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…

To obtain technical information and guidance on ESD control, there are a number of sources, many available at no charge. The ESD Association sells most of their documents, but a number are available as complimentary downloads. Per ANSI/ESD S20.20, Compliance Verification of ESD Protected Area’s (EPA) ESD control items is to be per ESD TR53;…
We see many companies with a conductive tile floors that measures mid-10^5 ohm resistance to ground and the operators are wearing foot grounders on each foot that passes the touch-testing, but what peak voltage on the body is generated? Over the years, there have been independent studies conducted per ANSI/ESD STM97.2, Floor Materials and Footwear…

Seeing ElectroStatic Discharge (ESD) damage is basically impossible. Damage to semiconductor device structure is NOT visible at ordinary magnifications of an optical microscope. If the microscope is capable of 1000X-1500X magnifications, you just might be able to “see” something. The method used, only occasionally as there is considerable expense, is by delayering and etch enhancement…
Most people do not start feeling the effect of an ESD event until the discharge is at least 2000 volts. It typically takes a ESD discharge of greater than 2,000 or 3,000 volts for a person to feel the “zap”. The number varies because the sensitivity of people is different and measuring the voltage is imprecise, so…
Written by: Gene Felder, Corporate Product Manager What is the ESD control requirements for battery and pneumatic powered hand tools? From ESD Handbook ESD TR20.20 section 5.5.2.2 “Battery powered and pneumatic hand tools while being held should have a resistance to ground of less than 1 x 10E12 ohms.” If tool’s housing is conductive or…

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…
Continuous or Constant Monitors pay for themselves improving quality, productivity, eliminating wrist strap daily testing and test result logging. “The wrist strap system should be tested daily to ensure proper electrical value. … Daily testing may be omitted if constant monitoring is used.” [Wrist Strap standard ANSI/ESD S1.1-2006 Annex A, 3 Frequency of Functional Testing]…
