Characterisation of electrical contacts made by non-conductive adhesive

摘要

Characterisation of electrical contacts intended for use with nonconductive adhesives has been performed. The impressions made in the contact area are shown to be dependent on the contact force, and on the surface preparation. At very low contact forces, the presence of insulating oxide layers on the metal surfaces increase the contact resistance dramatically. However, as the contact force is increased, the contact resistance drops rapidly.
