Flexible & Rigid-Flex PCBs

Built to Bend. Engineered to Endure.

At Insight PCB, we specialize in manufacturing flexible and rigid-flex circuit boards that perform in tight spaces, harsh environments, and dynamic applications. By combining rigid FR4 substrates with flexible polyimide sections, our boards offer both strength and adaptability—ideal for 3D packaging, weight reduction, and eliminating connectors.

What Is Rigid-Flex Technology?

Rigid-flex PCBs integrate rigid and flexible layers into a single unified structure, enabling 3D designs that wrap around enclosures, bend at precise points, and reduce interconnect complexity. This helps lower assembly costs, improve reliability, and enhance mechanical durability.

  • Fewer connectors = lower failure risk
  • Lower z-axis height = more compact builds
  • Single assembly = simplified installation and improved trace continuity

Advantages of Flex and Rigid-Flex Boards

  • Dynamic Flexibility: Endures up to 200,000+ bending cycles with standard polyimide
  • Heat Resistance: Polyimide substrates excel in high-temperature environments beyond FR4’s limits
  • Lightweight: Thin, efficient designs ideal for space-constrained applications
  • Improved Airflow: Better thermal management in dense systems
  • Durability: Shockproof, moisture-resistant, corrosion-resistant material options

We also offer adhesiveless and adhesive-based materials from trusted suppliers like Panasonic, DuPont, Shengyi, and others—ensuring consistent mechanical strength, tight bend radii, and long-term performance.

Common Applications

Originally developed for military and aerospace, flexible and rigid-flex PCBs have since expanded across multiple industries:

  • Aerospace & Defense
  • Medical Devices (wearables, implants, diagnostic tools)
  • Automotive Electronics (airbags, dashboards, cameras)
  • Consumer Electronics (smartphones, tablets, wearables)
  • Telecom & IoT Devices
  • Industrial Sensors & Robotics

If you’ve ever seen a brown-orange ribbon inside a printer or camera—that’s a flex circuit in action.

The Future Is Flexible

With the market for flex and rigid-flex PCBs growing faster than traditional rigid boards, choosing the right manufacturing partner is critical. At Insight PCB, we offer technical guidance and manufacturing expertise to support HDI-flex, single- and double-sided flex, and multi-layer rigid-flex boards—custom built to adapt, thrive, and perform.
