What is Conformal Coating?

Conformal coating is a thin protective layer applied on the surface of PCBA to shield them from environmental influences such as moisture, dust and corrosion. This coating is typically applied using an automatic selective coating machine, which ensures high precision and repeatability.

Advantages of the C5 Automatic Selective Coating Machine

  • Flexibility: Equipped with 3 valves and a ±180° rotating head, the C5 is the most flexible machine in its class – perfect for high-mix production environments.

  • Adaptive Design: Thanks to the 35° tilt angle of the valves, the machine reaches hard-to-access areas and ensures precise, uniform conformal coating.

  • High Precision: The 4-axis motor (X, Y, Z & U) with ±25 µm repeatability guarantees accurate coating results, even for complex applications.

  • Material Capability: The C5 can apply up to three different materials simultaneously via three separate valves – ideal for high conformal coating requirements.

  • Smart Automation: Automatic dipping and purging reduce manual effort and ensure a clean and reliable coating process.

The One-Man-Operator (OMO) concept optimizes the entire coating process by drastically reducing manual labor. With a pallet return conveyor and automated handling, the entire line can be efficiently operated by just one person. This means fewer manual interventions, more automation, and consistently high quality. The system ensures continuous production without downtime and reduces the risk of human error – leading to significantly improved productivity.

Benefits of the One-Man-Operator Concept:

  • Reduced Labor Effort: Less staff required thanks to the fully automated process flow.

  • Increased Productivity: Automation boosts process efficiency and minimizes downtime.

  • Lower Defect Rates: Automation lowers the risk of errors and damage, enhancing production quality.

  • Cost Efficiency: Achieved through minimal manual input and optimized efficiency.
