Abstract

Corrosive gas environmental tests are used to predict the reliability of electrical connectors used in data system products under conditions found in business office environments. A corrosive gaseous environmental acceleration test called G1(T) is evaluated through variations in testing conditions, in particular for those which differ from outside testing standards used in the connector industry. An investigation of those features of various acceleration tests which could be recommended for adoption into an industry-wide testing standard are reported. These studies could be important for gaining a consensus for support of an acceleration testing practice to predict corrosion reliability during the life of a product. Copper, nickel, and porous gold coupons (electroplated gold over nickel over copper) are used to determine the effects of each corrosive gas test environment. The corrosion of copper is quantified by coulometric reduction, while nickel is evaluated by energy dispersive X-ray fluorescence analysis. The porous gold coupons are visually examined for the presence of pore and creep corrosion, which makes it possible to determine the degree of environmental exposure quickly.<>

电触点腐蚀气体环境试验

腐蚀性气体环境试验用于预测数据系统产品中使用的电连接器在商业办公环境条件下的可靠性。称为G1(T)的腐蚀性气体环境加速测试通过测试条件的变化进行评估，特别是那些与连接器行业中使用的外部测试标准不同的测试条件。对各种加速度测试的特征进行了调查，这些特征可以被推荐采用为行业范围的测试标准。这些研究对于获得共识，支持加速测试实践来预测产品生命周期内的腐蚀可靠性非常重要。铜，镍和多孔金券(电镀金在镍上，铜上)用于确定每种腐蚀性气体测试环境的影响。铜的腐蚀用库仑还原法测定，镍的腐蚀用能量色散x射线荧光法测定。通过目视检查多孔金券是否存在孔隙和蠕变腐蚀，从而可以快速确定环境暴露程度。
