Process · Conformal Coating
Selective conformal-coating systems
Selective conformal coating applies coating material precisely to electronic assemblies. Connectors, contacts and other keep-out zones can be accounted for in the coating program.
How conformal coating works.
Spray and needle valves follow programmed contours. Camera-assisted teaching and DXF or image data support setup. For repeatable results, material, viscosity, valve, target coating thickness and component geometry must be matched.
Typical application
The SC-902 is a benchtop system with two work platforms. The inline SC-903R and SC-904 transport PCBs through the process; the SC-904 has four standard valves.
What matters when choosing a system.
Coating area
Check format and component height. With two work platforms, the stated areas apply to each platform.
Keep-out areas
Check connectors, test points and contact surfaces in the program and on samples.
Valves and material
Narrow spray and needle valves are standard equipment; additional valves are model-dependent options.
Inspection after coating
The CI-900 is a separate inspection system for optical coating inspection.

What data is needed for system design?
PCB format, component heights, coating material, target areas, keep-out zones and inspection objectives.
Is optical inspection integrated?
The CI-900 is a separate system. Whether and how it is integrated into the line depends on the project.
