銅鏡腐蝕性：助焊劑的腐蝕性大小是對酸性強(qiáng)弱對基材影響的進(jìn)一步驗(yàn)證，麗水鍍錫助焊劑，衡量腐蝕性大小一般是在使用相當(dāng)普遍的基材銅上做銅鏡腐蝕試驗(yàn)。這項(xiàng)指標(biāo)也是需要在腐蝕性和可焊性之間做權(quán)衡。表面絕緣電阻：表面絕緣電阻的反應(yīng)的是助焊劑焊后產(chǎn)品可靠性，按照不同的測試標(biāo)準(zhǔn)對表面絕緣電阻值的要求也不一樣，按照GBT9491-2002標(biāo)準(zhǔn)SIR大于1011Ω，而按照IPC J-STD-004標(biāo)準(zhǔn)，麗水鍍錫助焊劑，SIR大于108Ω，因測試方法不同，兩者的對比并無意義。但可以確定的是SIR值是越大對焊后產(chǎn)品越有利，麗水鍍錫助焊劑。電化學(xué)遷移：電化學(xué)遷移也是對表面絕緣電阻值的進(jìn)一步要求，在更極端的環(huán)境下考察助焊劑的表面絕緣電阻。當(dāng)然該項(xiàng)指標(biāo)亦越大對焊后產(chǎn)品越有利。除上述詳細(xì)的技術(shù)參數(shù)的考慮，其次還需結(jié)合所需要裝配的電子產(chǎn)品的類別或技術(shù)要求，選擇合適的助焊劑產(chǎn)品；需要對所選助焊劑，進(jìn)行試驗(yàn)驗(yàn)證和有效評估。浙江杭州正盟環(huán)保供應(yīng)***助焊劑。麗水鍍錫助焊劑</p><div

選擇助焊劑時(shí)，有以下幾點(diǎn)建議給使用廠商：一、聞氣味初步斷定是用何種溶劑如甲醇味道比較小但很嗆，異丙醇味道比較重一些，乙醇就有醇香味，雖然說供應(yīng)商也可能用混合溶劑，但要求供應(yīng)商提供成份報(bào)告，一般他們還是會(huì)提供的；但是，異丙醇的價(jià)格大概是甲醇的3-4倍，如果和供應(yīng)商壓價(jià)的厲害，可能這里面的東西就不好說了二、確定樣品這也是很多廠商選擇助焊劑的根本的方法，在確認(rèn)樣品時(shí)，應(yīng)要求供應(yīng)商提供相關(guān)參數(shù)報(bào)告，并與樣品對照，如樣品確認(rèn)OK，后續(xù)交貨時(shí)應(yīng)按原有參數(shù)對照，出現(xiàn)異常時(shí)應(yīng)檢查比重，酸度值等,助焊劑的發(fā)煙量也是很重要的一個(gè)指標(biāo)。三、看資質(zhì)
