Anti-static measures
Grounding
Grounding is to directly discharge the static electricity through a line to the earth. This is the most direct and effective way to prevent static electricity. For conductors, the grounding method is usually used, such as artificially wearing an anti-static wrist strap and grounding the work surface.
Grounding is implemented by the following methods:
1 The human body is grounded through the wrist strap.
2 The human body is grounded through anti-static shoes (or shoelaces) and an anti-static floor.
3 The work surface is grounded.
4 Test instrument, tool holder, soldering iron grounding.
5 Anti-static floor, grounding pad.
6 Anti-static transfer vehicles, boxes and racks should be grounded as much as possible.
7 Anti-static chair is grounded.
2. Electrostatic shielding
Static sensitive components are exposed to static electricity during storage or transportation. Static electricity can be used to weaken external static electricity.
The most common method of electrical influence on electronic components is to use electrostatic shielding bags and anti-static turnover boxes as protection. Another anti-static clothing for people
Body clothes have a certain shielding effect.
3. Ion neutralization
A. Anti-static meter
1 wrist strap / foot strap / anti-static shoes comprehensive detector - use: for the detection of wrist straps, foot straps, anti-static shoes meet the requirements.
2 When testing the foot strap and anti-static shoes, add a metal plate and the wires connected to the instrument.
3 In addition to electrostatic ion fan detector - use: Regularly check and verify the ion fan balance and decay time to ensure ions
The fan works in a safe range of indicators.
4 Electrostatic Field Detector - Uses: Measure the electrostatic field to reflect the presence of static electricity, read in voltage form, and test the static electricity of the environment.
strength. Generally affected by the environment and the instantaneous characteristics of static electricity, it is difficult to truly reflect the actual situation.
5 Electrostatic Shielding Bag Tester - Use: Used to detect the shielding effect of electrostatic shielding bags.
6 Surface Resistance Meter - Use: Used to measure material surface resistance and volume resistance.
B. Grounding anti-static products
1 Anti-static wrist strap: Widely used in various operating positions, there are many types of wrist straps. It is recommended to use a hand with 1 megaohm resistor.
The wrist strap should have a certain amount of space.
2 Anti-static watch: Remedy for other anti-static measures (such as adding an ion fan, wearing an anti-static heel strap, etc.)
Better antistatic effect. It is not recommended to wear a large number of anti-static watches.
3 Anti-static foot strap / anti-static shoes: After using anti-static floor, the factory should wear anti-static shoelaces or anti-static shoes.
Wear anti-static shoes to reduce the introduction of dust. It is better for the operator to combine the anti-static wrist strap with the effect.
4 Anti-static mat: It is used for laying the surface of each workbench. Each mat has a 1 megaohm resistor on the string and is reliably connected with anti-static ground.
5 anti-static floor:
Anti-static floor is divided into: PVC floor, polyurethane floor, raised floor.
Anti-static wax and anti-static paint: Anti-static wax can be used on various floor surfaces to increase anti-static function and make the floor brighter and cleaner.
Anti-static paint can be applied to a variety of floor surfaces, as well as to a variety of shelves, totes and other containers.
