Anti-static products refer to all kinds of products that can prevent static electricity.
Electrostatic measuring instrument:
(1) Static electricity tester: a measure the amount of static electricity in a product or a certain location. b measure the static elimination performance of the static eliminator.
(2) Wrist strap tester: Measure whether the wrist strap is effective.
(3) Wrist strap online monitor: monitor whether the wrist strap is damaged and worn well at any time.
(4) Human body comprehensive tester: It can be used to measure whether the wrist strap and anti-static shoes are effective, and it can also measure the comprehensive resistance of the human body.
(5) Surface resistance tester: used to measure the surface impedance or resistance of all conductive, antistatic and electrostatic discharge products.
(6) System monitoring alarm: It can monitor whether the work flow ground line is in good contact with the earth at any time.
Technical index requirements for anti-static in the manufacture of electronic products:
(1) The grounding resistance of the anti-static ground electrode is less than 10Ω.
(2) Anti-static floor or floor mat: surface resistance value of 105-109Ω, friction voltage <100V.
