ICT PCBA Conformal Coating Machine

A conformal coating machine is an industrial system used in electronics manufacturing for the automated application of a protective conformal coating to printed circuit boards (PCBs). This coating serves to safeguard sensitive electronics from external factors such as moisture, dust, chemicals, corrosion, and temperature fluctuations.

The machine applies a thin, uniform protective layer to selected areas of the PCB. This process is fully automated and repeatable, which is essential for quality and reliability in mass production.

Transport System
Conveys PCBs through the machine, available as inline or stand-alone configurations.

Coating Application
Depending on the design:

- Spray coating (selective or complete)
- Jet coating
- Film or atomization techniques

XYZ Positioning and Motion System
Enables precise control of the dispensing valve.
