助焊劑是電子工業(yè)中相當重要的輔助材料之一，它在電子裝配工藝中影響電子產(chǎn)品質(zhì)量與可靠性。隨著現(xiàn)代信息電子工業(yè)的迅猛發(fā)展，助焊劑的使用量大要求越來越高。如何能在眾多的助焊劑中挑選一款適合自己所需要的產(chǎn)品，滿足波峰焊工藝使用，從技術(shù)性能指標的角度可供初步參考篩選?到適合的產(chǎn)品，首先需要正確理解其各項技術(shù)性能指標： PH值：助焊劑去除焊接金屬表面的金屬氧化物通過酸性反應，酸性越強PH值越低，助焊劑的去氧化能力則越強，但同時帶來的過反應的問題而把金屬基材腐蝕。故助焊劑酸性的大小應與金屬材料敏感性相匹配，精密焊接不宜選擇酸性太強的助焊劑，或者焊后需要進行清洗。正盟牌助焊劑，歡迎選購。</p><div style="width:100%;text-align: center;"><img

⑶助焊劑的密度應小于液態(tài)焊料的密度，這樣助焊劑才能均勻地在被焊金屬表面鋪展，呈薄膜狀覆蓋在焊料和被焊金屬表面，有效地隔絕空氣，促進焊料對母材的潤濕。 ⑷助焊劑的殘留物不應有腐蝕性且容易清洗；不應析出有毒、有害氣體；要有符合電子工業(yè)規(guī)定的水溶性電阻和絕緣電阻；不吸潮，不產(chǎn)生霉菌；化學性能穩(wěn)定，易于貯藏。杭州正盟環(huán)保工程有限公司專業(yè)生產(chǎn)水基環(huán)保免清洗焊劑。廣東助焊劑危害</p><p
