Flexible PCBs excel in applications requiring bending, folding, or fitting into tight spaces, while rigid PCBs are ideal for stable, high-component-density applications. Flex PCBs cost more upfront but can reduce overall assembly costs by eliminating connectors and cables. Choose flex for wearables, medical devices, and aerospace; choose rigid for consumer electronics, computers, and industrial equipment.
Best Choice
Depends on Application
Flexible PCBs are the ideal choice when your design requires dynamic movement, space optimization, or weight reduction. They're particularly valuable in applications where reliability under repeated flexing is critical.
Rigid PCBs remain the standard choice for most electronic applications where stability, high component density, and cost-effectiveness are priorities. They're easier to manufacture and repair.
While flex PCBs have higher per-unit costs, they can reduce total system costs significantly. A flex circuit can replace multiple rigid boards, connectors, and cables, simplifying assembly and improving reliability.
Rigid PCBs typically have shorter lead times due to standardized processes and wider manufacturing availability. Flex PCBs require specialized equipment and expertise, affecting delivery schedules.

Yes, but it requires design modifications. Flex PCBs have different design rules for trace routing, bend areas, and component placement. Our engineering team can help you adapt your design for flex manufacturing.
For dynamic applications with repeated bending, flex PCBs are more reliable as they're designed for movement. For static applications, both offer excellent reliability when properly designed.
The minimum bend radius depends on the number of layers and copper thickness. Generally, single-layer flex can bend to 6x the total thickness, while multilayer requires larger radii. Use our Bend Radius Calculator for specific guidance.
Yes, flex PCBs can be designed for high-frequency applications using appropriate materials like LCP (Liquid Crystal Polymer) or modified polyimide. Controlled impedance designs are available.
Optimize panel utilization, minimize layers, use standard materials (polyimide), avoid unnecessary stiffeners, and increase order quantities. Our team can review your design for cost reduction opportunities.
