How do I brush coat my conformal coating?

The application of a conformal coating using a brush to “paint” on the material to the circuit board is a common practice all over the world.

Generally, it is done as a final touch up process after the main application method is used.

However, it can also be done in mainstream production.

Applying the conformal coating

The operator according to the requirements of the circuit board applies the conformal coating selectively with the brush.

Areas not be coated are avoided.

The key for success with brushing conformal coating is the technique of application.

The correct method is to flow the coating on. The coating should be loaded on to the brush and flowed onto the circuit.

The material should not be brushed on like paint.
