Hazards of Electrostatic Discharge and Avoidance Methods
Nov. 19, 2021
Electrostatic discharge caused by component breakdown damage is the most common and serious electrostatic hazards of the electronics industry, it is divided into hard breakdown and soft breakdown. Hard breakdown is a one-time cause of component media breakdown, burn or permanent failure; soft breakdown is caused by the device's performance degradation or parameter index decline. How can we use spacer tapes or other anti-static electricity things to prevent them? TONGXI shares with you.
Damage to electronic products
1 electrostatic adsorption of dust, reduce the insulation resistance of components (shorten the life).
2. electrostatic discharge damage, so that the component damage can not work (complete destruction).
3. electrostatic discharge electric field or current generated by the heat, so that the components are injured (potential damage).
4 electrostatic discharge generated by the amplitude of the electromagnetic field is very large (up to several hundred volts / m) extremely wide spectrum (from tens of megawatts to several gigawatts), the electronic device caused by interference or even damage (electromagnetic interference)
If all the components are damaged, it will be detected in production and quality control and excluded, the impact is small. If the components are slightly damaged, it is not easy to find under normal testing, in this case, often due to multi-layer processing, or even in use, only to find the damage, not only is not easy to check, and its losses are also difficult to predict. It takes a lot of manpower and financial resources to identify all the problems, and if the fault is detected only when it is in use, the loss may be huge.
How to avoid it?
Static-sensitive components and printed circuit boards in the production process between the process of transfer and storage, must use anti-static loading boxes, component boxes, crates, turnover trays, etc.. To prevent the accumulation of electrostatic hazards. Static-sensitive components and printed circuit boards, as finished products for packaging must be used anti-static shielding bags, bags, boxes, strips, baskets, etc., to avoid electrostatic damage during transport.
Electronic products in the production process, its components, components finished products are often in contact with equipment and tools, separation, friction and electrostatic generation, must use anti-static pads, turnover trolley, maintenance kit, tools, work chair (stool), etc., and through appropriate grounding, so that the rapid discharge of electrostatic.
Understand the production process electrostatic starting situation, the measurement of electrostatic, mainly on the electrostatic voltage, material resistance, grounding resistance, electrostatic off decay, electrostatic power, electrostatic eliminator dissipative performance, fabric charge surface density, etc.
Electrostatic protection is a system engineering, any link of omission or failure, will lead to the failure of electrostatic protection work, must be prevented at all times, everyone to prevent.
Where can I buy anti-static products
TONGXI's Black conductive film and its processed products have good mechanical properties, the accumulated charge on the packaged protection products can be well discharged through the film body, which can protect electronic sensitive components from electromagnetic waves and static electricity; opaqueness can prevent damage to photosensitive components and products during transportation, storage, etc. These products are widely used in: clean room, purification workshop, photovoltaic power plant, LED factory, PCB factory, electronic factory, electrical factory, electronic equipment, wafer, LCD/LCM/LED, optoelectronic, chip semiconductor, laser head, pharmaceutical, chemical equipment, precision equipment, medical equipment, microelectronics industry, aerospace, military, electronic components, optoelectronic products, electronic devices, liquid crystal products, optoelectronic Integrated products and other requirements grade production area.
