A grounded conductor cannot hold a static charge ansi esd 6 1 esd association standard for the protection of electrostatic discharge susceptible items grounding.
Esd grounding mats.
Esd mats are serialized and tested to the latest ansi esd s20 20 standards via nist compliant test equipment.
They are designed for electronic repair or assembly facilities to protect esd sensitive components during the soldering process.
The esd association recommends attachment to ac electrical ground.
The standard method of attachment is to attach the ring terminal from the mat to the center screw of the grounded ac face plate cover.
This is to protect against a highly charged mat or ungrounded surface from discharging instantaneously through the cca and then through the operator to the ground connection that the wrist strap is plugged in to.
Point to point resistance is 10 8 10 9 ohms and point to ground resistance is 10 5 10 6 ohms.
Thus conductive mats should be used near extra sensitive equipment.
Esd wrist straps typically have a 1 meg resistor built into them.
Esd mat assembly and certification to s20 20 standards esd matting configuration assembly and full electrical testing.
All conductive matting and dissipative matting needs to be grounded to function properly.
Static control esd clean room products ship same day.
For this we provide ground cords heel grounders and wrist straps.
The standard used internationally to test anti static mats is esd association standard test method stm 4 1 2017 worksurfaces resistance measurements.
Conductive mats can disperse static electricity quicker than can static dissipative mats.
It recommends two tests resistance measured top to top rtt and resistance measured top to ground rtg.
Esd mats also use a common ground to draw the electrostatic discharge away from offending areas.
Our grounding mats are made of the highest quality materials and to the highest quality standards soft quality conductive animal friendly polyurethane leather mat allows for quick and easy storage making grounding more accessible than ever.
Without that ground the mat could in theory protect the item being worked on at first but would then transfer the esd to the very next thing it comes into contact with the next item the person holding it and then to the item or even.
