Commonly used electrostatic protection products
Human body electrostatic protection products
(1) The human body anti-static system includes anti-static wrist strap, work clothes, hat, gloves, shoes, socks, etc.
(2) Anti-static floor includes anti-static terrazzo floor, anti-static rubber floor, PVC anti-static plastic floor, anti-static carpet, anti-static raised floor, etc.
(3) Anti-static operation series: including anti-static: I: as a placemat, anti-static packaging bag, anti-static logistics trolley, anti-static soldering iron and tools, etc.
Electrostatic measuring instrument
(1) Electrostatic field tester: used to measure the surface resistance of the desktop and floor. For planar structure and non-planar occasions, different measuring instruments should be selected.
(2) Wristband tester: Measure whether the wristband is valid.
(3) Human body static electricity tester: used to measure the amount of static electricity carried by the human body, the impedance between the feet of the human body, the static difference between the human body, and whether the wrist strap and grounding are good. Plugs, work clothes, etc. are effective for protection. It can also be used to enter the discharge to isolate the human body static electricity in the workshop.
(4) Megger: used to measure the impedance or resistance of all conductive, antistatic and electrostatic discharge surfaces.
Requirements of anti-static technical indicators in electronic product manufacturing
