ESD Mats: Dissipative vs Conductive

  • Start date
In summary, dissipative ESD mats have a surface resistance of 10^6 to 10^9 ohms, while conductive ESD mats have a surface resistance of less than 10^6 ohms. This means that conductive mats are more effective at dissipating static charges compared to dissipative mats. The type of ESD mat that is better for your application depends on the required level of static dissipation, with conductive mats being more suitable for sensitive electronic components. However, dissipative mats may be sufficient for applications that do not require a high level of static dissipation. While conductive ESD mats are more effective, dissipative mats may still be suitable for certain applications. It is not recommended to use a

I was reading up on ESD mats.
I don't understand how the dissipative mat works. Does it just dissipate ESD as heat.
But the mat needs to be connected to ground potential. This would make it similar to conductive mats, correct?

ESD mats ARE high resistance conductive mats. they are one in the same

1. What is the difference between dissipative and conductive ESD mats?

Dissipative ESD mats have a surface resistance of 10^6 to 10^9 ohms, while conductive ESD mats have a surface resistance of less than 10^6 ohms. This means that conductive mats are more effective at dissipating static charges compared to dissipative mats.

2. Which type of ESD mat is better for my application?

The type of ESD mat that is better for your application depends on the required level of static dissipation. If your application involves sensitive electronic components, a conductive mat would be more suitable. However, if your application does not require a high level of static dissipation, a dissipative mat may be sufficient.

3. Are both dissipative and conductive ESD mats equally effective?

No, conductive ESD mats are more effective at dissipating static charges compared to dissipative mats. However, dissipative mats may be more suitable for certain applications where a lower level of static dissipation is required.

4. Can I use a dissipative ESD mat on top of a conductive surface?

It is not recommended to use a dissipative ESD mat on top of a conductive surface as this can create a "floating" charge which can damage sensitive electronic components. It is best to use a conductive mat on top of a conductive surface for maximum effectiveness.

5. How do I maintain and test the effectiveness of my ESD mat?

To maintain the effectiveness of your ESD mat, it is important to regularly clean it with a mild detergent and water. You can also use an ESD mat cleaner to remove any residue that may affect its conductivity. Additionally, you can use a surface resistance meter to test the surface resistance of your ESD mat to ensure it is within the appropriate range for its type.
