Polymer liquid silicone: protective shield for circuit boards

    With the rapid development of science and technology, various electronic products are increasingly updated. As the core component of electronic products, the performance and stability of the circuit board are very important to the whole product. Silicone polymer liquid Silicone Rubber (LSR) is the 1 kind of polymer synthetic material with high elasticity, high temperature resistance and chemical corrosion resistance.

 What are the applications of polymer liquid silica gel on the circuit board?

1. Packaging and protection: Liquid silicone can be used as the 1 packaging material to completely wrap the circuit board in it to form a sealed protective layer. This can effectively prevent the circuit board from being affected by the external environment, such as moisture, dust, salt spray, etc., thereby improving the stability and service life of the circuit board. At the same time, liquid silica gel also has good thermal conductivity, which can help the circuit board to dissipate heat, reduce the working temperature, and improve the working reliability of electronic components.

2. Filling reinforcement: In the process of making the circuit board, some parts may have voids or unevenness. At this time, liquid silica gel can be used for filling, so that the surface of the circuit board is more flat, and the strength of the circuit board is increased to prevent damage caused by external force. In addition, liquid silica gel can also be used to fill through holes, gaps, etc. on the circuit board to improve the sealing performance of the circuit board and prevent gas or liquid from entering, causing short circuits or other failures.

3. Insulation and isolation: Liquid silica gel has good insulation properties and can be used as the 1 insulation material for insulation and isolation on circuit boards. For example, in a multi-layer circuit board, the wires of different layers can be separated by liquid silicone to prevent current leakage or short circuits. At the same time, liquid silicone can also be used to protect sensitive components on the circuit board, such as sensors, chips, etc., to prevent static electricity, electromagnetic interference and other damage to it.

4. Seismic buffer: Because liquid silicone has good flexibility and elasticity, it can be used as the 1 seismic buffer material for the seismic design of circuit boards. When an electronic product is impacted by an external force, the liquid silicone can absorb part of the impact, reduce the impact on the circuit board and electronic components, and improve the anti-drop and durability of the product.
