Abstract:
:Everybody has already had the ungrateful experience of walking on a carpet tile and receiving an electric shock just by touching a door knob. What many people don't know is that, simply the fact of walking a few meters over the carpet can generate some kilovolts of electrical charge and cause a damage of some thousand dollars on electronic devices such as computers, radios, electronic controls, etc, due to the fact that they have components sensitive to a few hundred volts or less.The most common way of generating Electrical Static Charge is frictioning two different materials against each other. Electrons are transfered from one surface to the other making one more positive then the other this imbalance can easily reach the order of some hundred volts.Today, the automotive industry uses a large quantity of a wide range of electronic components in its products (cars, trucks, etc.) not only for entertainment, but also on the drive control area, (engine, powertrain control etc.). Where no failure can be admitted because driveability and safety can not be jeopardized.So, it is very easy to undestand why an Electronic Assembly Plant that uses millions of sensitive devices every year needs a well defined plan to prevent the effects of Electrostatic Discharge.
