Surface Resistance Test Kit OTHER CONSIDERATIONS Discipline A significant increase in the discipline of implementing the fundamentals of ESD control noted in ANSI/ESD S20.20 Foreword, calls for: Ground all conductors in the EPA including people Remove all insulators from the EPA or use ionizers for process necessary insulators Package ESD sensitive items going outside the…
Antistatic is the ESD control property properly referred to as “low charging”. This is an important property for all bags used inside or outside of an ESD protected area (EPA). Specifically, it is important that the inside of the bag be low charging, so when the ESD Sensitive Device is inserted into the bag or…

We posted this back in May 2012, and we noticed the video has gone viral recently with major news channels like CBS news. People do not start feeling charges from an ESD event until the discharge is at least 2000 volts while many common components used for manufacturing of electronics are susceptible to 100 volts or less . …

Using a current limiting resistor in the ground cord is the user’s choice; however, the resistor is not for ESD control purposes. The ESD Association standard for grounding is ANSI/ESD S6.1. ANSI/ESD S6.1 recommends a hard ground (no resistor), but allows the use of a current limiting resistor in the mat’s ground cord. “The grounding…
A Faraday cage or Faraday shield is an enclosure formed by conducting material or by a mesh of such material. Such an enclosure blocks external static and non-static electric fields. Faraday cages are named after the English scientist Michael Faraday, who invented them in 1836. An impressive demonstration of the Faraday cage effect is that…
For Compliance Verification periodic testing, how frequently should an ESD control item be checked? Answer: It is user defined, so it is up to you. Best practice is to test each and every ionizer, but you could also decide (if you got good results) to test a percentage of a particular ESD control item. The…
Question: I am confused on ESD connections. I understand that you cannot clip a cord from a wrist strap to the edge of an ESD protective mat. I know that the common cord for wrist straps has 1 megohm of resistance and that the point to connect the wrist strap cord should have less than…
Does it matter where a person should wear the wrist strap? Desco is happy to share our knowledge of ESD control through our Answer’s Database. We have 5 NARTE Certified ESD Technicians, we are a member of the ESD Association, and we have 30+ years of manufacturing products for ESD control. See the following question…
