1. Sudden damage will seriously reduce the yield of the product, thereby increasing the production cost of the product, sudden damage means that led products and components of the voltage between two or more pins than the medium can withstand the components The breakdown strength, function may be completely lost. This kind of damage is generally found in the production of quality inspection, and will not directly affect the customer, which will increase the cost of production.
2. Potential damage will reduce the service life of the product, causing serious damage to the customer. The potential damage is very high in the proportion of damage caused by electrostatic discharge, reaching more than 90%, and Lamp breakdown due to classical pulse energy causes lamp breakdown in ic testing is not easy to find. This makes the product will become very unstable, in the customer's use of the phenomenon of the phenomenon of the death will occur one after another, greatly affecting the life of the led display, resulting in loss to customers.
