When it comes to modern electronics, the most important part of the device has got to be the circuit board. When people think about circuit boards, they most likely have the traditional type as an image in their head. However, there is actually a new type of hybrid circuit board that many new devices use. This circuit board is known as a rigid flex circuit boards.
Basically, the hybrid combines the best aspects of the two more traditional boards, those being hardboard and flexible. They work by being able to bend in certain spots of the board but also being rigid in other parts of the board. By being designed this way, they can flex repeatedly but still stay hard to maintain shape. The boards tend to be multilayered with the substrates of the board being attached to the rigid sections.
The most common rigid flex board is known as a “flex to install” board. What this means is that the board will bend once to be able to be installed and after that, it remains quite rigid in the product. However, there are also certain times when the board needs to be able to flex on a continual basis. In the technology industry, these boards are known as dynamic flex boards. They are developed with very careful consideration so that they enjoy a long lifetime of use, up to hundreds of thousands of flexing sessions.
There are quite a few varied instances when these types of boards are needed and more than appropriate. One of the most common scenarios is when the environment the circuit board is situated in undergoes a lot of vibrations or shocking movements. There are also times when the boards are installed in precision instruments and the cost is not really an issue. In … Read More ...Read More →
