Model 850 – Surface Resistance Probe Electrode. Overview: Protect Your Electrostatic Discharge Susceptible Items by ensuring your ESD prevention is working.
The legitimate unit of the surface resistance is also Ohm. Because of that surface resistivity and the surface resistance are often mixed up. In order to differentiate between the two, surface resistiv- Surface resistance in ohms is a measurement to evaluate static-dissipative packaging materials where lower resistance characteristics are required. Now let’s explore the standards and tests that address these measurements. ASTM D-257 Surface Resistivity The typical value of the surface resistance is between 106 to 1012 Ω. A high surface resistance value indicates that the material is more insulative. Critical Environments that Require Surface Resistance Testing Sheet resistance, often called sheet resistivity, is a measure of resistance of thin films that are nominally uniform in thickness.
Third, there is no mention of a 4-point Kelvin probe or ‘spreading resistance’ or even ‘surface resistance’ in the specifications. Contact resistance is measured through the test coupon and coating (top & bottom). It is measured by simply pressing a flat sample between 2 flat, polished copper (or silver-plated copper) contacts at 200 psi.
