①提高經濟效益：實現(xiàn)免清洗后，相當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(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。紹興錫爐助焊劑廠家供應國標助焊劑***安全焊接。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

1、有助于溶解焊母的氧化膜。 2、防止焊母材的再氧化的進行。 3、降低焊料的張力，能夠加強其潤滑作用。 4、能夠保護焊接的母材 5、一般情況下，如果我們選擇了合適的助焊劑的話，還能夠使焊點起到美觀的作用。</p><p
