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.
LED drive power potting adhesive is suitable for potting protection of general electronic components, power modules and circuit boards, as well as potting of various electronic appliances, such as switching power supplies, drive power supplies, automotive HID lamp module power supplies china, automotive ignition system module power supplies Vdwall A6000, Appliance controller, network transformer, etc. Many customers do not understand the use of LED sign parts. Now I will explain the use of LED driving power potting glue.
