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(shuō)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(shuō)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(duì)照，如樣品確認(rèn)OK，后續(xù)交貨時(shí)應(yīng)按原有參數(shù)對(duì)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) 助焊劑市場(chǎng)是良莠不齊，選擇時(shí)對(duì)供應(yīng)商的資質(zhì)應(yīng)該進(jìn)行確切了解，如有必要可以去廠商去看廠，如果是不正規(guī)的焊劑廠商，是很怕這一套的。</p><p
