7. Conclusion

Polymers are often an advantageous alternative to inorganic, mainly ceramic, dielectrics. This is mainly due to their mechanical properties (lightness, flexibility...), chemical stability and ease of processing in a wide variety of forms (thin films, 3D moldings...) and formulations. Their inherent shortcomings are their limited temperature stability and lower permittivity, but the wide variety of formulations they allow (copolymers, composites, etc.) means they can meet very specific specifications. Today, they are irreplaceable for the production of very high-performance components and interconnection systems.
