Conformal Coating Dipping with silicones operating procedure

When using silicone conformal coatings with conformal coating dip systems there are several rules that are worth understanding. At the end of a shift you should:

1. Turn off the  pump

2. If you are using a solvent-based moisture-cure material, carefully  pour solvent over the top of the coating, so that the  solvent floats on the coating.

3. Place the lid on the tank and purge with dry air, nitrogen or argon for a short time.

4. Run the air purge continuously to keep positive pressure inside the tank.

Conformal Coating Dipping using solvent-free, water based conformal coating materials

Using waterbased conformal coatings like Humiseal 1H20 AR1 in conformal coating dip systems is easy with a few modifications. Using the water based conformal coatings eliminates solvents and gives a very stable process.

Conformal coatings – Dipping Horizontally

It is prefectly fine to dip printed circuit boards horizontally into conformal coating and achieve the same excellent results.

However, the important factors are conformal coating viscosity, dry time, tank design, accuracy of dip depth and drain angle which will ultimately determine how success the proces is.

Conformal Coating and Dipping.

Automatic Dip Coating is one of the most efficient methods for application of conformal coatings and is excellent for all volume production whether large or small.

The process of dipping a circuit boards into a conformal coating material contained in a tank ensures complete coverage, including underneath components and around difficult large 3D boards and as an advantage there is no over spray or material wastage.

Conformal Coating Dip Systems – Viscosity Control

There are two methods for controlling viscosity with conformal coating materials and dip coating applications.

The first is flow cup control which is a manual process. A cup of known size with a hole in the centre is filled with the conformal coating and the time for the material to run out is related to viscosity. This is reasonably accurate and normally is suitable for most applications.

An alternative is inline viscosity control of the conformal coating where the solvent evaporation and material top up is controlled by a viscometer and plc controlled system. This is extremely accurate and removes all of the manual processes involved in testing with a flow cup.
