In many places where the electrostatic protection area (EPA) is set up, the testing of electrostatic shoes and wristbands is carried out by the traditional manual login or supervision method, which is not easy to implement or even full of errors, and it is difficult to obtain the trust of customers and management, which also forms a great potential loophole in the electrostatic grounding of personnel;
ESD turnstile gate system for these shortcomings, put forward a direct and effective solution, to ensure that the operators in the EPA area, have done a good job in personnel electrostatic grounding preparation; And combined with the turnstile gate as the control equipment of the people flow channel. It can provide orderly and civilized access for people in and out, eliminate illegal access, and quickly open the gate in case of emergency to organize personnel evacuation. In the design of this solution, we fully consider the protection of product quality as much as possible through this system.
Analysis of access control demand
With the rapid development of the electronic industry, the quality of electronic equipment and components has been put forward with higher and higher requirements. In this way, in the early stage of the production of electronic equipment, the electrostatic test of employees is particularly important, but also to realize the automatic identification of employees.
ESD turnstile gate system integrates computer technology, network communication technology, ESD technology, automatic control technology, and induction card technology to realize automatic identification of employees and rapid passing of an electrostatic test. It is suitable for the electrostatic test control of the passageway in important places such as research institutes, laboratories, and factories.
Access control Security solutions
The traditional electrostatic protection equipment used in most electronic workshops can not effectively eliminate the electrostatic discharge phenomenon, that is, electrostatic discharge (ESD), which is caused by the static electricity carried into the operation room by the operators. In general, the workers in the workshop will not wear wrist strap equipment according to the regulations, and there is no inspector to check the wearing condition.
Even if there is monitoring equipment, the workers can also make themselves out of the monitoring range, which leads to the meaninglessness of the set of static electricity elimination equipment, and the static electricity can not be released in time, resulting in electrostatic neutralization discharge, In the process of electrostatic discharge, a strong current is generated, and the heat is enough to completely melt the internal circuit of the semiconductor chip;
What’s worse is that only one-tenth of this kind of damage will make the whole components fail before the final test, and the remaining 90% will only cause partial damage to the circuit, that is to say, it can make the defects completely ignored through the final test, and lead to early on-site failure after delivery to customers.
As a kind of access control system, access control turnstile equipment can effectively control the access personnel and orderly pass through the channel system, standardize employee management, save enterprise management expenditure and human cost, and realize the automatic management of employees in and out of the workshop.
After a long time of in-depth research and analysis on the sources of static electricity in the electronic industry, and the investigation on the needs of electronic enterprises, through many years of practical experience, we have successfully integrated a set of static electricity system solutions to prevent the generation of static electricity. The system can effectively release the excessive static electricity on the staff, check the qualified wearing condition of the wrist strap, stop the static electricity outside the production workshop, and eliminate the hidden danger of electrostatic discharge. At present, the system has become an important means of quality assurance for electronic manufacturing component enterprises.
Design principles:
Due to the need for safe and efficient management, the design of an anti-static access control system should follow the following principles:
The practicability of the system
The content of the access control system should meet the actual needs, not flashy. If the one-sided pursuit of the leading nature of the system, It is bound to cause too much investment and too far away from the actual needs. Therefore, The practicability of the system is the first principle to be followed. At the same time, the front-end products and system software of the system have good learnability and operability. In particular, the operability enables the management personnel with primary computer operation level to master the operation essentials of the system through simple training, so as to achieve the operation level of completing the duty task.
The stability of the system
Because the access control system is an uninterrupted long-term work system and is closely related to the normal operation of our electrostatic workshop, so the stability of the system is particularly important. The system should have more than three years of successful application experience in the market and corresponding customer groups and customer service system
System security
All equipment and accessories in the access control system operate safely and reliably, It should also comply with relevant Chinese or international safety standards, And it can work effectively in a non-ideal environment. The powerful real-time monitoring function and linkage function fully ensure the security of the user environment.
System maintainability
The maintenance of the access control system in the process of operation should be as simple as possible. The operation of the system can work when the power is turned on, The extent to which you can plug it in. And there is no need to use too many special maintenance tools in the maintenance process. From the configuration of the computer to the configuration of the system, the configuration of the front-end equipment has fully considered the reliability of the system.
When we achieve the lowest system failure rate, we also consider that even when problems occur due to unexpected reasons, we can ensure the convenient storage and rapid recovery of data, and ensure that the channel can be opened quickly in case of emergency. The maintenance of the whole system is online, and the normal operation of all equipment will not be stopped because of the maintenance of some equipment.
The impact of ESD on electronic products is not only the damage of products but also the reliability of products (intermittent loss of function). It will lead to the instability of product performance and increase the number of maintenance. This situation accounts for 90% of electrostatic damage. The implementation of an anti-static access control system can effectively prevent the failure of reliability and other problems caused by static electricity.
The system requirements are divided into the following three situations:
1. The employee can pass the three-stick gate only after the card is verified to be legal. It is required to display in the real-time record whether the card verification is legal or illegal, as well as the record of employees passing the three stick gate;
2. Employees can pass the three-bar brake only after the card and foot static electricity test are passed. It is required to display in the real-time record the records of card verification legal or illegal, the records of foot static electricity test passing or not passing, and the records of employees passing the three-bar brake;
3. Employees can pass the three-stick brake only after they pass the card and static test of hands and feet. It is required to display in the real-time record the records of card verification legal or illegal, the records of hand static electricity test passing or not passing, the records of foot static electricity test passing or not passing, and the records of employees passing the three-bar brake.
Each workshop can customize the test mode flexibly according to its own situation.
