style="text-indent:25px">【正盟環(huán)保】低松香型免清洗助焊劑是一種專為用于機(jī)器焊接高級(jí)多層電路板的助焊劑。此類助焊劑助焊能力強(qiáng)，發(fā)泡性能好，不含鹵素，在焊接時(shí)產(chǎn)生的煙霧和其殘余物對(duì)焊料和裸銅無(wú)腐蝕性，在較高的預(yù)熱溫度100℃～130℃時(shí)得到狀態(tài)。因此，它是一種較理想的免清洗助焊劑，在板子上具有極高的表面絕緣阻抗以及快干的效果，板子的粘膩感亦可以減少到低的程度，能夠輕易地通過測(cè)試程序，適用于任何高0端線路板波峰焊、噴焊及手工焊。該助焊劑中溶劑既要對(duì)焊接表面具有良好的保護(hù)作用，又要有適當(dāng)?shù)酿ざ取８叻悬c(diǎn)的醇保護(hù)效果較好，但黏度大、使用不便；低沸點(diǎn)的醇黏度低，但保護(hù)性差，因而可以考慮選擇混合醇的方法。有資料表明，乙醇、乙二醇、丙三醇和乙二醇丁醚的配比(質(zhì)量比)為2:8:8:1的混合溶劑效果上佳。衢州助焊劑危害</p><p
