LED driver power potting use
LED drive power potting adhesive for general electronic components, power modules and circuit board potting protection, and a variety of electronic potting, such as switching power supply, drive power, automotive HID lamp module power supply, ignition system module power , Home appliances, network transformers and so on. Many customers do not understand the use of LED driver power potting agent, Xin Wei Xiaobian now for everyone to explain about the use of LED driver power potting:
1, before mixing: A, B components were first manually or mechanically mixed thoroughly, to avoid filling due to settlement caused by changes in performance.
2, mixed: according to the ratio of 1: 1 weighing two components into a clean container stir, the error can not exceed 3%, otherwise it will affect the performance after curing.
3, defoaming: Natural defoaming: The mixed gel is allowed to stand for 20-30 minutes, vacuum degassing: a vacuum degree of 0.08-0.1MPa, vacuum 5-10 minutes.
4, perfusion: the rubber should be completed within the operating time perfusion, or affect the level. Pre-encapsulation substrate surface to keep clean and dry.
5, curing: curing at room temperature or heat can be. Glue curing speed and curing temperature have a great relationship, in the winter takes a long time to cure, it is recommended to use heating curing, curing at 80 ℃ for 15-30 minutes, usually 6-8 hours at room temperature curing conditions.
