When you buy a new computer or new components for your hard-earned money, we recommend adding a few extra slings to make sure your computer is not exposed to any unnecessary risks at the time of assembly.
With an ESD bracelet, you reduce the risk of damaging your static electricity components dramatically.
The bracelet smooths the potential between you and the computer by connecting to the computer's chassis, which means that all static electricity from you and the chassis ends up at the same level. If you touch a sensitive component when you are static charged you run the risk that the flow of electricity will permanently damage the component.
