Anti-static Product Development Trend
Anti-static product development trend
Static electricity is a natural phenomenon that prevails in production and life. As early as the early 1950s, European and American countries began to take precautions in the production of semiconductor devices. China began to pay attention in the late 1960s, and it was actually used in the production of semiconductor devices in the early 1980s.
At present, with the rapid development of modern electronic information industry, the development of microelectronic technology has advanced by leaps and bounds. Large-scale integrated circuits and ultra-large-scale integrated circuits are widely used in the field of remote control technology for aerospace, aviation, computer and program-controlled switches. Therefore, China has put forward higher requirements for anti-static technology in the reform and opening up, especially in the early 1990s.
After nearly ten years of hard work, people have a certain understanding of the harm of static electricity in the field of microelectronics.
In microelectronic devices, the degree of integration is getting higher and higher, and the width of the reticle is becoming narrower. Therefore, in the production process, each process must be prevented from being scrapped due to breakdown caused by electrostatic discharge. In the United States, the annual loss of semiconductor devices due to electrostatic discharge reaches 10 billion US dollars, the United Kingdom reaches 2 billion US dollars, and 70% of Japan's microelectronics scrap losses are caused by electrostatic discharge. What is even more frightening is that some VLSIs have been partially injured at the factory, but they have not been completely disconnected. When installed on a spacecraft, it may cause irreparable accidents. Even on the ground, in the computer room, program-controlled switch room, aerospace command center, due to the electrostatic discharge interference, it will cause distortion, noise, loss of control, garbled and other hazards, which is a very serious problem in the field of microelectronics applications. .
Fortunately, with the increasing awareness of the dangers of static electricity, China's anti-static products have also formed a complete system, only more than 10 manufacturers of steel flooring, the annual demand is several million square meters; The annual sales of anti-static products reached 1.5 to 1.7 billion yuan; moreover, some products entered the international market, with a growth rate of more than 10%.
However, with the rapid development of the anti-static industry, a large number of hidden dangers in the industry are constantly exposed.
The first is in microelectronics applications.
In the design and production, the anti-static factor is not enough. The anti-static requirements in the use environment of the whole machine are not clear enough, so the user can't pay attention to it. The anti-static requirements are not strict enough in the engineering design, and the entire anti-static system is not guaranteed.
Secondly, the quality of anti-static products is uneven, and many of them are still of low quality and inferior quality, especially on anti-static floor materials.
In terms of the substrate material of the composite floor, the ordinary wood board is used instead of the particle board, the ordinary white latex is used instead of the conductive glue, and the ordinary rubber strip is used instead of the conductive rubber strip to occupy the market at a low cost.
In addition, the polytrimide used in most antistatic floor coverings on the market is also a substitute. Its wear resistance is relatively poor, and it is used on steel floors, which is a waste of steel substrates. The cost of using imported veneers or replacing PVC boards is high, and although the quality of the products is improved, it is difficult to market.
As a result of the mutual killing of the price, the quality of the antistatic product is degraded, and the antistatic product does not function as an antistatic.
Once again, there is a lack of professional knowledge during the construction process, so that anti-static products can not play their due role.
During the installation and construction process of anti-static products, some construction teams simply do not understand anti-static knowledge, grounding lines are connected, and even some are not grounded, and so on, all affect the role of anti-static products.
If the above problems are not rectified in time, anti-static will flow in the form, which will cause great losses to the application of modern microelectronics and hinder the popularization of high-tech technology.
Therefore, the anti-static industry association and relevant government departments have adopted a series of measures to promote industry enterprises to adopt passive anti-static technology to reduce or even avoid electrostatic damage through policies and regulations, testing standards, media publicity and professional knowledge popularization.
These measures and actions are undoubtedly greatly promoting the development of the anti-static products industry. Anti-static products such as anti-static workshops, protective clothing, anti-static shoes, and anti-static wrists have emerged.
Before entering the anti-static workshop, it is necessary to check the body charge of the entering personnel. At this time, there is another problem: in the case of manual inspection, many artificial and subjective factors may make the test results not meet the requirements of policies and regulations. So, can you provide a professional, non-human-controlled static detection device? In addition, the static electricity detection and the access control channel management are separate. In this process, there may be a period of time before the entrance is passed or the static detection is passed, and a large amount of static electricity is accumulated. Then, is there a kind of machine that can simultaneously implement the functions of electrostatic detection and access control system management, and does not avoid these situations?
At this time, the ESD anti-static detection access control began to play its role. Anti-static access control ensures that the operator is ready to statically ground the personnel when entering the EPA area. The three-roller gate or other channel device is used as the control device for the flow channel, providing an orderly and civilized way for the entry and exit personnel to prevent illegal In and out, and quickly control the drop in an emergency, organize personnel to evacuate.
As the country attaches more importance to ESD, the anti-static product market will become wider and wider. Anti-static access control as the basic pillar of anti-static products will also usher in a better tomorrow!
