Testing ESD events
ESD events test check.
Simple description of the different types of electrical resistance used in the context of ESD (ElectroStatic Discharge) surfaces and materials:
- Resistance to Ground (Rg): This is the electrical resistance measured between a point on the surface (for example, a workbench or an ESD floor) and the grounding point.
- Volume Resistance (Rv): This is the internal resistance of the material, meaning the ability of the material itself to conduct or electrically insulate through its thickness.
- Surface Resistance (Rs): This is the electrical resistance that opposes the flow of current along the surface of the material.
- Point-to-Point Resistance (Rpp or Rp): This is the resistance measured between two arbitrary points on the same surface of the material.
