Real-time detection of production process and environment and anti-static
Through continuous testing, it is possible to identify and quantify those areas that really need ESD protection (EPA), concentrate manpower and material resources there, and confirm which ones are electrostatic safe areas, saving unnecessary expenses; ensuring that all people entering the EPA environment And the electrostatic safety of objects; to ensure the normal and effective operation of ESD equipment.
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 on-site measurement is inconvenient. 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 anti-static performance of an object can be identified by detecting its surface resistivity or volume resistivity, and the electric field strength characterizes 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, hand/ankle strap tester, surface impedance tester, electrostatic voltmeter, charge meter and so on.
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 person must be responsible for EPA's inspection and maintenance, and regularly check whether various ESD equipment, appliances, and grounding devices meet the requirements of anti-static The management personnel should regularly check the anti-static condition of each station, and if they find that they do not meet the requirements, they should make corrections in real time; the test results should be sorted and archived and checked as part of the quality management system certification.
Static electricity protection Static electricity elimination is a systematic project. It is necessary to implement the overall protection concept, comprehensively use equalizing, grounding, draining, shielding and clamping technologies to form a complete protection system in order to achieve obvious results.
