style="text-indent:25px">【正盟環(huán)保】電子工業(yè)助焊劑之如何從技術(shù)性能指標(biāo)的角度選擇助焊劑？(一) 助焊劑是電子工業(yè)中相當(dāng)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(biāo)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(xiàng)技術(shù)性能指標(biāo)： 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(yīng)，酸性越強(qiáng)PH值越低，助焊劑的去氧化能力則越強(qiáng)，但同時(shí)帶來的過反應(yīng)的問題而把金屬基材腐蝕。故助焊劑酸性的大小應(yīng)與金屬材料敏感性相匹配，精密焊接不宜選擇酸性太強(qiáng)的助焊劑，或者焊后需要進(jìn)行清洗。浙江杭州正盟環(huán)保供應(yīng)***助焊劑。廣州助焊劑特性</p><p
