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. |
| Materials | RA copper, HTE copper, FR-4, polyimide, adhesive |
| Copper weights (finished) | ½ ounce, 1 ounce, 2 ounce, 3 ounce |
| Minimum track and gap | 0.075mm / 0.075mm |
| PCB thickness | 0.4mm to 3mm |
| PCB thickness in flex section | 0.05mm to 0.8mm |
| Maxmimum dimensions | 457mm to 610mm |
