The Reason And Countermeasure Of False Death Of Digital LED Flexible Strip

The Reason and Countermeasure of False Death of Digital LED Flexible Strip
Digital LED Flexible Strip bar in the production process will appear LED suspended animation phenomenon (that is, LED does not shine), this phenomenon in the 5050 Digital LED Flexible Strip bar most likely to appear, and now still show the photo to explain the cause of this phenomenon and the corresponding Countermeasures, hope to increase the Friends of the Digital LED Flexible Strip understanding of the article.
Cause 1: Electrostatic burnout
Because the LED is an electrostatic sensitive components, therefore, if the production process for the electrostatic protection work is not done, it will burn the LED chip because of static electricity, resulting in Digital LED Flexible Strip footage phenomenon.
Countermeasures: to strengthen the electrostatic protection, any contact with the LED staff, must be in accordance with the provisions of wearing anti-static gloves, static ring, tools and equipment must be grounded.
Cause 2: High temperature is damaged. LED high temperature performance is not good, so if the production and maintenance process for the LED welding temperature and welding time is not controlled, it will be because of high temperature or sustained high temperature caused by LED chip damage, resulting in Digital LED Flexible Strip The phenomenon of suspended animation.
Countermeasures: good reflow soldering and soldering iron temperature control, the implementation of personal responsibility, special file management; soldering iron using temperature control soldering iron, effectively prevent the high temperature burned LED chip.
Cause 3: Moisture bursts at high temperatures. LED packaging if the long-term exposure to moisture in the air will be, if not dehumidified before use, in the reflow soldering will be because the reflow in the temperature is too high, the time period is long and lead to the LED package of moisture heated, LED package burst, which led to LED chip overheating and damage.
Countermeasures: LED storage environment to constant temperature and humidity, unused LED before the next use must be placed in about 80 ° oven baking 6 to 8 hours for dehumidification treatment to ensure that the use of LED will not have suction Tide phenomenon.
    High-quality products not only have high-quality raw materials, but also to have a standardized process operation and professional protection measures, Shang Ming photoelectric is the details of the implementation to the implementation of the product quality to achieve the ultimate industry model.
Now, the Digital LED Flexible Strip bar is already a lot of family or business use of a lamp, because it is widely used, has been involved in many areas, is currently used in the production of lamps used in the most extensive. Today is still bright photoelectric-shinmi give you a talk about what is the use of Digital LED Flexible Strip bar. For which areas.
  First of all, we are most familiar with the home: Digital LED Flexible Strip bar is the rise in recent years, a kind of lighting, the first is used for home lighting. Many people buy home are installed in the ceiling of the sandwich or the interior of the wall skirt, because now the Digital LED Flexible Strip strip is a lot of colors can be used to control the official, so play the role of environmental protection, Do more than just watch it.
   Stage lighting: in some performances, we will often see the Digital LED Flexible Strip strip used in the figure, because of its low price has a good effect on the stage, so now many of the stage performances, will use the Digital LED Flexible Strip bar as Part of the stage lights. Is a new way of using it.
