Many newcomers to the LED display are curious why they are required to wear protective equipment such as shoe covers, static rings and static clothing when visiting many LED display shops. To understand this issue, it is necessary to mention the production of LED display in the protection of static electricity related knowledge; a lot of LED display appears dead or not bright, mostly due to static electricity. LED display during the production of static electricity source 1, objects, materials 2, the floor, work tables and chairs 3, overalls, packaging containers; 4, paint or waxed surfaces, organic and fiberglass materials. 5, cement floor, paint or waxing floor, plastic floor tiles or floor leather. 6, chemical fiber clothes, non-conductive electrical work shoes, clean cotton overalls. 7, plastic, boxes, boxes, bags, plates, foam pads. The dangers of static electricity in the LED display production process If any part of the production of anti-static neglected, it will cause the electronic equipment failure or even damage it. When a semiconductor device is placed alone or into a circuit, permanent damage to these devices can be caused by static electricity even if power is not applied. It is well-known that LEDs are semiconductor products that can damage components if the voltage between two or more pins of the LED exceeds the breakdown strength of the component media. The thinner the oxide layer, the more sensitive the LED and the driver IC are to the static electricity. For example, the solder is not full, the quality of the solder itself is a problem, and so on, which causes a serious leakage path and causes destructive destruction. Another failure is due to node temperature exceeds the melting point of semiconductor silicon (1415 ℃) caused. Electrostatic pulse energy can generate local heating, resulting in breakdown of the lamp and the IC directly. This failure can occur even if the voltage is lower than the breakdown voltage of the medium. A typical example is that LEDs are diodes made of PN junctions and the breakdown of the emitter and base causes the current gain to drop dramatically. The LEDs themselves or the ICs in the driver circuit may not exhibit functional damage immediately after being affected by static electricity. The potentially damaged components are usually not shown during use, so the lifetime of LED products It is fatal. LED display production process is a very rigorous, subtle process, each link can not be overlooked. Display ESD protection work is also an important part of LED display production, the current industry awareness of ESD protection is not enough profound, but can not meet the needs of professional LED display production, but also need more professionals continue to study and work together discuss. LED display in the production of anti-static: 1) Electrostatically sensitive circuit personnel using static electricity knowledge and related technology training. 2) The establishment of anti-static work area, the use of static electricity in the area of ​​the floor, anti-static workbench, anti-static grounding leads and anti-static appliances, and the relative humidity to 40 or more. 3) The harm caused by static electricity to the electronic equipment may be released anywhere from the manufacturer to the field equipment. Hazards are caused by inadequate and effective training and equipment failure. LED is static-sensitive equipment. INGAN chips are generally considered "first place" susceptible to interference. And ALINGAPLEDSSHI "second" or better. 4) The ESD-damaged device can show dim, blurry, extinguished, short or low VF or VR. Devices damaged by ESD should not be confused with electronic overloads such as incorrect current designs or drivers, die attach, wire shield grounding or packaging, or normal ambient induced pressure. 5) ESD Safety and Control Procedures: Most E & E companies have very similar ESD and have successfully implemented all of their ESD control, maneuvering, and main program. These procedures because ESD has been used to measure the quality of ancient instruments. ISO-9000 certification also put him in the normal control procedures.
