电子元器件引线和印制电路板铜箔等,在贮存中易受空气、水分及其他气体腐蚀而失去金属光泽,降低可焊性甚至因严重锈蚀而影响电性能。电子行业所使用的抗氧化保护剂、防锈油、助焊剂等,通常添加苯并三唑(Benzotriazole简称BTA)做为主要缓蚀剂。
Electronic components lead and printed circuit board copper foil, etc., in storage susceptible to air, water and other gas corrosion and loss of metallic luster, reduce solderability or even due to serious rust and affect the electrical properties. Antioxidants used in the electronics industry, anti-rust oil, flux, usually benzotriazole (Benzotriazole referred to as BTA) as a major corrosion inhibitor.
