In recent years, LED display technology is gradually taking shape in our country, and the wide range of applications become popular trend. However, most of the LED display manufacturer is not entirely the production of these products have a real ability to bring products to the LED display a hidden danger, as well as the impact on the market as a whole. How to standardize the production, how to produce a real sense of low attenuation, the long-life LED display products? This article from the LED display production of static electricity protection point of view, to discuss the process of harms and electrostatic protection methods.
Static electricity causes:

At the micro, according to the theory of atomic physics, electricity and neutral when the material balance of power in the state, because of different substances have electronic access to the electronic gains and losses, the loss of material so that the balance of power, the phenomenon of static electricity.

From a macro sense for two reasons: heat of friction between objects, to stimulate electronic transfer; contact between the object and have a separation of electron transfer; electromagnetic induction surface caused by the imbalance in the distribution charge; friction and the combined effect of electromagnetic induction.

Electrostatic voltage is made up of different types of material contact with each other and separated from arising. This effect is well-known friction electrification, the voltage generated by friction with each other depends on the characteristics of the material itself. As the LED screen in the actual production process of human primarily associated with the components of direct contact and indirect contact with static electricity. Therefore, in accordance with the characteristics of the industry we can do a number of specific measures to prevent static electricity.

LED display in the static electricity in the production process hazards

If any link in the production of anti-static ignored, it will cause electronic equipment to damage and even failure.

When semiconductor devices or put into a separate circuit, even in the absence of power, due to static electricity can also cause permanent damage to these devices. Well-known, LED semiconductor products, LED if two or more pin-pin between the medium-voltage components than the breakdown strength, it will cause damage to the components. Oxide layer thinner, and the LED driver IC for the greater sensitivity of static electricity, for example, the solder is not full, solder problems with the quality of their own, and so on, will have a serious leakage path, resulting in devastating damage.

Another failure was due to the temperature node of semiconductor silicon than the melting point (1415 ℃) which may arise out of. Electrostatic energy pulse of local produce local heating, resulting in a direct lamp and the breakdown of the IC fault. Even if the medium voltage lower than the breakdown voltage, such failure will occur. A classic example is, LED is composed of PN junction diodes, emitter and the breakdown between the base would dramatically reduce the current gain. LED driver circuit itself or in the middle of the IC by the impact of static electricity, or may not appear immediately functional damage, the potential damage by the elements typically used in the process will be shown, so the impact on the life of the display are Fatal.

LED static electricity in the production of protective measures

First, ground

Is grounded directly to electricity through wires connected to vent into the earth, which is anti-static measures in the most direct and effective, the grounding conductor is usually used method, we require the use of a tool for artificial earth, with ground anti-static wristband, and Ground surface, and so on.

(1) in the production process requires workers to wear electrostatic grounding bracelet. In particular, cut feet, plug-in, commissioning and after the welding process, prepare and monitor the quality of personnel must be at least once every two hours to do a bracelet static testing, well test record.

(2) in welding, electric iron as far as possible to adopt anti-static low temperature soldering iron and good-ground.

(3) in the assembly process, as far as possible the use of the grounding line of low-voltage direct current electric screwdriver (commonly known as power granted).
