PCB rigido-flessibili

Il PCB rigido-flessibile è un prodotto complicato che richiede un’intensa interazione tra il fornitore di PCB ed i clienti. Come per altri prodotti complessi, sono necessari dei colloqui preliminari tra il Gruppo NCAB ed il progettista, al fine di ottimizzare la progettazione per la producibilità e per ottimizzare i costi. Il Gruppo NCAB supporta schede rigido-flessibili sia a livello locale in Europa e negli Stati Uniti, sia off-shore per esigenze di volume più elevate.

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.
