Computer motherboard static electricity how to do

To prevent static electricity, first of all to understand what is static electricity, how electrostatic is produced. Static electricity (static electricity) is an electric charge in a stationary state. and the creation of static electricity, any matter is composed of atoms, the basic structure of atoms are protons, neutrons and electrons. The scientists defined the proton as positively charged, the neutron was not charged, and the electrons were negative. Under normal conditions, the number of protons in an atom is the same as that of electrons, which is negatively balanced, so it is not electrically charged. However, due to external effects such as friction or the use of various energy such as kinetic energy, energy, heat, chemical energy and other forms of action will make the atoms of the positive and negative electricity imbalance. Popular Point said, daily life we do any action, will produce static electricity, for example, between the skin and clothing and clothing and clothing friction, it will produce static electricity.

Electrostatic generation is not visible to the naked eye, and the production process has never been interrupted. And the human body is the largest electrostatic carrier, usually with tens of thousands of volts of voltage, and in the dry season of autumn and winter, static electricity more easily accumulated in the human body, tens of thousands of volts of high-pressure electrostatic body itself has no feeling, once contact with metal and other conductive materials, will be instantaneous release, if the static release object is the motherboard on the electronic chip, Tens of thousands of volts of voltage will instantly breakdown electronic components, resulting in hardware damage.

The existence of static electricity, always affect people's lives, small to peacetime by electricity, large to cause serious disaster. and the semiconductor industry, with the development of the industry, electronic components of electrostatic response is increasingly sensitive, many electronic products are marked with the need for anti-static. So for those of us kicking people, in daily life, how to effectively prevent the static electricity to the computer hardware damage, I will introduce several methods.

How to effectively avoid the N-way of electrostatic

First, the computer chassis needs reliable grounding

Some users respond, hand contact to the computer chassis, there will be shock paralysis feeling, this is because the chassis does not have a good grounding, static accumulation in the chassis can not be released, for a long time, not only may damage computer hardware, but also to the safety of the human security poses a threat. So this requires users to use electricity must have ground, good grounding to reduce the accumulation of static electricity.

Second, indoor humidification

Static electricity in the environment under dry conditions the most easy to accumulate, so it is necessary to maintain the surrounding environment appropriate humidity, especially in the northern region in the autumn and winter season should use humidifier, to maintain a certain humidity indoor air, to prevent static electricity in the equipment, furniture and physical accumulation.

Third, do a good job of protection measures

When you touch any circuit in your computer during the use or maintenance process, the standard practice is to wear a wrist-proof sleeve. For the vast number of ordinary users, you can first touch the computer chassis metal casing to release the body of static electricity (the premise is that the circuit has indeed been grounded, otherwise it will not be able to release the role of static electricity). If you cannot confirm whether the circuit is grounded, you can also use the method of touching the pipe to release static electricity.

Four, the protection before the external equipment

When you plug in a USB or IEEE 1394 device, you should release the body's static electricity in advance according to the 3rd method, reducing the chance of damage to the equipment and accessories due to static electricity.

The purchase of lightning-proof equipment

In addition, nature is also one of the origin of static electricity, which lightning generated by the electric shock surge is also a kind of static electricity, more destructive than the human or environmental static electricity to the damage caused by the computer. Lightning generated by the electric shock surge mainly by the power line and signal line intrusion, computer damage, and to prevent such things happen, can be achieved through the following methods of lightning protection measures.

For lightning surge generated by static electricity, in addition to do a good job in the environment in addition to static electricity, hardware parts also need to have anti-static function. Double-sensitive EVO Series Lightning protection motherboard is a good choice, the motherboard for electrostatic and natural lightning surge on the computer damage, designed lightning protection anti-static circuit, the board-load Swap network isolation transformer chip and increase anti-static design rtl8111e chip effective protection of static electricity on the computer damage.

When the Lightning (high voltage current) occurs, if the network cable in the transmission of severe surge fluctuations, the first lightning protection wall will be analyzed and identified, and in the confirmation of the surge of the moment will be transported to the ground area (ground treatment). If there is still residual voltage and escape lightning, then the second lightning wall will be ready to take care of them (the second ground treatment) to ensure that the network card and other parts of the motherboard are not damaged by the surge.

Among them, the first lightning protection wall is the main board of the Swap series network isolation transformer chip. Swap Series Network isolation variable-voltage chip, in the network card port to lightning surge for the first block, will be analyzed and identified, and in the confirmation of the surge of the moment will be transported to the ground floor area.

If there is still residual voltage and escape Lightning, the second lightning protection wall, that is, to increase the anti-static design of the rtl8111e chip, will be ready to take care of them, to ensure that the network card and other parts of the motherboard is not damaged by the surge. RTL8111E chip electrostatic pressure rise to 80%, clear the remaining lightning surge.

In the external equipment, for the power line intrusion of electric shock surge, in addition to home power has a good grounding, but also can buy lightning protection. The role of lightning protection, when the current security value over the warning line, lightning protection will automatically power off, so as to protect the power equipment, but also can buy UPS voltage regulator, but this kind of things we ordinary users rarely used, common in the financial machine or Internet cafes computer.
