Several Hazards of Static Electricity in the Electronics Manufacturing Industry
Static electricity poses several hazards to the electronics manufacturing industry:
1. Dust Adsorption: In modern large-scale integrated circuit production, static electricity easily attracts dust, reducing the insulation strength between core wires, causing chip leakage, shortening lifespan, and even short circuits, leading to chip damage.
2. Electrostatic Field Induction and Discharge: Static electricity can induce strong electric fields at the ends of the oxide film and protruding metal parts of devices or chips due to the tip effect. Because the potential relative to ground differs at different points, when the electric field strength exceeds the insulation strength limit of a certain structural point, it can cause breakdown between dielectrics or between structural points, resulting in component failure or quality degradation.
3. Electrostatic Discharge and Broadband Electromagnetic Pulse Effects: Electrostatic discharge can cause dielectric breakdown in integrated circuit chips, core wire melting, increased leakage current accelerating aging, and changes in electrical performance parameters.
4. Failure Modes of Electrostatic Discharge Sensitive Devices Under the Influence of Electrostatic Discharge.
There are many types of static electricity removal equipment available. Choosing the right product depends primarily on the conditions of the production line. For the above-mentioned hazardous situations, we recommend the following static eliminators:
1. Ionizing Air Gun:
It is handheld and easy to operate. It is suitable for inspection areas; inspectors can simply use the air gun to blow away dust.
2. Ionizing Nozzle:
This is a fixed product, small in size and space-saving. It is suitable for assembly lines or workstations with limited space. It can also be made as a foot pedal or sensor-operated type.
3. Ionizing Air Snake:
It comes in three styles: standard, sensor-operated, and foot pedal, to meet the needs of different production environments. It is suitable for workstations with sufficient space, requiring no manual operation, but where frequent adjustments to the blowing direction are needed.
4. An ionizing fan should also be installed at the workstation to reduce static electricity accumulation and prevent products from being damaged unknowingly. Our TR-002 suspended ionizing fan is a good option. It has a large static elimination area, does not occupy workspace, and can be selected according to the size of the workbench or the width of the assembly line.
