Why Eliminate Static Electricity?
To eliminate static electricity, ESD engineers must work tirelessly, as static electricity poses a significant threat to product quality and can have serious consequences. In the electronics industry, ESD engineers often encounter challenges in detecting and eliminating static electricity. Their goal is to find the right equipment to eliminate static electricity and ensure production safety.
Static Electricity Hazard Levels:
The hazards of static electricity: Static voltages below 100V can damage static-sensitive components; 1000V can attract dust; static voltages above 3000V can cause static sparks and even explosions in hazardous areas; and static voltages exceeding 10,000V can damage the human body, clothing, materials, and equipment.
How to Choose an Antistatic Eliminator?
To address various static electricity issues at production sites, Haiweida Hangda offers different types of static eliminators. These include close-range static elimination, long-range static elimination, dust removal by blowing, static elimination in explosion-proof locations, pneumatic conveying, neutral current elimination, and low-cost static elimination with copper wire, antistatic brushes, and antistatic wrist straps. When selecting an anti-static product, it's recommended to consider the following criteria:
1. The ability to remove static electricity depends on the product type and its core technology. For example, the voltage, whether it is AC or DC pulsed, and the structure of the static eliminator (the purpose of which is to eliminate static electricity).
2. The reliability and life expectancy of the product depend on the material and manufacturing quality. For example, the UK-based FRASER uses pure tungsten emitters, which essentially do not lose their high-voltage ionization. When operating at ultra-high voltage (over 20 kV), replaceable pure tungsten emitters are used.
3. Safety: High-voltage ionization can easily cause static sparks or shocks to the human body. The FMX-004 tester can be used to detect the amount of static electricity carried by the human body or to measure the difference in static electricity levels between two people. The static discharge device can be conveniently hung on the wall outside the ESD protection area to prevent charged personnel from inadvertently entering the area. Workers will also find this device useful for regularly checking whether they are generating static electricity while in the protection area.
