Conductors Electrical current flows easily Can be grounded Materials that easily transfer electrons (or charge) are called conductors and are said to have “free” electrons. Some examples of conductors are metals, carbon, and the human body’s sweat layer. Grounding works effectively to remove ElectroStatic charges from conductors to ground. The other term often used in…
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…
Trans-Tec America, in collaboration with Restronics New England, presents the 2016 Technology Showcase featuring SMT process technology. See Desco’s product demonstration. Desco will present a demonstration of our ionization and continuous monitoring products. We will be available to answer any of your questions concerning these ESD Control technologies or any other ESD Control topic. When:…

1. Define what you are trying to protect. What is the Human-Body Model (HBM) withstand voltage of the most sensitive item? A prerequisite of ESD control is the accurate and consistent identification of ESD susceptible items. Some companies assume that all electronic components are ESD susceptible. However, others write their ESD control plan based on…
The 37th Annual EOS/ESD Symposium and Exhibits will be held at the Peppermill Resort Hotel, Reno, Nevada. 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 annual symposium.…
A new blog post on the EDN Network titled Static Electricity Aims To Power Wearable Devices discusses how static electricity may be used for energy harvesting to power devices such as fitness bands, medical monitoring systems, and watches. In addition to the discussion about using static electricity for the energy that it can provide, the post…
Paul McNamara’s recent post titled ‘The Shocking Truth (and Lies) about ESD” on the Network World‘s documents some stories of damage caused by ESD. One notes: I once zapped my home’s thermostat when I was attempting to change the temperature setting. The LCD went blank and refused to come back on. I ended up replacing the…
Question: 1) In the scope, 200 volts CDM & 35 volts on isolated conductors are added. What is the intention to add them? Why are both of them determined on the value of 200 volts and 35 volts, respectively? Question: 2) As defined in clause 8.3.1, “If the field measured on the process required insulator…
