What is a contactless dipensing valve and how does it work with my selective robotic conformal coating system?
As the name implies, these valves typically operate between 2-10mm from the surface onto which they are dispensing and can apply very small dots or well defined lines and can be used to coat critical areas or discrete components. These types of valves generally work best with materials with some degree of thixotropy and medium apparent viscosities. These valves do rely on unhindered access to the coating area and are most suitable for SMT technology.
