Power Supply factory potting glue use method

Power Supply factory 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 supply, driving power supply, automotive HID lamp module power supply, automotive ignition system module power supply. , home appliance controllers, network transformers, etc. Many customers do not understand the use of LED driver power potting glue. Now, we explain how to use LED driver power potting glue:

1. Before mixing: A and B components should be fully stirred manually or mechanically to avoid performance changes due to sedimentation of the filler.

2. Mixing: Weigh the two parts in a 1:1 ratio and put them into a clean container and mix well. The error should not exceed 3%, otherwise it will affect the performance after curing.

3. Defoaming: Natural defoaming: The uniformly mixed gel is allowed to stand for 20-30 minutes, vacuum defoaming: vacuum degree is 0.08-0.1 MPa, vacuum is taken for 5-10 minutes.

4, perfusion: the glue should be filled in the operation time, otherwise it will affect the leveling. The surface of the substrate is kept clean and dry 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 ° C for 15-30 minutes, and it usually takes about 6-8 hours to cure at room temperature.
