Rigid PCBs' applications range from small electrical devices to large aerospace, military and medical fields.  And flex printed circuit boards  are built of flexible substrate. They have lower thickness,  lighter weight, and they are dynamically bendable, so they can save space They also have equally vast applications because of their excellent electrical and thermal performance.

Flex-rigid PCBS are boards which combile the technology of  flexible board and rigid board. They consist of multiple layers of flexible circuit substrates attached to one or more rigid boards either externally or internally.  Therefore they own the advantages of both rigid printed circuit boards and flex circuit boards. Rigid-Flex products provide reliable integration of multiple rigid printed circuit board assemblies into a single PCB module capable of supporting assembly, space/weight savings, and mechanical stability.

 The advantages of rigid flex board includes:

1)  ruducing products' weight 

2)  temperature resistance is excellent

3)  being more flexible 

4)  with good reliability
