ESD damage is not always visible to the naked eye. ESD damage to electronic components can be: • Catastrophic Failures • Latent Defects Catastrophic failure causes a failure in an ESD sensitive item that is permanent. The ESD event may have caused a metal melt, junction breakdown or oxide failure. Normal inspection is able to detect a catastrophic…

ElectroStatic charges and ElectroStatic discharges are different. All material can tribocharge (generate ElectroStatic charges). This is static electricity which is an electrical charge at rest. When an electrical charge is not at rest, but discharges (i.e. ESD), problems can occur. All matter is constructed from atoms which have negatively charged electrons circling the atom’s nucleus…

All US based Desco Industries locations will be closed on Monday May 30, 2016 in observance of the Memorial Day Holiday. Customer service will be closed for the day and no orders will be processed for the day. Normal operations will resume on Tuesday May 31, 2016. Desco Industries, Inc. manufactures ESD control products and…

 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…

A complete static control program must also deal with isolated conductors that cannot be grounded and insulating materials (e.g., most common plastics). If an insulator cannot be removed from the ESD Protected Area, substituted with an ESD protective version, or controlled with a topical antistat, ionization must be used. These insulators are often referred to…

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…
