6L Rigid-Flex – materials: Dupont AP9131 + IT180A; surface finish: HASL
| Feature | Technical Specification |
|---|---|
| Number of layers | 4 – 16 layers |
| Technology highlights | Mixed 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 performance | Based 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 features | Bend 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. |
