LED display anti-static knowledge, how much do you know?
The company is located in:
LED display products in the performance parameters, many people are more concerned about the display color, brightness, chip, power supply, IC and other issues, but very few people concerned about the anti-static LED display performance. Static electricity on the impact of electronic products is great, and sometimes even fatal, the following source (www.leddisplayls.com) and we work together to explore the anti-static knowledge.
First, the source of static electricity: the impact of static electricity sources are mainly human body, plastic products and related equipment, including static electricity sources from the use of the environment, including objects, materials; flooring, work desks and chairs; uniforms, packaging containers; paint or wax Plastic, packaging, boxes, cases, bags, trays, foams, and so on; the surface of organic and fiberglass materials; cement floor, paint or waxing floor, plastic floor tiles or floor leather; chemical overalls, non-conductive work shoes, clean cotton overalls; Plastic liner.
Second, static discharge failure: sudden failure and potential failure. Electrostatic failure in the use of more than 90 for the potential failure, the performance of the circuit resistance to electrical stress weakened, shortened service life.
Third, the anti-static measures: the use of electrostatic sensitive circuit personnel static electricity knowledge and related technical training; the establishment of anti-static work area, the use of anti-static flooring in the area, anti-static table, anti-static grounding leads and anti-static appliances, And to control the relative humidity to 40 or more; 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. While ALINGAPLEDSSHI is "second best" or better; ESD-damaged devices can show dim, blurry, off, short or low VF or VR. ESD-damaged devices should not be confused with electronic overloads such as: Incorrect current design or drive, die attach, wire shield grounding or encapsulation, or normal ambient induced stress; ESD safety and control procedures: Most The ESD for E & E companies is very similar and has resulted in the successful implementation of ESD control, maneuvering and main program for the device. These procedures because ESD has been used to measure the quality of ancient instruments. ISO-9000 also listed him as a normal control procedures.
Transport and Packaging: ESD sensitive equipment should always be stored in anti-static bag or container during daily operation. This includes inventory inventory, shipping and WIP. Preventive transportation includes consumption of fleets, boxes, or other equipment such as conductive wheels or pull-downs, the delivery of ESD equipment is grounded; LED display is currently on the market the most widely used large-screen display products, because Belong to high-end display products, the production cost is relatively high, LED display manufacturers need to conduct anti-static knowledge of employees training, while the relative humidity control at 40 above, as much as possible to reduce LED display damage rate during transport.
Grasp the anti-static knowledge, help to improve the LED display product production efficiency, but also reduce the occurrence of safety incidents.
