ESD - Static Control
in electronics, electronic systems assembly in appliance and auto manufacturing as well as in lab applications

Some examples of ESD ionizers are: The IT-7000, the HM-8000 and the Model 190 series & HPS-III hands free ionization guns

Electrostatic discharge (ESD) is the release of static electricity when two objects come static control ESD IT-7000 Tabtop ionizerinto contact. Familiar examples of ESD include the shock we receive when we walk across a carpet and touch a metal door knob and the static electricity we feel after drying clothes in a clothes dryer. A more extreme example of ESD is a lightening bolt. While most ESD events are harmless, it can be an expensive problem in many industrial environments.

ESD first requires a build-up of an electrostatic charge. This occurs when two different surfaces rub together. One of the materials becomes positively charged; the other becomes negatively charged. When that charge comes into contact with the right material or ground, it is transferred and there is an ESD event. The heat from the ESD event is extremely hot, although we do not feel it when we are shocked.

However, when the charge is released onto an electronic device such as a circuit boardoverhead ESD ionizer, the intense heat from the charge can melt or vaporize the tiny parts in the board causing the device to fail. Sometimes an ESD event can damage a device, but it continues to function. This is a called a latent defect, which is hard to detect and significantly shortens the life of the device

Many electronic devices are susceptible to low voltage ESD events. For example, hard drive components are sensitive to only 5-10 volts or less. For this reason, manufacturers of electronic devices incorporate measures to prevent ESD events throughout the manufacturing, testing, shipping, and handling processes.

Grounding and training operators are very important parts and any program to reduce 190 Gun ESD ionization static contorl gundamage caused by ESD on electronics. However there are a few problems with these two approaches: 1) Non conductive materials can not be grounded. So any non conduce material can hold a change and damage an electronic device. 2) Grounding an operator who is wearing non conductive clothes gives a false sense of security. A charge on the clothes will not be grounded out. 3) People do not always do what they have been trained to do.

One method used to control ESD that is less dependent on grounding and training is ionization in the work area. Ionization for static control produces both positive and negative ions which actively reduces the static change.
