Test cases of anti-static products
1) Wrist strap test: After using for a period of time, the wrist strap is continuously stretched and bent during this process, and the metal wire in some products that are not of a pass quality will break off and thus have no anti-static effect. The person who used it did not know it had failed, and contacted ESDS electrostatic sensitive parts and products, causing electrostatic damage.
2) Anti-static clothing test: There are many low-quality, counterfeit anti-static clothing on the market. Before use it must be tested (mainly triboelectric charge test) to identify its effectiveness. The general conventional method is to use a surface resistance tester and an electrostatic field tester to test the surface resistance and electrostatic voltage of clothes. Mainly depends on whether the conductive fiber is effective. The detailed method refers to the corresponding national standard.
3) Test of anti-static gloves (finger cots): The technical principle is the same as above, mainly to test the surface resistance.
