What are the coating methods of PCB circuit board coated with conformal coating?

The conformal coating operation methods can be divided into brush coating method, dip coating method, spray method and spray coating method

The conformal coating operation methods can be divided into brush coating method, dip coating method, spray method and spray coating method:

1. Brush method is the easiest coating method. It is usually used for local brushing, repair and maintenance, and can also be used in laboratory environments or small batch trial/production, generally in occasions where the coating quality requirements are not very high.

2. Dip coating method is widely used, suitable for completely coated occasions; In terms of coating effect, dip coating method is one of the most effective methods.

3. Spraying method is the most commonly used coating method in the three anti-paint industry, which is divided into two kinds: machine automatic spraying and manual spraying.

① Manual spraying investment is small, easy to operate; Sharp coating has a spray type three anti-paint, simple and easy to operate, direct spraying.

② The coating consistency of machine automatic spraying is better, the production efficiency is the highest, and it is easy to achieve online automatic production, which can be suitable for large and medium batch production.

4. The shower coating method is a coating method that is not recommended by the conformal coating manufacturers.
