Measure: Indicate surface voltage and polarity of objects. Control: Insulators must be identified at an ESD work area and must meet the guidelines in the ESDA’s ESD Control Program Handbook-ESD TR20.20. Non-Process Essential Insulators If items that can charge to 125 volts or more*, then one of the following will be used: Remove the item…
In 1985 Apple produced a service video that explained the importance of ESD control when servicing an Apple II. Steve Wozniak, a co-founder of Apple computers, was featured in the 26 minute video explaining the handling of ESD susceptible devices. Other than the fact that ESD components are smaller and more sensitive than ever (see…

The 38th Annual EOS/ESD Symposium and Exhibits will be held at the Hyatt Regency Orange County, Garden Grove (Anaheim), CA. Desco has been a part of the ESD Symposium for nearly 30 years. Desco employees have volunteered their time to be a part of the ESD Association’s standards meetings, working groups, and other functions at…
The 2007 version of the ANSI/ESD S20.20 was updated in 2014. The ESDA now offers a guided presentation of the changes on their website HERE The JAN/FEB edition of the ESDA’s Threshold details the changes – Significant Changes Made From the 2007 Version To The 2014 Version Of ANSI/ESD S20.20 To download a complimentary .pdf of…

The major advantage* of ESD shoes is that they do not require a tab to connect to the operator. Conductive additives are blended into the sole (inside to outside) of the ESD shoes and connects (through the sweat layer) to the operator’s feet. However, there are a number of other considerations to when selecting ESD…
Most people notice a difference in the ability to generate static electricity when the air gets dryer (the % RH decreases). As an example, walking across a carpet can yield a charge of 35kV at 10% RH [very dry air], but will drop significantly to 7.5kV at 55% RH. In an electronics manufacturing environment lower…
The ideal ESD Control Plan is one that improves productivity, quality, and reliability, in addition to being flexible enough to accommodate changes and improvements in the manufacturing process. ESD Control Plans must evolve to keep pace with costs, device sensitivities, and the way devices are manufactured in the future. The management of an on-going ESD…
As electronic technology advances, electronic circuitry gets progressively smaller. As the size of components is reduced, so is the microscopic spacing of insulators and circuits within them, increasing their sensitivity to ESD. Industry experts estimate that average electronics product losses due to static discharge range from 8 to 33%. Others estimate the actual cost of ESD damage…
When setting up an ESD Protected Area (EPA), it’s important to determine what ESD Control measures are required. Not every EPA will be the same. The key is that an EPA will provide an environment where ESD is managed by 1) minimizing it’s build up and 2) dissipating it quickly without damaging electronic components. Below is an example of what you can…
