⑵助焊劑應(yīng)有良好的熱穩(wěn)定性，一般熱穩(wěn)定溫度不小于100℃。 ⑶助焊劑的密度應(yīng)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(jìn)焊料對(duì)母材的潤(rùn)濕。 ⑷助焊劑的殘留物不應(yīng)有腐蝕性且容易清洗；不應(yīng)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(xué)性能穩(wěn)定，易于貯藏。杭州正盟環(huán)保工程有限公司專(zhuān)業(yè)生產(chǎn)水基環(huán)保免清洗焊劑。江蘇助焊劑批發(fā)</p><p
