Insulating Varnish application
This sealing process can be done by means of potting, casting, or encapsulation. These names are used interchangeably, which can lead to term confusion. The terms most commonly used are pot and encapsulation. Common industry definitions are:
- Pot - The pot method uses a container (pot) to load the device and then it is filled with a liquid pot. The case becomes part of the unit. This is the method most frequently used, especially for high production conditions.
- Casting - Casting is basically the same as pot making but the mold box is removed after encapsulation and drying.
- Encapsulation - Encapsulation also refers to the device being immersed in resin and a thick layer enveloping the unit. This method is often referred to as "dip coating".
