ICT PCBA Conformal Coating Machine

A conformal coating machine is an industrial device used in electronics manufacturing to automatically apply a protective conformal coating to printed circuit boards (PCBs). This coating shields 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 crucial for quality and reliability in series production.

Transport system
Transfers the PCBs through the machine (inline or stand-alone).

Coating application
Depending on the configuration:

- Spray coating (selective or full)
- Jet coating
- Film or atomization technique

XYZ positioning and motion system
Ensures precise control of the spray valve.

Vision and camera system (optional)
For alignment, inspection, and process control.

Masking / Selective coating
Protects connectors, test points, and other zones that should not be coated.

Drying or curing module
For UV, thermal, or air curing, depending on the coating material.

Control software
Programmable for different PCB designs and recipes.

Suitable coatings

- Acrylic
- Polyurethane
- Silicone
- Epoxy
