Checking Esd Mats

Really creative name for the mat huh.

Checking esd mats.

Hence the title ansi esd s4 1 worksurfaces resistance measurements. This condition can cause a short in your components from a rapid discharge of electrostatic energy. Ansi esd s 4 1 2006 provides test procedures for evaluating the electrical resistance of work surface materials. This is the official video from american hakko in this video we test the resistance of an esd mat per standard ansi esd s20 20 using a multimeter versus tw.

A resistance top to top rtt test and a resistance to groundable point rtg test. For verification of mats or work surfaces you can reference the esd association tr53 compliance verification document. The standard recommends us to perform two types of tests on the top surface of a mat used for static control. For testing purposes per esd tr20 20 the correct unit of measurement is surface resistance just ohms.

As esd occurs in a microsecond you need to be able to retain the reading. The following rule applies for resistance testing of esd control items. Digital multimeters use their own battery to power the display and they retain the measurement unlike analog multimeters that return to zero once there is no electrical current. You can perform both tests with an esd meter kit.

Back to top 2. It s particularly popular among cellphone repairmen and custom pc builders. Perform the test at 10 volts. Explanations all anti static mats aka esd mats have one purpose to dissipate the static charge that can and usually does build up on the human body during a typical day in a controlled manner.

Use a digital multimeter to check for esd. Test procedure according to ansi esd s20 20 2014 an acceptable work surface will have a point to point and a point to groundable point resistance of less than 1 0 x 10 9 ohms.
