Devido ao recente aumento de dispositivos eletrônicos montados em automóveis, um grande número de conectores, especialmente conectores estanhados de baixo custo, estão sendo utilizados. Como resultado, a fiabilidade dos seus contactos tornou-se problemática. Além disso, para os conectores que estão sujeitos ao desgaste por atrito causado pelo ciclo térmico e pelas vibrações, a resistência de contato aumenta devido ao desgaste do estanho e à deposição de óxidos, o que gera problemas de mau contato. Este estudo tem como objetivo analisar a mudança na resistência de contato de conectores estanhados desde o início do desgaste por atrito até o final de sua vida útil, do ponto de vista da confiabilidade prática, e observar microscopicamente o traço e as características do desgaste por atrito. Este estudo descobriu que o desgaste e a oxidação dos conectores estanhados começam imediatamente com o desgaste por atrito e, portanto, o acúmulo de pó abrasivo nas áreas de atrito faz com que os conectores cheguem rapidamente ao fim de sua vida útil. Especialmente, foi demonstrado que a amplitude do atrito tem uma influência considerável na vida útil de um conector. Fica claro que a estanqueidade ao ar, a chamada "estanque ao gás" do estanho em uma área de atrito influencia consideravelmente o desgaste por atrito.

Abstract: Due to the recent increase in electronic devices mounted on automobiles, a large number of connectors, especially low-cost tin plated connectors are being used. As a result, their contact reliability has become problematic. Furthermore, for the connectors which are subjected to fretting wear caused by heat cycle and vibrations, the contact resistance increases because of wear of tin and deposition of oxides, which generates problems of poor contact. This study is intended to analyze the change in contact resistance of tin plated connectors from the start of fretting wear to the end of their lifetime from the viewpoint of practical reliability, and to observe the trace and the characteristics of fretting wear microscopically. This study found that wear and oxidation of tin plated connectors start immediately with fretting wear, and thus accumulation of abrasion powder on fretting areas causes connectors to reach to the end of their useful lifetime quickly. Especially, it was demonstrated that amplitude of fretting has a considerable influence on a connector's lifetime. It is made clear that air-tightness, so-called "gas-tight" of tin in a fretting area influences fretting wear considerably.
