LED display manufacturer technicians often need to deal with various problems that occur during the use of LED display screens in their daily work. There are some problems that are easily overlooked, and the results are often time-consuming and laborious. Today, Ralink display comes to you to talk about an LED display that is easily overlooked, static electricity.
LED pays great attention to anti-static measures. The following are some explanations for static electricity and anti-static electricity:
1.1. Source of static electricity:
The main source of static electricity that affects the circuit is the human body, plastic products, and related equipment and equipment. Static power from the use environment has the following items:
1. Objects, materials, floors, work tables and chairs 3, work clothes, packaging containers 4, paint or waxed surfaces, organic and glass fiber materials.
5, cement floor, paint or waxed floor, plastic floor tiles or floor leather.
6, chemical fiber work clothes, non-conductive work shoes, clean cotton overalls.
7, plastic, packaging boxes, boxes, bags, plates, foam plastic liners.
2. Electrostatic discharge failure
Sudden failure and potential failure.
The static failure of more than 90 in the use environment is a potential failure, which is manifested in the weakening of the circuit's resistance to electrical overstress and shortened service life.
3. Anti-static measures
1. Train static-sensitive circuits with static electricity knowledge and related technologies.
2. Establish an anti-static work area in which anti-static flooring, anti-static worktables, anti-static grounding leads, and anti-static appliances are to be used, and the relative humidity should be controlled at 40 or more.
3. The harm caused by static electricity to electronic equipment may be released anywhere from the manufacturer to the field equipment. The hazard is caused by insufficient, effective training and equipment manipulation failure. LEDs are devices that are sensitive to static electricity. INGAN chips are generally considered "first place" susceptible to interference. And ALINGAPLEDSSHI "second place" or better.
4, ESD damaged devices can show dim, fuzzy, extinguished, short or low VF or VR. Devices that are damaged by ESD should not be confused with electronic overloads, such as: faulty current design or driving, chip mounting, wire shield grounding or encapsulation, or common ambient induced pressure.
5. ESD security and control procedures: Most ESD and EMD companies have very similar ESDs and have successfully implemented ESD controls, controls, and main programs for all devices. These programs are instruments that have been used to detect quality effects since ESD. The ISO-9000 certification also lists him as a normal control program.
4. Transportation and packaging
In daily operation, ESD-sensitive devices should always be stored in anti-static bags or containers. This includes detailed inventory, transportation and WIP. Prevention during transportation includes consumed fleets, boxes or other equipment, such as conductive wheels or draglines, which are grounded when transporting ESD equipment.
