How to check whether the anti-static box is qualified
1. Generally, the test is very simple. Put the surface impedance tester du on the static electricity turnover box, press the test button, and the resistance range is 10 to the zhuan6 power to 10 to the 11 power.
2. If the requirements are stricter, the surface static voltage test should be done. The method is to use the surface static voltage measuring instrument to detect the surface static voltage. The national standard & international standard range is: within plus or minus 100 volts
3. The most standard testing method is: 1. High humidity: 50+-5 %RH 23+-3 degrees Celsius for 48 hours to take out volume resistance, surface static voltage, surface resistance test 2. Low humidity: 30+-5% Place it at RH 23+-3 degrees Celsius for 48 hours and take it out for volume resistance, surface static voltage, and surface resistance tests
4. The test result meets the 6-11th power of the national standard, which means that the electrostatic test is qualified, which can meet the trial needs of the production line
5. In view of the quality inspection, generally pick up the electrostatic box and freely fall at a height of 1 meter without damage. The quality is good.
