What are the three anti-paint processes?

Three-proof paint is also called electronic circuit board protective oil, coating oil, waterproof glue, insulating paint, moisture-proof paint, three-proof paint, anti-corrosion paint, salt spray paint, dust-proof paint, protective paint, coating paint, three-proof Glue, electric anti-glue, etc. The electronic circuit boards that have used the three-proof paint have the performance of waterproof, moisture-proof, dust-proof "three-proof" and resistance to cold and heat shock, aging resistance, radiation resistance, salt spray resistance, ozone corrosion resistance, vibration resistance, vulcanization resistance, and good flexibility , Strong adhesion and other properties. In order to make the three anti-paints better play their excellent performance, the operation process is a very important link. Many users always feel that they have not achieved the excellent protection effect they imagined when using the three-proof paint. In fact, a large part of the reason is that the operation process of the three-proof paint is not used correctly. All, in order to better achieve the protective effect of the three-proof paint , It is necessary for the user to understand the use process of the three-proof paint.
The three anti-paint use processes mainly include the following four:

1. Brushing: manual operation, generally simple and convenient to use, can produce a good smearing effect on a smooth surface
2. Spraying: The spray can type products can be easily applied to maintenance and small-scale production. The spray gun is suitable for large-scale production, but these two spraying methods require high accuracy of operation and may produce Shadow (the place where the lower part of the component is not coated with three anti-paint);
3. Dip coating: Dip coating can ensure complete film coating and will not cause material waste due to overspray;
4. Equipment selective coating: The coating is accurate and does not waste materials. It is suitable for mass coating, but it has higher requirements for coating equipment and is most suitable for mass production of circuit board coating.
