The ESD phenomenon is a natural phenomenon that exists objectively and can be produced in many ways, such as contact, friction, and induction. The characteristics of static electricity are long-term accumulation, high voltage, low power, small current and short action time. With the in-depth understanding of the hazards of ESD in recent years by electronics companies, mainstream electronics factories have generally adopted anti-static measures at static sensitive workstations. , And introduced the wrist strap ground resistance tester and other spot inspection equipment, these methods can ensure the effectiveness of anti-static wrist strap and other protective measures to a certain extent. . ESD testing technology is an indispensable and important part of the entire electrostatic protection system. So what is the purpose of ESD testing technology?
1. Provide a basis for judging whether to adopt ESD protection and what level of ESD protection to adopt;
2. Provide technical basis for the technical performance and use effect of various ESD protection materials and equipment;
3. Provide a technical basis for the classification and management of ESD protection materials;
4. Provide a basis for judging the quality of various electrostatic protection projects, whether the design is reasonable, and whether the antistatic performance of the product itself needs to be improved, etc.;
5. Whether ESDS products are qualified, an electrostatic discharge sensitivity test is also required to determine;
6. Test methods are indispensable for research and development, failure analysis, product acceptance, model testing, accident analysis, etc.;
All in all, electrostatic testing technology involves all aspects of ESD protection and is one of the indispensable and important contents of the entire ESD protection. ESD electrostatic protection work is a long-term systematic project. Any mistake or omission in any link will cause the failure of electrostatic protection work.
