和WEEE指令的實行，無鉛化對助焊劑的性能提出了更高的要求，助焊劑已由傳統(tǒng)的松香型向無鹵、無松香、免清洗、低固含量方向發(fā)展，其組成也隨之發(fā)生了相應的變化，各組分的相互作用，使助焊劑的性能更加優(yōu)良。

①提高經濟效益：實現免清洗后，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效率。 ②提高產品質量：由于免清洗技術的實施，要求嚴格控制材料的質量，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，可避免清洗應力對焊接組件的損傷，因此免清洗對提高產品質量是極為有利的。 ③有利于環(huán)境保護：采用免清洗技術后，可停止使用ODS物質，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】助焊劑成分近幾十年來，在電子產品生產錫焊工藝過程中，一般多使用主要由松香、樹脂、含鹵化物的活性劑、添加劑和有機溶劑組成的松香樹脂系助焊劑.這類助焊劑雖然可焊性好，成本低，但焊后殘留物高.其殘留物含有鹵素離子，會逐步引起電氣絕緣性能下降和短路等問題，要解決這一問題，必須對電子印制板上的松香樹脂系助焊劑殘留物進行清洗.這樣不但會增加生產成本，而且清洗松香樹脂系助焊劑殘留的清洗劑主要是氟氯化合物.這種化合物是大氣臭氧層的損耗物質，屬于禁用和被淘汰之列.仍有不少公司沿用的工藝是屬于前述采用松香樹指系助焊劑焊錫再用清洗劑清洗的工藝，效率較低而成本偏高。廠家供應環(huán)保級助焊劑，***，助您安全焊接。</p><div
