LED driver power supply potting for general electronic components, power modules and circuit board potting protection, and a variety of electronic appliances potting, such as switching power supply, drive power, car HID lamp module power, car ignition system module power , Home appliances control, network transformers and so on. Many customers do not understand the use of LED driver potting method, now by Xinwei Xiaobian for everyone to explain the use of LED driver on the use of potting method:
1, before mixing: A, B components were first manually or mechanically, respectively, to fully stir, to avoid the performance of the filler as a result of subsidence changes.
2, mixing: according to 1: 1 ratio of two components into a clean container into the mixing evenly, the error can not exceed 3%, otherwise it will affect the performance after curing.
3, defoaming: natural defoaming: the mixture will be mixed evenly for 20-30 minutes, vacuum defoaming: vacuum 0.08-0.1MPa, vacuum 5-10 minutes.
4, perfusion: should be in the operation time will be finished filling the compound, otherwise the impact of leveling. The substrate surface remains clean and dried before potting.
5, curing: room temperature or heat curing can be. The curing speed of the glue has a great relationship with the curing temperature. It takes a long time to cure in the winter. It is recommended to cure by heating. It is cured at 80 ℃ for 15-30 minutes. It is necessary to cure about 6-8 hours at room temperature.
