Rigid-Flex PCBs

Rigid-flex is a complicated product that demands a lot of interaction between the PCB provider and the customers. Like other complex products, early discussions between NCAB Group and the designer is necessary to optimize the design for manufacturability and to optimize costs. NCAB Group supports rigid-flex boards both locally in Europe and US as well as off-shore for higher volume requirements.

Please contact your local NCAB Group company if you need further information or assistance, we are happy to help you.

Feature NCAB´s 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.
Bend 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.
