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)，溫州助焊劑要求，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，溫州助焊劑要求，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，溫州助焊劑要求。助焊劑哪家好，杭州正盟環(huán)保工程有限公司。溫州助焊劑要求</p><div

style="text-indent:25px">【正盟環(huán)保】松香和焊錫膏兩者有何分別？無機(jī)助焊劑一般是某些酸或者鹽，比如正磷酸H3PO4，有機(jī)助焊劑主要是某些有機(jī)酸或者有機(jī)鹵素；相對(duì)來說，無機(jī)助焊劑活性相當(dāng)強(qiáng)，去除氧化膜效果較好，但腐蝕性也強(qiáng)，很容易傷及金屬及焊點(diǎn)，一般不能在焊接電子產(chǎn)品中運(yùn)用。焊錫膏就是用機(jī)油乳化后的無機(jī)焊劑，焊接后可用溶劑清洗，不過電路板的有些部位是很難清洗的，所以一般不推薦運(yùn)用焊錫膏。有機(jī)助焊劑活性僅次于無機(jī)助焊劑，也有一定的腐蝕性，且殘?jiān)灰浊逑矗瑩]發(fā)物對(duì)人體有害。松香的主要成份是松香酸和海松酸，一般成中性，液態(tài)松香有一定活性，呈現(xiàn)較弱的酸性，能與金屬表面氧化物發(fā)生反應(yīng)，生成松香酸銅等化合物，并懸浮在焊錫表面，且運(yùn)用的時(shí)候無腐蝕，絕緣性強(qiáng)。一般說來，松香是常用的助焊劑。廣州助焊劑品牌助焊劑保證焊接過程順利進(jìn)行，廠價(jià)直銷。</p><div

①低固態(tài)含量：2%以下傳統(tǒng)的助焊劑有較高的固態(tài)含量（20～40%）、中等的固態(tài)含量（10～15%）和較低的固態(tài)含量（5～10%），用這些助焊劑焊接后的PCB板面留有或多或少的殘留物，而免清洗助焊劑的固態(tài)含量要求低于2%，而且不能含有松香，因此焊后板面基本無殘留物。 ②無腐蝕性：不含鹵素、表面絕緣電阻>1.0×1011Ω 傳統(tǒng)的助焊劑因?yàn)橛休^高的固態(tài)含量，焊接后可將部分有害物質(zhì)“包裹起來”，隔絕與空氣的接觸，形成絕緣保護(hù)層。而免清洗助焊劑，由于極低的固態(tài)含量不能形成絕緣保護(hù)層，若有少量的有害成分殘留在板面上，就會(huì)導(dǎo)致腐蝕和漏電等嚴(yán)重不良后果。因此，免清洗助焊劑中不允許含有鹵素成分。</p><p
