For static hazard control, please use an anti-static tester


According to years of work experience, it has been found that the precision of electronic products is becoming higher and higher, and the requirements for static electricity are getting higher and higher. It appears that production and processing enterprises cannot receive orders because they do not have the conditions for electrostatic discharge. Many companies have begun to do a good job of electrostatic protection, build electrostatic grounding systems, 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 electric charge is an essential physical quantity of static electricity, but on-site measurement is not convenient. It is usually used to measure the electrostatic potential on the surface of the object. The measurement often uses a non-contact electrostatic voltmeter, which does not contact the object under test, so the electrostatic effect on the object under test 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 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 electricity in the area**, and any parameter exceeds the standard That is, 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 equipment. 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 sorted 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 effect be achieved. The overall protection concept must be implemented, and the technologies of equalization, grounding, venting, shielding and clamping must be comprehensively used to form a complete protection system.
