How to cancel the wrist strap in the ESD control scheme
As we all know, static charges can accumulate on a person's body through simple movement, and the charge creates a potential difference between the person and the ground. This potential difference will bring high risks and cause damage to ESD-sensitive devices during ESD.
In order to overcome or minimize the hazards of ESD, workers generally use wrist straps to release the static charge of the human body to the ground to protect ESD sensitive microchips from the risk of ESD damage.
However, the use of wristbands has played a hampering role in many manufacturing processes, and hanging wristbands and messy windings will restrain the staff during the movement of the staff (such as tied to the machine, workbench or desktop) . Slow down the speed of staff processing products.
Frequent moving personnel can hardly bear the restraint of the wrist strap. In this case, the staff can adopt alternative methods, use anti-static shoes to ground, or use it in combination with the wrist strap.
The use of anti-static shoes or ankle straps helps to control the accumulation of static charges in our body. The design principle of anti-static shoes or ankle straps is to provide a path between the body and the ground material to reduce the potential difference of the body.
It is very important to correctly evaluate the charge release ability of anti-static shoes. When workers move on the anti-static floor material, the charge can be released through the shoes.
Specifically, the selection of anti-static shoes for any specific purpose must consider some or all of the following factors:
1. Resistance 2. Permanent anti-static performance 3. Price 4. Maintenance 5. Durability 6. Ergonomics 7. Comfort 8. Smell 9. Compliance with national standards 10. Compliance with international standards
Another thing to consider is that some shoes will leave black marks on the floor when they are used, so you should first consider using non-marking anti-static shoes. This will not only eliminate possible pollution, but also maintain the floor. the goal of.
When choosing anti-static standards, it is a very wise choice to meet both national standards and international standards. It can satisfy a wider range of customer groups.
