Roll to Roll Process

Roll-to-Roll (R2R) Process for Flexible Printed Circuits

Continuous, High-Throughput Flex Circuit Manufacturing for High-Volume Applications

The roll-to-roll (R2R) process enables flexible circuits to be manufactured in a continuous web format, delivering outstanding throughput, quality and cost-efficiency. PICA’s R2R technology supports long-length, high-volume production of flexible PCBs, wearables, sensor ribbons, and printed electronics with tight tolerances and reliability.

Why Choose Roll-to-Roll (R2R) Process?

High Production Throughput & Scalability – Continuous unwinding, processing and rewinding eliminates the start-/stop of panel processing and enables higher volume output.
Lower Cost Per Unit for Flexible Circuits – Web-based processing reduces waste and handling, lowering manufacturing cost for large-volume runs.
Exceptional Uniformity & Precision – Tight web tension control, alignment guides and continuous flow maintain high dimensional and process consistency.
Ideal for Length, Flexibility & Compact Form-Factors – Enables long runs of flexible circuits (ribbon, roll, tape) with minimal seams, less interconnect complexity.
Optimized for Modern Applications – Wearables, IoT ribbons, medical sensors, large-area flexible electronics benefit from R2R’s continuous nature.

Roll-to-Roll (R2R) Capabilities – Highlights

Web processing for flex circuits: imaging, plating, etching, drilling and finishing conducted while substrate remains on roll.
Tight process controls: web tension, alignment guides, unwind/rewind speed control, profile flatness.
Fine-line routing and substrate usage compatible with long web formats; support for tape-&-reel or singulated output from roll form.
Engineering support for roll-to-roll vs panel trade-offs, substrate selection, handling of long runs, and volume manufacturability.

Global Design & Manufacturing Support

PICA provides end-to-end support for roll-to-roll flexible circuit programs — from early design consultation and stack-up definition, through pilot R2R runs and high-volume production. Our global footprint ensures scalable supply, continuous process control, and full traceability for roll-based flexible circuit manufacturing.

Benefits of Roll-to-Roll Process

Continuous Flow = Higher Output
By eliminating discrete panel transitions, R2R processes boost throughput and make high-volume flexible circuit builds cost-effective.

Consistent Quality Across the Web
Continuous motion and advanced tension/alignment controls ensure each unit from the roll meets the same high standard.

Simplified, Streamlined Interconnects
Roll-based flex circuits reduce the need for segmentation, joining or wiring harnesses — simplifying assembly and improving reliability.

Cost-Efficient for High Volumes
Web-based production reduces waste, handling and cycle time — delivering lower cost per unit when scale matters.

Design Flexibility for Modern Products
R2R supports long-run, high-density, flexible circuits in wearable, medical, industrial and IoT systems with tight form factors and high production volumes.
