Rigid flex circuit boards

Rigid flex circuit boards are a combination of both rigid and flexible circuit boards.
They consist of multiple layers of flexible circuits that are laminated together with layers of rigid circuits.

This creates a board that can bend and flex in certain areas while maintaining its rigidity in others.
Rigid flex circuit boards are commonly used in applications where space is limited and flexibility is required,

such as in medical devices, aerospace, and military equipment.
They are also used in consumer electronics, such as smartphones and wearables, where they can provide added durability and flexibility.

types of rigid flex circuit boards

There are several types of rigid flex circuit boards, including:

1. Single-sided rigid flex circuit boards:

These boards have one layer of rigid circuit board and one layer of flexible circuit board.

2. Double-sided rigid flex circuit boards:

These boards have two layers of rigid circuit board and one or more layers of flexible circuit board.

3. Multi-layer rigid flex circuit boards:

These boards have multiple layers of rigid circuit board and flexible circuit board.

4. Sculptured rigid flex circuit boards:

These boards have a sculptured shape, with different layers of rigid and flexible circuit board arranged in a three-dimensional shape.

5. Folded rigid flex circuit boards:

These boards are designed to fold or bend in specific areas, allowing them to fit into tight spaces or conform to a specific shape.

6. Stacked rigid flex circuit boards:

These boards have multiple layers of rigid and flexible circuit board stacked on top of each other, creating a compact and efficient design.
