Single layer flexible circuits are found in countless applications across industries.
LED strips, backlighting modules, and decorative lighting use single layer flex PCBs for their combination of low cost and flexibility. Simple trace routing connects LEDs in series or parallel configurations.
Temperature sensors, capacitive touch sensors, and other sensor arrays use single layer flex to connect sensing elements while conforming to product shapes.
Battery pack interconnects and protection circuits use single layer flex for reliable connections in the constrained space of battery assemblies.
Simple interconnects in consumer devices, from button panels to display connectors, benefit from single layer flex's cost-effectiveness.
Single-use medical devices like ECG electrodes and glucose sensor strips use single layer flex for economical high-volume production.
Designing single layer flex PCBs requires attention to the unique aspects of single-sided construction.
With only one conductive layer, all traces must be routed without crossovers. Careful planning of trace paths is essential for complex designs.
When crossings are unavoidable, jumper wires or zero-ohm resistors can bridge traces. We can integrate jumpers into the manufacturing process.
Solid ground planes can be implemented on a single layer, but signal and ground traces must share the same layer. Consider split ground strategies for noise-sensitive designs.
Components can be placed on either side of the circuit, but all pads must connect to the single trace layer. Design for access from both sides if required.
Single layer construction offers the best bend performance. Keep traces perpendicular to bend lines and avoid components in dynamic flex areas.
Single layer flex PCB manufacturing is streamlined for efficiency and cost-effectiveness.
Polyimide offers the best combination of flexibility, temperature resistance, and reliability. PET and PEN provide lower-cost alternatives for less demanding applications.
Rolled annealed copper provides superior flexibility for dynamic applications. Electrodeposited copper is cost-effective for static flex uses.
Polyimide coverlay provides the best protection and flexibility. Flexible solder mask is a lower-cost alternative for less demanding applications.
FR4, polyimide, or metal stiffeners can be added to connector areas and component mounting zones for mechanical support.
ENIG provides excellent solderability and corrosion resistance. OSP and immersion tin are cost-effective options for high-volume production.

Medical grade single layer flex for disposable ECG patches. Biocompatible materials with conductive traces for skin contact electrodes.
Ultra-thin single layer flex connecting side buttons to main board. 0.1mm total thickness with fine-pitch ZIF connector.
Single layer flex is our most economical option. Prototype pricing starts from competitive rates with volume discounts available. Request a quote with your specifications for accurate pricing.
Our fastest prototype service delivers single layer flex in 3-5 business days. Standard prototype service is 5-7 days. High-volume production lead times depend on quantity.
Yes, components can be mounted on either side, but all electrical connections must be on the single conductive layer. Access holes through the base material can provide soldering access from both sides.
Our thinnest single layer construction is approximately 0.05mm (50 microns) total thickness using thin polyimide and copper. Typical constructions range from 0.1mm to 0.2mm.
Single layer flex offers the best dynamic flex performance due to its thin construction. With proper design attention to bend radius and trace routing, single layer circuits can withstand millions of flex cycles.
