Engineering Risks & FAQ - **Caution**: - **Caution**: - **Caution**: ### Q: What is the typical cycle time for this PCB assembly line? **A**: The cycle time is 8–15 seconds per board for typical assemblies, depending on board complexity and component count. This is a reference range; actual cycle time must be confirmed with the manufacturer for specific configurations. ### Q: What is the maximum PCB size supported? **A**: The system supports PCBs up to 610×610 mm. This is a maximum dimension; larger boards may require custom configurations. Verify with the supplier for your specific board sizes. ### Q: What are the environmental requirements for operation? **A**: The recommended operating temperature is 15–35°C, and relative humidity should be 30–70% non-condensing. These conditions ensure optimal performance and reliability. Always follow the manufacturer's guidelines. ### Q: What ingress protection ratings are available? **A**: Control cabinets and motors are rated IP54–IP65 according to IEC 60529. This indicates protection against dust and water jets. Confirm the exact rating for each module with the manufacturer, as it may vary. ## 6.
