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？(二) 鹵素含量：鹵素具有較強(qiáng)的奪取電子能力，微量的鹵素存在會(huì)使得助焊劑的可焊性大幅提升，但鹵素的存在不僅有環(huán)保壓力也會(huì)給產(chǎn)品的可靠性造成一定影響。故助焊劑鹵素含量因應(yīng)用場(chǎng)景而定。比重：助焊劑中溶劑載體與其他組分的密度相差較大，助焊劑在儲(chǔ)存和使用過(guò)程中因?yàn)閾]發(fā)作用而損失掉，造成比重的變化，故比重一定程度上可以反映助焊劑濃度的變化，故比重應(yīng)用于生產(chǎn)中的管控指標(biāo)。固含量：固含量與焊后殘留量（即干凈度）有直接關(guān)系，但非對(duì)應(yīng)關(guān)系，主要是因?yàn)闇y(cè)試溫度和實(shí)際使用溫度上存在差異。所以固含量的是在可焊性和焊后干凈度之間做權(quán)衡。助焊劑哪家好，杭州正盟環(huán)保工程有限公司。</p><div
