Client Requirement
A global medical equipment manufacturer required a reliable electronic control system for a dental surgical light, designed to deliver consistent illumination during procedures.
The system needed to provide precise control over light intensity and integrate seamlessly within a compact surgical setup, ensuring usability in continuous clinical environments.
The Challenge
In surgical lighting applications, precision and consistency are critical.
The client required a solution that could:
- Enable accurate control of light intensity and focus
- Integrate electronics within a compact and ergonomic form factor
- Ensure reliable operation in continuous-use medical environments
- Support efficient validation to enable production scaling
Additionally, the design involved rigid-flex PCB implementation, increasing complexity in both integration and testing.
The Solution
Aimtron developed a tailored electronics solution combining control systems, power management, and manufacturability.
Touch-Based Control System
A touch-sense controller was developed to enable intuitive and precise adjustment of lighting intensity.
Constant Current LED Driver
A dedicated LED driver ensured stable illumination output, maintaining consistent light performance during operation.
Rigid-Flex PCB Design
The system was engineered using a combination of rigid and flexible PCBs, enabling compact integration within the surgical assembly.
Test Engineering Optimization
A custom test fixture was developed to validate multiple boards simultaneously, significantly improving testing efficiency.
Implementation Highlights
