Grounding System

Product Description
Grounding system is the most common and effective anti-static method,but routine maintenance is the biggest problem for grounding
system.On one hand, in the case of invisible laying of slot, the grounding circuit will rust, loosen or human error, resulting in poor
grounding (or open circuit), which will cause a great potential damage risk to the ESD sensitive components, and will make the
expensive ESD protection measures fail,on the other hand,to insure the grounding system get the normal function,it needs to spend a
lot of manpower to carry out regular inspection. This grounding system can provide effective solution for those two issues.
