How to silicone potting for the LED driver?

 

In order to make the LED drive power supply waterproof, we generally seal the electronic components by filling glue. The glued material is generally made of silica gel and epoxy resin. Silicone is cheap, has good air tightness, strong adhesion and high hardness. But it is easy to turn yellow and not tolerate temperature. Epoxy resin is resistant to high temperature, can be reflowed, is not easy to yellow, and has stable performance. However, it has strong water permeability, low hardness and high price. We should choose different materials for different types of customers.

 

 

 

So  How to silicone potting for the LED driver?

 

 

 

Led drive power potting glue 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 how to use LED driver power encapsulants.

 

 

 

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 glue 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.
