Fundamental Properties of Polymers for Electronic Applications

Chapter

Abstract

Polymers are widely used as plastics, rubbers, fibres, adhesives, paints and sealants and their use has extended into the field of electronics, where they are used as insulators and encapsulants. In this context they should be good electrical insulators, be free from dielectric losses over the frequency range employed and have a high dielectric strength. Further they should be able to protect electronic components from their surroundings and this in turn depends on them having low permeability to atmospheric vapours and gases, and having good adhesion to the substrate. It is thus the aim of this chapter to explain the chemical and physical structures of polymers and to show how these control their electrical, barrier and adhesive properties.
