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…

By Fred Tenzer There are essentially two types of technologies used for monitoring operator wrist straps: Single-Wire Impedance or Dual-Wire Resistance Monitors. Both technologies monitor the function of an operator’s wrist strap, but it is important to understand how these technologies work and the shortcomings of each. Here is some basic historical information on the…

Trustat™ NEW B80 mats are .080″ thick, extruded homogenous vinyl material. It is designed to provide a path to ground and eliminate static charge generation when used as a worksurface table mat, shelf liner, or tray liner. The surface resistance (1 x 10E6 < 1 x 10E9 ohms Rtt) meets the ANSI/ESD S20.20 worksurface required…

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…
“Any auxiliary grounds (water pipe, building frame, ground stake) present and used at the workstation must be bonded to the equipment ground.” A low resistance connector (such as metal wire) should be soldered or mechanically attached electrically connecting the building electrical system AC ground (Equipment Ground) to the Auxiliary Ground. ESD Handbook TR20.20 section 5.1.3…

> by Rick Cardinale, Bird Electronic Bird Electronic, founded in 1942 by J. Raymond Bird, soon became a leader in radio frequency instrumentation. Today, Bird also has moved into digital instrumentation test equipment. With the development of digital instrumentation came the increased need for controls to prevent ESD events. Improving ESD protection has been an…
