背景技术
随着电子技术的不断发展以及集成电路应用的日益普及,助焊剂在电子行业及其相关行业中扮演着越来越重要的角色,现代工业生产中,助焊剂的应用越来越广泛,助焊剂是一种具有化学及物理活化性能的物质,能够除去被焊接金属表面的氧化物或其他已形成的表面膜层以及焊锡本身外表面上所形成的氧化物,以达到被焊接表面能够沾锡及焊牢的目的,助焊剂的功用还可保护金属表面,使在焊接的高温环境中而不被再氧化,同时能够减少融态锡的表面张力,以及促进焊锡的分散及流动等;
助焊剂的种类很多,大体上可分为有机、无机和树脂三大系列;树脂焊剂通常是从树木的分泌物中提取,属于天然产物,不具有腐蚀性,松香是这类焊剂的代表,所以也称为松香类焊剂;助焊剂通常是以松香为主要成分的混合物,是保证焊接过程顺利进行的辅助材料,助焊剂的主要作用是清除焊料和被焊母材表面的氧化物,使金属表面达到必要的清洁度,它防止焊接时表面的再次氧化,降低焊料表面张力,提高焊接性能,助焊剂性能的优劣,直接影响到电子产品的质量传统的助焊剂是由普通松香、助剂和有机溶剂等组成,容易造成焊接后绝缘阻抗较低、容易出现漏电风险、污染环境等问题。
