It is very important to choose UV three glue suitable for flexible FPC plates. The FPC board, or the flexible printed circuit board, is a flexible substrate, often used in electronic products that need to bend or zigzag. The UV three-proof glue is a special glue used to protect the surface of the circuit board, with the function of waterproof, dustproof and corrosion prevention. Choosing ENIENT EG2504 can not only improve the service life of the FPC board, but also ensure the stability of the circuit board.

 So, what kind of UV three-proof glue to use for the flexible FPC board? The following are the key factors for selecting the three-proof glue:

1. High-temperature resistance performance
Because flexible FPC plates are often used in high temperature environment, the high temperature resistance of UV three-proof adhesive is very important. The selection of high temperature resistant three-proof glue can ensure that the circuit board in the high temperature environment will not be soft, glue off, to ensure the normal work of the circuit.

2. Chemical resistance
Electronic products often need to work in the environment of various chemicals, so the chemical resistance of UV three-proof glue is also an important consideration. Choosing the-proof glue with good chemical resistance can prevent the corrosion of the surface of the circuit board and prolong the service life of the circuit board.

3. Flexibility
The flexible FPC board itself is flexible, so choosing a flexible UV three-proof adhesive can maintain the flexible characteristics of the circuit board and avoid the decline of the bending performance of the FPC board due to the hardening of the glue.

4. Resistant performance
Electronic products often need to be used outdoors or in a humid environment, so the weather resistance of UV three-proof rubber is also an important consideration. The glue with good weather resistance can ensure that the circuit board is not affected by moisture and improve the stability and reliability of the circuit board.

 When choosing the UV three-proof glue of the flexible FPC board, the above several factors need to be considered comprehensively. In addition, according to the actual use environment and requirements, you can also choose three proof glue with special functions, such as good UV resistance for outdoor products, good wear resistance for electronic products often subject to friction.

 In conclusion, the key factors such as high temperature resistance, chemical resistance, flexibility and weather resistance should be considered in selecting the flexible FPC board to ensure the stability and reliability of the circuit board. Customers should ask for the relevant technical information from the manufacturer, compare and test in various aspects, in order to choose the most suitable for their products UV three prevention glue.
