②提高產(chǎn)品質(zhì)量：由于免清洗技術(shù)的實(shí)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(guò)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(shí)施免清洗工藝，可避免清洗應(yīng)力對(duì)焊接組件的損傷，因此免清洗對(duì)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(jī)物（VOC）的使用，從而對(duì)保護(hù)臭氧層具有積極作用。廠家生產(chǎn)專(zhuān)為針對(duì)太陽(yáng)能光伏行業(yè)開(kāi)發(fā)的一款環(huán)保型免清洗助焊劑，可免除清洗工序。江蘇助焊劑銷(xiāo)售</p><p
