See published article Now Is The Time for ESD Control Programs to be Improved It includes: HUMAN BODY MODEL Part of the challenge may be for the first time needing to handle electronics having a HBM Class 0A withstand voltage. Per the ANSI/ESD S20.20 Foreword: “This standard covers electrical or electronic parts, assemblies and equipment…

An excerpt from Terry Welsher’s InCompliance article titled – The “Real” Cost of ESD Damage about using “split lot” experiments to determine the effectiveness of ESD control when manufacturing electronics. “At the time of the first EOS/ESD symposium in 1979 there were few mature ESD programs, but many companies were trying to establish them. Some of…

Originally Published by InCompliance Magazine- September 2012 Now is the Time for ESD Control Programs to be Improved “Factory ESD control is expected to play an ever-increasing critical role as the industry is flooded with even more HBM (Human Body Model) and CDM (Charged Device Model) sensitive designs.” By Fred Tenzer and Gene Felder ElectroStatic Discharge…

Question: What does an ionizer do? Answer: The primary function of an ionizer is to neutralize electrostatic charges on insulators and isolated (non-grounded) conductors to reduce the magnitude of electrostatic discharges in the ESD protected area. Point-of-use compressed air ionizers combat electrostatic attraction neutralizing charges on particles causing contamination or visual defects on products. Question:…
Relative humidity (RH) directly affects the ability of a surface to store an electrostatic charge. As RH increase, the time a surface will hold a charge will decrease and the dissipation rate will increase. As the RH increases, so does the natural conductivity of the air, but even at 100% RH the increase in the…
The ESD Association provided a recent article for Printed Circuit Design and FAB called titled “The Simple Solution”. To read the entire article, click HERE. The article is a good discussion regarding the importance of measuring in ESD Control situations. Any good ESD Control Plan requires different measuring devices to determine the need for and effectiveness…
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…

HUMAN BODY MODEL The updated standard ANSI/ESDA/JEDEC JS-001-2011, For Electrostatic Discharge Sensitivity Testing Human Body Model (HBM) – Component Level Table 3 has divided the Class 0 classification into two withstand voltage levels with class 0A being less than 125 volt sensitivity, and class 0B being 125 to less than 250 volts. If handling class…
