Accurate Measurement in Accordance with ANSI/ESD S6.1, ANSI/ESD S20.20 and ANSI/ESD STM97.1
Do you need to make point-to-point resistance measurements in confined spaces but don’t want to buy the equipment permanently? We offer technical service or rental of the Mini Probe, designed specifically to verify resistivity in hard-to-reach places, fully compliant with ANSI/ESD S6.1, S20.20 and STM97.1.
The mini probe verifies that materials and surfaces are able to conduct static electricity in a controlled manner, preventing the accumulation of charges that could damage electronic components.
In advanced ESD programs, failures are usually not found in the visible areas, but at small points that go unverified.
The Point-to-Point Resistance Mini Probe ensures that every critical area is evaluated, meeting international standards and providing real protection against electrostatic discharge.
Quality managers face situations every day where point-to-point resistance measurement is extremely difficult:
-
High-density server racks: The spaces between equipment are often less than 5 centimeters, making it impossible to use standard probes.
-
Surface-mount technology (SMT) machinery: Feeders, guides and conveyor rails have complex geometries with many recesses.
-
ESD workbenches: Corners, rear edges and areas under fixed instruments require periodic checks that conventional equipment cannot reach.
-
Conductive and dissipative floors: Expansion joints, perimeter edges and areas under heavy machinery need measurements that cannot be made without removing components.
-
ESD footwear and garments: Specific measurement points (heel, toe, wrist) are often hard to reach when the operator is in the working position.
For all of these problems we have the right solution: specialized measurement equipment for proper measurement and review in accordance with ANSI/ESD S6.1, ANSI/ESD S20.20 and ANSI/ESD STM97.1
The ANSI/ESD S6.1-2021 standard establishes grounding systems, Common Point Ground (CPG), and verification of ground paths,
Key requirements of the standard:
-
Test voltage: 10 V or 100 V depending on expected resistivity
-
Electrification time: 30 seconds minimum before recording a reading
-
Relative humidity: 12% ±3% for qualification, or record actual conditions
The ANSI/ESD S20.20-2021 standard specifies the requirements for developing, implementing and maintaining an ESD control program. It is the most widely adopted standard worldwide for the protection of sensitive components.
This standard defines the technical and administrative requirements for implementing a comprehensive ESD control system in electronics manufacturing.
It includes:
-
Resistance limits for work surfaces
-
Periodic verification of floors
-
Control of grounding systems
The ANSI/ESD STM97.1-2021 standard defines the method for measuring electrical resistance to ground through a person wearing footwear, on a floor, using specifically designed electrodes.
Test setup according to the standard:
-
Foot electrode: 254×254 mm metal plate weighing 22.7 kg
-
Hand electrode: cylinder 50.8 mm in diameter, 127 mm long
-
Measurement positions: person standing, hand electrode in palm
-
Test voltage: typically 100 V
-
Typical limit: < 3.5×10⁷ Ω (35 MΩ) for footwear-flooring systems
