| Comparison Item | Rigid PCB | Flex PCB |
|---|---|---|
| Base Material & Flexibility | Made of rigid FR-4 substrate, cannot be bent or folded | Made of flexible polyimide/PET, can be bent, folded, twisted, and shaped freely |
| Form & Installation | Flat, fixed structure; planar installation only | Ultra-thin, lightweight; supports 3D, irregular, and dynamic installation |
| Space & Weight | Thicker and heavier; occupies more internal space | Compact and slim; saves space and reduces overall product weight |
| Wiring & Design | Suitable for standard, static circuit layouts | Supports high-density wiring for complex and miniaturized designs |
| Durability & Fatigue Resistance | Good impact resistance, but prone to cracking under repeated bending | Excellent flex fatigue resistance; ideal for dynamic and moving applications |
| Manufacturing & Cost | Mature process, lower material and production cost | Specialized materials and processes, relatively higher cost |
| Common Applications | Consumer electronics, home appliances, industrial control, power supplies | Wearables, medical devices, automotive electronics, aerospace, camera modules, and foldable devices |
