Rigid-Flex PCB – Technical specification

A rigid flex printed circuit board (PCB) is a hybrid circuit board design that integrates elements from both hardboard and flexible circuits. Rigid flex PCBs are rigid at some points on the board and flexible at others. Because of this, rigid flex circuits can be folded or continuously flexed while maintaining the shape of areas that need extra support. The circuits are typically multi-layered and are comprised of flexible circuit substrates joined with rigid boards. The flexible layers are buried internally and completely penetrate the rigid sections of the PCB.

One of the key benefits of a rigid flex PCB is its slim profile. The standard dielectric in flexible circuits is .001 – .002”, making it a great choice for ultra thin—and ultra light—packaging needs. Adhesiveless laminates, HDI, and thin copper layers make it ideal for fine line technology, giving you the smallest, thinnest, and lightest solution for your circuit designs.

There are several circumstances that make rigid flex PCBs as an optimal solution. In such situations, these boards are not only worth the investment, but also may be the most cost-effective choice. These include:

1. High-shock and high-vibration environments. Rigid flex PCBs are highly shock resistant and can survive in high-stress environments that would otherwise cause equipment failure.
2. High-precision applications where reliability is more important than cost considerations. In situations where a cable or connector failure would be dangerous, the more durable rigid flex PCBs are preferable.
3. High-density applications.Some assemblies lack the requisite surface area for all the necessary connectors and cables. A rigid flex circuit can economize space to solve this problem.
4. Applications requiring multiple rigid boards. When assemblies get crowded with more than four connected boards, it may be optimal and more cost effective to replace them with a single rigid flex PCB.
