Dispensing, or filling, is the discharge of low-viscosity material into a substrate, such as e.g. a component housing.

 
Filling is used when sensitive electronic components must be protected from external chemical, corrosive or mechanical influences. The dispensing media used for filling are the so-called low-viscosity casting resins based on polyurethane, silicone or epoxy.


The goal is to extend the assembly’s service life and to optimise its functionality.


 Conformal Coating: Instead of filling, conformal coating is often used to cover a surface with a thin layer of casting resin. This dispensing variant not only protects the element from external influences, but also increases the stability of delicate assembly parts.
