At present, UV moisture three proof paint is widely used in circuit board coating, which is conducive to improving the production efficiency of automated production lines and effectively improving product yield. In practical use, machine spraying, manual gluing, and other methods can be selected according to the process requirements and characteristics. Local or whole boards can be coated with glue, and then cured using UVLED curing equipment to achieve the three prevention effects. The main advantages are as follows:

1、 Environmental protection and safety

1. It does not contain volatile organic compounds and does not pollute the ambient air;

2. There are relatively few restrictions or prohibitions on the composition of the adhesive in environmental regulations, which comply with RoHS and environmental impact assessment standards;

3. Solvent-free, low flammability.

2、 Economical and cost saving

1. UV glue has a fast curing speed, which is beneficial for automated production lines and improves labor productivity;

2. After solidification, it can be tested and transported, saving space;

3. UVLED curing equipment is a cold light source that can cure at low temperatures, saving energy. For example, the energy required to produce 1g of light cured pressure-sensitive adhesive is only 1% of the corresponding water-based adhesive and 4% of solvent based adhesive. Can be used for materials that are not suitable for high-temperature curing, and the energy consumption of UV curing can be saved by 90% compared to heat cured resins;

4. Small size, occupying less land, and saving space;

5. UV adhesive coating only requires a very thin layer, saving usage and reducing costs;

6. Single component system, no need for mixing, convenient to use.

3、 Compatibility

1. For temperature, solvent, and moisture sensitive materials, they can be used;

2. The curing time and degree are adjustable, making the operation more intelligent and convenient;

3. Can be applied repeatedly and cured multiple times;

4. UVLED curing equipment can be easily installed on existing production lines without significant modifications;

5. Shadow areas that cannot be illuminated by UV light can undergo secondary moisture curing.
