Rigid flex circuits have been used in the military and aerospace industries for more than 20 years.Rigid flex circuits combine the best of both rigid boards and flexible circuits integrated together into one circuit. The two-in-one circuit is interconnected through plated thru holes. Rigid flex circuits provide higher component density and better quality control.

Electronic devices have taken over a major part of our daily lives. The wide range of devices from mobile phones to servers, regardless of their size and their use are now designed to be flexible, lightweight and efficient. It may be their forms, size or features, it has one thing in common - they include flexible printed circuits.
A flexible printed circuit board (PCB flex, flex PCB or FPC) is a circuit technology that involves using a high-performance plastic substrate, such as polyimide. The flex circuits are often used as connectors in applications where mechanical torsion, saving space or production constraints limit the use of rigid circuits wired or manual wiring.
The flexible printed circuits represent an advanced and innovative approach to connecting electronic components. They are characterized by a medium between conventional circuit boards and beams.
1. Small footprint
2. Saves space and weight: the saving space and weight : mini 60% compared to conventional circuits.
3. Ease of integration: Due to the characteristics of flexible printed circuits, integrated in its environment is facilitated. You can fold it so that it matches your expectations.
4. Difficult conditions: The materials (polyimide dielectric layer, varnish ...) that covers and protects the flexible printed circuit guarantee operation even under difficult operating conditions (waterproof, moisture-resistant, shockproof , oil at high temperature, corrosion resistant ...).
5. Vibrations: Due to their flexibility and low density, flexible circuits are very resistant to strong vibrations, which ensures the robustness necessary for high reliability applications: Aviation, military, ..
Flexible printed circuits are used in applications requiring compact connections. The switching matrices computer keyboards or other compact electronic products such as digital cameras, PDAs, ... are a good example of mass application for flex circuits.
