OMO – One-Man-Operator Concept

OMO – One-Man-Operator Concept

The One-Man-Operator (OMO) concept is an innovative approach to significantly boost the efficiency and productivity of your conformal coating line. With just one operator and a fully automated pallet return system, manual workload is greatly reduced, while production quality and process consistency are significantly improved.

This concept is ideal for high-throughput SMT manufacturing and offers a cost-efficient solution to lower production costs and reduce material consumption.

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.

Why a Modern Coating Line Improves Your SMT Production

Conformal coating extends the lifespan of PCBAs and improves reliability. In SMT production, automated coating machines enable consistent and uniform coatings, ensuring higher product quality and fewer production failures.

One-Man-Operator Concept: The Key to Coating Line Automation

The One-Man-Operator Concept (OMO) optimizes production flow through automation. With an automatic pallet return system and minimal personnel requirements, coating lines can be operated more efficiently and cost-effectively. This concept requires only one operator and significantly reduces the need for human resources, while simultaneously boosting productivity and quality.

Coating Line Workflow with the OMO Concept

The One-Man-Operator Concept (OMO) revolutionizes SMT conformal coating lines by automating and simplifying the entire production process. Labor effort is drastically reduced, as only one operator is needed to monitor the complete process. The OMO concept enables continuous production and ensures higher quality and efficiency. Below is an explanation of the process step by step:

  • SMT Conveyor
    The SMT conveyor transports the PCBA throughout the entire coating process between the machines. First, the PCBA are moved into the C Series Conformal Coating Machine, where they are precisely coated with a protective film that shields them from environmental influences such as humidity, dust, and chemicals. Then, the conveyor transfers the PCBA to the jCURE+ Series Infrared Ovens or jCURE-2UV+ Ultraviolet Curing Ovens, where the coating is cured. Finally, the PCBA are transported to the inspection system to verify coating quality.

  • Coating Process
    Inside the C Series Conformal Coating Machine, a precise protective coating is applied on the PCBA. These machines ensure maximum accuracy and consistency during application. After the coating step, the PCBA is transferred to the curing oven for hardening. This ensures that the coating is fully fixed and stabilized for the following process steps.

  • PCBA Conformal Coating Lift
    After the coating and curing process, the PCBA Conformal Coating Lift transfers the PCBA to the lower level and returns to the conveyor at the beginning of the line, enabling further production. This vertical transport is crucial for maintaining the production flow without manual intervention.

  • End of the Cycle
    After quality inspection and completion of the coating process, the return conveyor brings the PCBA back to the start of the line. This allows the operator to remove finished PCBA or forward it directly to the next production step. The return conveyor minimizes the need for manual handling and reduces production interruptions.

Advantages of the One-Man-Operator Concept:

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

  • Increased Productivity: Higher throughput and less manual handling lead to faster production cycles.

  • Lower Costs: Achieved through minimal manual input and optimized efficiency.

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

  • Better Consistency: Every production cycle delivers precise and repeatable results.

OMO Half Line vs Full Line

OMO Half Line for SMT conformal coating with 10 to 15 pallets for small to mid-size production volumes
Fully automated OMO Full Line for SMT conformal coating with 25 to 30 pallets

The OMO Half Line, with 10 to 15 pallets, provides an ideal solution for small to medium production volumes. It enables high flexibility with lower initial investment.
The OMO Full Line accommodates 25 to 30 pallets and is designed for large-scale production environments where capacity and efficiency need to be fully maximized. Both options offer clear cost advantages and improved quality.
