①提高經(jīng)濟(jì)效益：實現(xiàn)免清洗后，相當(dāng)直接的就是不必進(jìn)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(yán)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(jìn)的工藝手段，如噴霧法涂敷助焊劑、在惰性氣體保護(hù)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(hù)：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(hù)臭氧層具有積極作用。杭州新型助焊劑</p><p
