Do a good job in electrostatic protection, and complete supporting anti-static human body protection tools
The electrostatic parameters concerned in the production process include electric field strength, electrostatic potential, charge and resistivity. The amount of charge is an essential physical quantity of static electricity, but it is inconvenient to measure on-site. It is usually used to measure the electrostatic potential on the surface of the object. When measuring, a non-contact electrostatic voltmeter is often used. Very small. The antistatic performance of an object can be identified by detecting its surface resistivity or volume resistivity, and the electric field strength represents the energy accumulated by static electricity in the working environment, which is very important for the determination of EPA. Commonly used testing instruments include field strength meter (also known as electrostatic voltage tester), human body comprehensive tester, surface resistance tester, etc. The *new comprehensive monitoring equipment can monitor the static state ** in the area, and any parameter exceeds the standard That is, an automatic alarm.
Detection is a necessary means of ESD control and should be carried out in real time in all links of production. Operators must test the performance of hand/ankle straps, anti-static shoes, and anti-static work clothes each time before entering the EPA; a special person must be responsible for EPA inspection and maintenance, and regularly check whether various ESD equipment, turnover containers, and grounding devices meet the requirements of anti-static The requirements of static electricity; management personnel should regularly check the anti-static grounding conditions of each work station, and if they find that they do not meet the requirements, they should make real-time rectification; the test results should be organized and archived and checked as part of the quality management system certification.
Static protection and static elimination is a systematic project. Only by perseverance can the expected results be achieved. The overall protection concept must be implemented, and the technologies of voltage equalization, grounding, discharge, shielding and clamping must be integrated to form a complete protection system. Obvious effect.
The protection of static electricity is imperative. The content and planning of the static protection management system and the disposal of electrostatic discharge sensitive electronic products in electronic manufacturing enterprises involve the design, production, assembly, packaging, storage, transportation and use processes. Static protection must be integrated into every detail. Only in order to provide uninterrupted electrostatic discharge protection for electrostatic discharge sensitive products, can it reduce the damage caused by electrostatic discharge to electronic products.
For the electronics manufacturing industry, the level of ESD protection of an enterprise basically represents its level of product quality control. The establishment of a management system should be based on the actual situation of the enterprise, set up a system management goal table, formulate measures to celebrate, and design a code of conduct , On the whole embodies saving, effective and sustainable development.
A grounding system for electrostatic protection is arranged on the production site, and warning signs are posted everywhere. You can start from the entire production environment, human body static protection, packaging and transportation of molded products, and having a complete set of anti-static systems can more effectively protect electronic products from static electricity.
