How can I check if an anti-static ankle strap is qualified?
The anti-static ankle strap is made of special anti-static polyester cloth. The fiber has strong anti-static properties, which can protect the human body from the electrostatic charge caused by the contact between the electric charge and the object charge. Since the role of anti-static gloves is so great, we must strictly follow the steps in the inspection:
1. Use the same steps to check other samples. Specification of surface resistance: ≥1.0X105 ohms to <1.0X109 ohms
2. The temperature and humidity conditions at the time of inspection are: temperature: 23±3oC, relative humidity: 40%-60%±5%.
3. Check whether the device under test and the megger electrode can be cleaned. If necessary, clean it with a soft cloth dampened with 70% isopropyl alcohol.
4. After the electrode is placed, check the anti-static gloves. Use the 10V file of the megohmmeter to check. If the reading is <1.0X107 ohms, continue to check with this file. If the reading is >1.0X107 ohm, change to 100V for inspection. . After the reading is stable, record the reading and end the inspection.
5. At the time of the first inspection and inspection, the minimum demand for six commodity samples is checked.
6. The surface resistance of the ankle strap is checked. Place the sample to be tested on the insulating board, and then place the electrode of the megohmmeter on the surface of the glove. The electrode should not exceed the template.
Want to use anti-static ankle straps for good protection For damage to electronic products or chips, we must strictly test according to the above rules, in order to get very accurate data for reference.
