The novel technology from the field of medical engineering turns a plurality of materials into electrically conducting and solderable printed circuit boards that were not suitable for an assembly with electronic components up to this point in time.
So far, solderable paper FPCs (FPC = Flexible Printed Circuit) are a novelty and, as a consequence of the new technology, offer a plurality of applications. They are affordable, have no diffusion barrier and are thus suitable for large-scale applications such as wallpapers or advertising spaces.
PET may also serve as a basic material for FPCs. This plastic material is cheaper than polyimide, is characterised by a very good strength, a high resilience, and a low weight. When coated with a thin aluminium layer, which is rendered solderable via plasma metallisation, the PET FPCs may be equipped with components.
