Novel contact connector materials such as extrinsic conducting polymers improve contact performance and enables device miniaturisation. This paper presents an investigation of conducting polymer materials to minimise the effect of fretting at the contact interface of connector terminals. Initial experimental studies are presented and a mechanical model is used to describe the polymer interface slip and stick characteristics. For fretting to be minimised the polymer must be sufficiently elastic, with a high coefficient of friction with the contacting terminal, and a sufficient normal force to ensure no slip. Electrical experimental studies of a polymer-tin interface have also been carried out to characterise contact resistance performance under fretting conditions. A resistance model of the polymer interface is developed.
