①提高經(jīng)濟效益：實現(xiàn)免清洗后，直接的就是不必進行清洗工作，因此可以大量節(jié)約清洗人工、設(shè)備、場地、材料（水、溶劑）和能源的消耗，同時由于工藝流程的縮短，節(jié)約了工時提高了生產(chǎn)效率。 ②提高產(chǎn)品質(zhì)量：由于免清洗技術(shù)的實施，要求嚴格控制材料的質(zhì)量，如助焊劑的腐蝕性能（不允許含有鹵化物）、元器件和印制電路板的可焊性等；在裝聯(lián)過程中，需要采用一些先進的工藝手段，如噴霧法涂敷助焊劑、在惰性氣體保護下焊接等。實施免清洗工藝，可避免清洗應(yīng)力對焊接組件的損傷，因此免清洗對提高產(chǎn)品質(zhì)量是極為有利的。 ③有利于環(huán)境保護：采用免清洗技術(shù)后，可停止使用ODS物質(zhì)，也大幅度地減少了揮發(fā)性有機物（VOC）的使用，從而對保護臭氧層具有積極作用。</p><p

style="text-indent:25px">【正盟環(huán)保】助焊劑各成分的作用之緩蝕劑緩蝕劑一般為吡咯類，例如苯并三氮唑（BTA），它是銅的高效緩蝕劑，其加入可以抑制助焊劑中的活性劑對銅板產(chǎn)生的腐蝕。一般認為苯并三氮唑與銅反應(yīng)生成不溶性聚合物的沉淀膜。王偉科根據(jù)化學分析和X射線分析，認為膜的經(jīng)驗式是BTA 4 Cu3Cl2? H2O和（BTA2Cu）2CuCl2?H2O，且聚合物和金屬銅的表面平行，非常穩(wěn)定。BTA在Cu 2 O層上成膜比在 CuO層上成膜更容易，而且膜的厚度厚了近一倍。 BTA的濃度大于l0-3 mol／L時，就可以很好地抑制銅的腐蝕。正盟生產(chǎn)質(zhì)量助焊劑。紹興免洗助焊劑</p><p
