LED failure cannot be found in the regular inspection test of LED industry Novastar MCTRL660. Under severe conditions such as high temperature, low temperature, and rapid temperature changes, it is caused by the difference in thermal expansion coefficients of LED chips, epoxy resin, brackets, inner leads, die-bonding adhesives, PPA cups and other materials, resulting in different internal stresses. The mechanism of LED failure caused by electrostatic discharge is very complicated. Equipment, tools, utensils, and human bodies may carry static electricity and discharge it. This static electricity ranges from several hundred volts to tens of thousands of volts. The discharge time is in the nanosecond range Level.
