Conformal Coater
PCBA Conformal Coating Machine
The PCBA Conformal Coating Machine is an automated system for selective conformal coating of printed circuit board assemblies. It is designed to apply coatings accurately and repeatably using servo-driven XYZ motion and a programmable coating path.
The machine supports multiple coating methods and materials and can be configured with different valve types depending on the application. Stable PCB transport, precise motion control, and fast program setup make it suitable for both prototype work and continuous production environments
