In the semiconductor device production workshop, because dust is adsorbed on the chip, the yield of VLSI circuits will be greatly reduced. Operators in the production workshop are wearing clean work clothes. If the human body is static, it will easily absorb dust and dirt. If these dust and dirt are brought to the operation site, it will affect product quality, deteriorate product performance, and greatly reduce the yield. . If the radius of the adsorbed dust particles is larger than the line width and the film thickness is lower, the product will be most likely to be scrapped.
Therefore, it is necessary to establish an electrostatic protection system in the process of production and packaging. IC packaging production lines have stricter requirements on static electricity. In order to ensure the normal operation of the production line, the overall decoration of anti-static building materials is carried out on its clean workshops, and all personnel entering and leaving the clean workshops are equipped with anti-static clothing. Hardware measures are taken. Developed enterprise standards or specific requirements in anti-static aspects to support the normal operation of packaging production lines.
Because there are many types of equipment that can remove dust and static electricity, how to choose the product that suits you mainly depends on the conditions of the production line. The following describes several types of equipment that remove dust and static electricity:
1. Ion air gun: It is hand-held, and its operation mode is very casual. It is more suitable for use in the inspection area. The inspector can pick up the air gun and blow it.
2. Ionic air nozzle: It is a fixed product, small in size and does not take up space. It is more suitable for the assembly line or some small spaces. Can also be made into foot-operated and inductive.
3. Ionic wind snake: It has three styles: ordinary type, induction type and foot type, which can meet the needs of customers in different environments on the production site. It is suitable to be used in a place where there is no room for operation, but it is necessary to adjust the blowing position frequently.
In addition to the above products, an ion fan needs to be installed on some of the assembly lines and operating stations, so as to reduce the accumulation of static electricity and prevent the product from being penetrated unknowingly. You can choose our ion fan, which has a large power consumption area and does not take up working space. You can choose according to the size of the workbench or the width of the assembly line.
