Electronic components to protect against electrostatic ion fans
The entire process of electronic products from the production to the use of the threat of electrostatic damage. From device manufacturing to plug-in soldering, machine assembly, packaging and transportation to product application, it is under the threat of static electricity. In the entire electronic product production process, each small step in each stage, electrostatic sensitive components may be affected or damaged by static electricity, but in fact the most important and easily overlooked is the transmission and transportation of components. the process of. In this process, transportation is easily damaged by the static electricity generated by the external electric field (such as passing near high-voltage equipment, frequent worker movement, rapid vehicle movement, etc.), so the transmission and transportation process need special attention to reduce damage.
Three situations can have the following effects on electronic components:
1. The component absorbs dust, changes the impedance between the lines, and affects the function and life of the component.
2. The element is inoperable (completely destroyed) due to electric field or current damage to the element insulation and conductor.
3. The component is injured due to the soft breakdown of the electric field or the overheating of the current, and although it still works, the life is impaired. In the above three cases, if the component is completely destroyed, it must be detected and eliminated in the production and quality test, with less impact. If the component is slightly damaged, it is not easy to be found in normal tests. In this case, it is often found to be damaged after repeated processing or even when it is used. Not only is the inspection difficult, but the loss is also difficult to predict. Static electricity is as harmful to electronic components as serious fire and explosion accidents.
