Abstract

Novel contact connector materials such as conducting polymers are becoming available which improve performance and enable further miniaturisation. Studies of a polymer-tin interface have been carried out to characterise contact resistance performance under fretting conditions. Degradation mechanisms have been identified using contact resistance measurements and surface analysis tools. These mechanisms have been shown to be different to those found in the tin-tin interface. The polymer-tin interface performs significantly better than a clean tin-tin interface, requiring more than three times the number of fretting cycles to fail (attaining 200 m/spl Omega/). The study shows that debris is not deposited at the end of the wear track as in a tin-tin interface. Additionally, once the contact resistance attains high values, the polymer-tin interface recovers to low values. The elastic contact is proposed as an advantageous characteristic of conducting polymers which can be used to eliminate fretting at the contact interface.

外源导电聚合物与锡界面的微动腐蚀研究

新型接触连接器材料，如导电聚合物，可以提高性能并进一步小型化。聚合物-锡界面在微动条件下的接触电阻性能进行了研究。降解机制已确定使用接触电阻测量和表面分析工具。这些机制已被证明是不同于那些发现在锡-锡界面。聚合物-锡界面的性能明显优于干净的锡-锡界面，需要三倍以上的微动循环次数才能失效(达到200 m/spl ω /)。研究表明，磨损轨迹的末端并没有像锡-锡界面那样沉积碎屑。此外，一旦接触电阻达到高值，聚合物-锡界面恢复到低值。弹性接触是导电聚合物的一个有利特性，可用于消除接触界面处的微动。
