High Precision Conformal Coating Machine Automatic UV Conformal PCB
/PCBA Glue Dispenser Automated SMT Coating Line Machine
The SMT (Surface Mount Technology) Coating Line Machine is an
essential piece of equipment used in the electronics manufacturing
industry for applying protective coatings to printed circuit boards
(PCBs). This process enhances the durability and reliability of
electronic components by providing moisture, dust, and chemical
resistance.
Working Principle:
1. Coating Preparation: The machine begins with the preparation of
the coating material, which can be a conformal coating or an
encapsulant. This material is typically applied in liquid form.
2. PCB Loading: The PCBs are securely loaded onto the conveyor
system of the coating line. Proper alignment is crucial to ensure
uniform coating.
3. Coating Application: The machine utilizes various application
methods, such as spray, dip, or selective coating. In spray
coating, a robotic arm or nozzle applies a fine mist of the coating
material evenly across the PCB surfaces. Dip coating involves
immersing the PCBs in the coating solution, while selective coating
applies the material only to specific areas.
4. Curing Process: After the coating is applied, the PCBs are moved
through a curing section where heat or UV light is used to solidify
the coating. This step ensures that the coating adheres properly
and provides the desired protective properties.
5. Quality Inspection: The coated PCBs undergo inspection to check
for uniformity and coverage. Advanced vision systems can identify
defects or inconsistencies in the coating.
