problems? In today’s electronics industry, the problem of moisture-proof and anti-oxidation has always been a very serious problem. The importance of storage safety of electronic components does not need to be questioned. If you can’t give electronic components products a reasonable environment, then no doubt the production of products must be a problem. There will be quality problems, but what if you have nitrogen cabinet? For the production quality assurance of the factory, many factories have ordered the N2 cabinet from EJER, which ensures the quality of the production products, not only the quality assurance, but also let the customers buy and rest assured. In this era, the competition in the electronics industry is very fierce, in addition to technological innovation, more important is the quality of production products. In the semiconductor industry, the moisture-proof and oxidation-proof requirements of material devices are generally high, so the use of nitrogen supply cabinets also needs high-end, and the EJER nitrogen cabinets have very excellent performance compared with other nitrogen cabinets. So if you buy nitrogen cabinets on the basis of product quality control, you can trust us.
