1. Sudden damage will seriously reduce the product yield, thereby increasing the production cost of the product, the meaning of sudden damage is led product components between the two or more pin voltage exceeds the component medium can withstand The breakdown strength, the function may be completely lost. This kind of damage is generally able to be produced in the time, through the quality of detection found, and will not directly affect the customer, which will increase the cost of production.
2. Potential damage will reduce the life of the product, resulting in serious losses to the customer, the potential damage in the electrostatic discharge damage in the proportion is very high, has reached more than 90 percent, and Due to the classic pulse energy caused by lamp heating caused by lamp breakdown in the ic test is very easy to be found. Which makes the product will become very unstable, the follow-up in the process of the use of the phenomenon of dead lights will occur one after another, a great impact on the life of the led display, so as to bring losses to customers.
