Product Overview Our Exposed Flex Circuits feature flexible printed circuit boards manufactured without a protective cover layer (coverlay), providing direct access to conductor traces and component pads. These specialized flex PCBs offer enhanced flexibility, reduced thickness, and cost-effective solutions for applications where environmental protection is not critical.
Key Features
- Ultra-thin profile – Eliminates coverlay thickness for maximum flexibility and bend radius
- Direct trace access – Allows for easy probing, testing, and component attachment
- Superior flexibility – Enhanced bend performance with reduced stiffness
- Cost-effective design – Lower manufacturing costs compared to covered flex circuits
- Lightweight construction – Minimal material usage for weight-sensitive applications
- Excellent signal integrity – Reduced dielectric thickness improves electrical performance
Technical Specifications
- Base materials: Polyimide (PI) or PET substrates
- Copper weights: 0.5oz to 2oz (17.5ฮผm to 70ฮผm)
- Minimum trace width: 0.1mm (4 mil)
- Thickness range: 0.05mm to 0.2mm
- Operating temperature: -40ยฐC to +150ยฐC (polyimide base)

Ideal Applications
- Internal device connections where protection isn’t required
- Temporary test fixtures and prototyping
- Weight-critical aerospace and automotive applications
- High-frequency RF circuits requiring minimal dielectric
- Cost-sensitive consumer electronics
- Sensor arrays and wearable devices
- Battery connections and power distribution
Manufacturing Advantages
- Faster production turnaround
- Reduced material costs
- Simplified assembly process
- Enhanced thermal dissipation
- Improved impedance control
Design Considerations While exposed flex circuits offer numerous benefits, they require careful handling during assembly and are best suited for protected environments or internal applications where mechanical stress and contamination are minimal.
