The CNSMT PCBA Coating Machine is a PLC-controlled selective conformal coating system designed for SMT assembly lines. Featuring touch screen operation and automated functions, this machine ensures precise coating application with minimal operator intervention.

• PLC control with intuitive touch screen interface
• Fault detection with sound and light alarm system
• Continuous surface painting with automatic distance and width detection
• Stepper motor reciprocating coating with adjustable PCB offset
• Special aluminum alloy track and stainless steel transmission chain
• Fan-shaped spray valve with automatic lifting mechanism
• Automatic rubber valve soaking to prevent clogging
• Communication ports for online integration with other machines
• Separate paint container drums for easy maintenance
• Integrated exhaust gas collection and discharge system

The machine features programmatic parameter input through the touch screen interface. The forward and backward motion operates at 800mm/s with stepper motor and synchronous belt drive. The equipment includes built-in cleaning functions and lighting source for optimal operation visibility.
