How can electronic products in electronics factories be prevented from static electricity?

As we all know, static electricity has a great impact on how electronic products are damaged, the circuit is quite sensitive to electrostatic high voltage, when people or objects with static electricity come into contact with these components, static electricity will be released, when the electrostatic high voltage impact circuit, the internal oxide film will be broken down and damaged, resulting in damage to components or abnormal operation, so the prevention of static electricity is the key to the electronics industry can not be ignored.

How can we effectively prevent and eliminate potential electrostatic hazards? Rongxin anti-static provides you with the following solutions for your reference.

1. Static electricity prevention in the workplace, the workplace should be equipped with anti-static equipment, such as anti-static workbenches, anti-static work chairs, anti-static floor mats, etc., and the indoor relative humidity should be kept at 40%-60%.

2. The operator should always keep in mind the hazards of static electricity, and should be equipped with anti-static work clothes, anti-static gloves, anti-static wrist straps, etc.

3. Electronic components should also pay special attention to the protection of static electricity in the process of turnover, packaging and transportation, and anti-static turnover boxes should be used in the turnover process. Anti-static turnover rack, the inner packaging with anti-static effect should be used when packing.

The damage of static electricity to electronic components is immeasurable, and all enterprises should take protective measures at every step to minimize the loss.

Anti-static flooring. Anti-static worktop. Anti-static clothing. Anti-static wrist strap. Anti-static shoes. Control humidity. The equipment is equipped with ionic air for static dissipation.

Characteristics of electrostatic damage to electronic products:

1.Concealment The human body cannot directly perceive static electricity unless electrostatic discharge occurs, but the human body may not necessarily have the feeling of electric shock when electrostatic discharge occurs, because the electrostatic discharge voltage that the human body can perceive is 2 3 kV, so static electricity is hidden.

2.Potential: The performance of some electronic components after electrostatic damage is not significantly reduced, but multiple cumulative discharges will cause internal damage to the device and form a hidden danger. Therefore, static electricity has the potential to damage the device.

3.Randomness Under what circumstances can electronic components be damaged by static electricity? It can be said that from the time a component is created until it is damaged, all processes are threatened by static electricity, and the generation of these static electricity is also random.

The damage is also random.

4.Complexity The failure analysis of electrostatic discharge damage is time-consuming, troublesome and expensive due to the fine, fine and micro structural characteristics of electronic products, and requires high technology and often requires the use of high-precision instruments such as scanning electron microscope.

Even so, some electrostatic damage phenomena are difficult to distinguish from damage caused by other causes, leading people to mistakenly think that electrostatic damage failure is other failure. This is often attributed to early failures or failures with unknown circumstances before electrostatic discharge damage is fully understood, thus unconsciously obscuring the true cause of failure. Therefore, the analysis of electrostatic damage to electronic devices is complex.

The hazards caused by static electricity to the production of electronic products.

The harm caused by static electricity to the production of electronic products is mainly in the following aspects.

1) Electrostatic adsorption of dust in the air can easily cause short circuits between device leads.

2) Electrostatic discharge damage, so that the component is damaged and cannot work.

3) Electrostatic discharge, heat generated by electric fields or currents that damage the element.

4) The amplitude of electrostatic discharge is very large, and the electromagnetic field with an extremely wide spectrum (from tens of trillions to several gigabits, stacked hundreds of volt meters) causes electronic products to be damaged by electromagnetic interference.

5) Rework and repair of products damaged by electrostatic discharge, increase production costs, and affect the economic benefits of enterprises.

To sum up, electrostatic hazards exist in the whole process of electronic product production. The analysis results of electrostatic hazards in the production process of an electrical assembly workshop are shown in Table 2. If the parts of the production process that are susceptible to electrostatic damage are controlled, the degree of electrostatic hazards in the production process will be minimized.

The physical properties of static electricity are: attraction or repulsion, and there is a potential difference with the earth, which will produce a discharge current. The following 3 properties are the 3 types of interference with electronic components:

1 Electrostatic discharge, heat generated by electric fields or currents, causing injury (potential damage) to the component. 2. Electrostatic discharge destroys, so that the component is damaged and cannot work (completely destroyed). 3. Electrostatic adsorption of dust, reduce the insulation resistance of the component (shorten the life).

The harm caused by static electricity to the electronic dismantling factory:

1. Static electricity adsorbs dust and reduces the insulation resistance of components.

2) Electrostatic discharge damage, so that the component is damaged and cannot work.

3. The heat generated by the electrostatic discharge electric field or current injures the components.

4. The electromagnetic field generated by electrostatic discharge has a large amplitude, reaching hundreds of volts per meter, and the spectrum is extremely wide and up to several gigabits, causing interference or even damage to the electronic reed generator.

Summary. Dear, I am glad to answer for you, the four characteristics of static electricity causing damage to electronic products are concealment. The human body cannot directly perceive static electricity unless an electrostatic discharge occurs, but the human body may not necessarily feel an electric shock when electrostatic discharge occurs.

The xing energy of some electronic components after being damaged by electrostatic electricity does not decrease significantly, and there are random and complex xing.

Dear, I am glad to answer for you, the four characteristics of static electricity to electronic products are the hidden stove reputation xing. The human body cannot directly perceive static electricity unless an electrostatic discharge occurs, but the human body may not necessarily feel an electric shock when electrostatic discharge occurs. There is no significant decrease in the xing energy of some electronic components after electrostatic damage, and there are still complex xing in random and complex xing.

The sub-products are related products based on electric energy, mainly including: watches, smart phones, televisions, DVD players, VCDs, SVCD, VCDs, VCDs, VCRs, video recorders, radios, cassette recorders, combination speakers, laser record computers, game consoles, mobile communication products, etc. Because the early products were mainly based on electron tubes, the original disappeared traces, so it was called electronic products.
