Starrflex-Leiterplatten

Starrflex-Leiterplatten sind ein kompliziertes Produkt, das eine intensive Kooperation zwischen dem Leiterplattenanbieter und den Kunden erfordert. Wie generell bei komplexen Produkten, sind auch hier frühe Gespräche zwischen der NCAB Group und dem Designer erforderlich, um das Design im Hinblick auf Herstellbarkeit und Kosten zu optimieren. Die NCAB Group unterstützt Starrflex-Leiterplatten vor allem lokal in Europa und den USA, für höhere Volumenanforderungen aber auch offshore.

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.
