THIN-FILM COMPONENT COMPRISING A SUBSTRATE WITH AN ELASTIC COATING

摘要

The invention relates to a thin-film component, for example a capacitor, a resistor and a coil, as well as combinations thereof. Said component comprises a substrate of an electrically insulating material (preferably glass), which is provided with two U-shaped side contacts and with an electrical structure which is electrically connected to both side contacts. The invention is characterized in that a flexible layer (preferably polyimide) is situated between the substrate and at least one of both legs of each of the U-shaped side contacts, which flexible layer is provided directly on the substrate surface, and in that the modulus of elasticity of the material of the layer is below 50 GPa. By virtue of this measure, it is achieved that the components demonstrate a better resistance to standard bending tests. As a result, the product-failure percentage is reduced if these components are employed in flexible PCBs or in PCBs which are subjected to a vibration.
