Multilayer Rigid Flex PCB
Rigid flex board is a combination of soft board and hard board. It is a circuit board formed by combining the thin flexible bottom layer and rigid bottom layer, and then laminating into a single component. Rigid flexible composite plate has changed the traditional plane design concept and expanded to the three-dimensional space concept. It not only brings great convenience to product design, but also brings great challenges.
The application scope of rigid flex combination board mainly includes: aerospace, such as high-end aircraft mounted weapon navigation system, advanced medical equipment, digital camera, portable camera and high-quality MP3 player. Rigid flexible composite plates are most commonly used in the manufacture of military aircraft and medical equipment. The rigid flexible joint plate brings great benefits to the design of military aircraft, because it not only improves the connection reliability, but also reduces the weight. Of course, the benefits brought by the reduction of the overall volume can not be ignored
Although the cost of rigid flexible composite plate is more expensive than traditional rigid plate, it provides an ideal solution for the project. It uses the interconnection of flexible substrates rather than the connection equipment of multiple PCBs, which is the key to reduce the occupied space and weight, which is required by many designs.
The rigid flexible composite board is flexible and foldable, so it can be used to make customized circuits and maximize the use of indoor available space, which reduces the space occupied by the whole system. The overall cost of the rigid flexible composite board will be relatively high, but with the continuous maturity and development of the industry, the overall cost will continue to decrease, Therefore, it will be more cost-effective and competitive.
