Rigid-flex board is a new type of printed circuit board with both durability of rigid PCB and adaptability of flexible PCB. In all types of PCB, rigid-flex board is the most resistant to harsh application environment, so it is favored by medical and military equipment manufacturers. Our country's enterprises are also gradually increasing the proportion of rigid-flex board in the total output.
Rigid-flex PCB differs from rigid boards or flexible boards in material, equipment and process.
In terms of material, the material of rigid board is FR4 of PCB, and the material of flexible board is PI or PET. There are some problems between the two materials, such as joint, different shrinkage rate of hot pressing, etc. It is difficult for the stability of the product. Moreover, due to the characteristics of three-dimensional space configuration, besides the consideration of XY axis direction stress, Z axis direction stress bearing is also an important consideration. At present, material suppliers provide rigid-flex PCB manufacturers with improved materials suitable for rigid-flex board, such as epoxy or Resin, to meet the joint problem between PCB rigid board or flexible board.
In terms of equipment, due to the difference of material characteristics and product specifications, the equipment of lamination and copper plating parts must be modified. The applicability of equipment will affect the yield and stability of products. Therefore, the applicability of equipment should be considered before entering the production of rigid-flex PCB.
Comparing with general PCB, the advantages of rigid-flex PCB are as follows
Enables optimized packaging, can be bent or folded to fit into small device enclosures.
Increase system reliability
Improves reliability by eliminating separate boards, cables and connectors.
Reduce assembly error
Reduces the errors common in hand wired assemblies.
Reduce packaging complexity
Substantial weight & packaging size reduction is a benefit over wires an wire harnesses.
Better signal transfer
Minimal geometry changes to cause impedance discontinuities
Reduce assembly cost
Cost reduction in purchasing, logistics and assembling because of economisation of extra cables, connectors and soldering processes.
