Unmanned aerial vehicle(UAV) Rigid-Flex PCB(R-FPCB)

Rigid-flex PCB is a new type of printed circuit board with both the durability of rigid PCB and the adaptability of flexible PCB. Among all types of PCB, the combination of hardware and software has the strongest resistance to harsh application environment PCB, so it is favored by industrial control PCB, medical PCB and military equipment PCB manufacturers.

If according to the process classification, the way of joining the soft board and the hard board can be divided into two categories: the soft and hard composite board and the soft and hard combination board. The difference lies in the technology of the soft and hard composite board. In the process, the soft board and the hard board can be combined. Among them, there are common blind hole and buried hole design. Therefore, the circuit design with higher density can be adopted, while the technology of soft and hard board is to separate the soft board from the hard board After fabrication, a single circuit board is fabricated by pressing. The design has signal connection but no through hole.

There are differences in material, equipment and process between hard and soft board. In terms of materials, the material of hard board is FR4 of PCB, and the material of soft board is PI or pet. There is joint between the two materials, The problem of different hot compression shrinkage rate is a difficult point for the product stability. Moreover, due to the three-dimensional space configuration of soft and hard PCB, in addition to the consideration of XY axis stress, z-axis stress bearing is also an important consideration. At present, some material suppliers provide improved materials for PCB hard and soft board manufacturers, such as epoxy resin Or modified resin (resin) and other materials to meet the PCB hard board or soft board bonding problems.

Rigid-flex PCB are widely used: Wearable intelligent products, semiconductor PCB, digital camera PCB, tablet computer PCB, mobile phone PCB, module PCB, navigation PCB, automobile brake system PCB, IC PCB board, T card PCB, SSD PCB, graphics card PCB, solid state disk PCB, battery PCB board, WiFi PCB, camera lens PCB, industrial control PCB, etc.
