The technology of rigid flex PCB is to make the rigid board and flexible board separately and then press them into a single board with signal connection but no through-via design. Among them, the blind via and buried via design can be commonly achieved to create a higher density circuit design. The difference of the two lies in the technology of the rigid flex PCB, which can combine the rigid board and the flexible board during the manufacturing process. Therefore, it is favored by industrial control, medical, and military equipment manufacturers while many enterprises are also gradually increasing the proportion of rigid-flex PCB in total output.Ĭlassification of rigid flex printed circuit boardsĪccording to the manufacturing process, the method of combining the rigid board and the flexible board can be divided into two types of products, the rigid flex clad plate and the rigid flex PCB. Among all types of PCBs, this combination is the best to deal with harsh application environments with high resistance. Rigid-flex PCB printed circuit board is a new type of PCB that combines the durability of rigid PCB and the adaptability of flexible PCB.
