6_layers_rigidflex
6L Rigid-Flex – materials: Dupont AP9131 + IT180A; surface finish: HASL

FeatureTechnical Specification
Number of layers 4 – 16 layers
Technology highlightsMixed materials including RF and high speed, standard FR-4, polyimide flex. Adhesiveless or adhesive based polyimide flex constructions, with cover coat or flexible solder mask materials.
Bending performanceBased on the specific design, the bend performance can range from a basic 90 °bend to fit to a full dynamic flex with 360° range of motion in the flex tail that will withstand continuous cycles throughout the product life.
Bending featuresBend radius controls the flexibility of the flex portion of the board. The thinner the material the lower the bend radius and the more flexible the flex section.
