What role does ESD program management play in electronics manufacturing?
As an anti-static salesperson, how much customers want to respect the quality of products while respecting the price of the products, but often communicate with the ESD engineers in the electronics manufacturing industry, when the product performance and specifications are suitable for production needs, when entering the procurement process Because the price problem will be denied by the purchase, and even some products are specially made. Due to the special product, the manufacturing cost is relatively higher than the standard product, and the transaction cannot be realized. Many customers' purchases will be determined by the price. They did not consider the consequences of inferior products or products with inconsistent performance on the company, whether the yield will be affected, but to achieve the purpose of completing the procurement task, a very irresponsible attitude towards the company.
In the manufacturing industry, ESD protection is particularly important. Some enterprises also spend a lot of money to create static safety protection. Some of them have implemented static protection problems in various departments, and the results are not satisfactory, and even fail to achieve the expected results. There are many reasons for this problem:
1. There is no strict performance test on the anti-static products of incoming materials, only depending on the appearance of the incoming products.
2. The voltage resistance of electronic components in production is not known, and the circuit design of the products is not comprehensive.
3. The solution formulated by the ESD system is not strictly implemented, and the product rate is seriously degraded due to electrostatic discharge.
4. The electrostatic grounding system is not perfect, and the system resistance connected to the earth is not strictly controlled.
5. During the production process, the failed anti-static products are not eliminated or updated in time, so that the static electricity protection is invalid.
6. In the process of using static protection products, if there is no regular comprehensive inspection, the missed inspection will leave hidden dangers to the production site.
7. When the ESD system is implemented, the thunder is loud and the rain is small. The ESD technicians are not paid attention to the protection process. There is no need to implement the hidden dangers.
8, did not make good use of the economical electrostatic discharge conditions, eye-catching, listen to other people's opinions, there is no actual situation to detect static discharge
10, ESD static protection does not achieve system management, to prevent protection defects, statistics, summary work is not perfect, etc.
Looking at the ESD protection of the electronics industry, we can find more relevant or similar evidence. For example, the ESD protection design test method for IC devices - HBM is to perform ESD testing on two sets of IC pins, and one of the pins must be grounded (this can better reflect the severe ESD conditions).
In the electronics, medicine, chemical and other industries, we need to wear anti-static clothing, but some people do not know why they wear anti-static overalls, or do not know that anti-static overalls are not worn properly, so it is easy to wear them. Do not wear neatly, wear anti-static clothing, do not wear anti-static shoes and so on.
Many people don't know the working principle of anti-static overalls, and even regard it as ordinary tooling. They think that the work clothes have no appearance problems such as deformation, and they can achieve normal anti-static effects, including the anti-static products required for other work. For example, the anti-static wrist strap used by the staff, the service life of the product is usually only a few months, but it does not necessarily deform, only the test can determine its anti-static function attenuation, and the employee mistakenly believes that it is safe. Continue to use, this is quite dangerous, so we must strengthen the daily anti-static knowledge training of employees and the regulation and management of the use of anti-static products. At the same time, the anti-static products provided by the units for employees should be tested regularly and replaced in a timely manner. To ensure the final quality of the company's products.
Some staff members take off their anti-static shoes during work, so they think that it is enough to protect them with anti-static overalls. In fact, this is a very big misunderstanding, and there will also be great security risks. The use of anti-static clothing is not equipped with anti-static dust-free shoes, allowing people to touch the ground, there may be a danger of static discharge, so the staff should have basic knowledge.
