選擇助焊劑時，有以下幾點建議給使用廠商：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)商提供成份報告，一般他們還是會提供的；但是，異丙醇的價格大概是甲醇的3-4倍，如果和供應(yīng)商壓價的厲害，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，在確認樣品時，應(yīng)要求供應(yīng)商提供相關(guān)參數(shù)報告，并與樣品對照，如樣品確認OK，后續(xù)交貨時應(yīng)按原有參數(shù)對照，出現(xiàn)異常時應(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指標(biāo)。三、看資質(zhì) 助焊劑市場是良莠不齊，選擇時對供應(yīng)商的資質(zhì)應(yīng)該進行確切了解，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

③活性化松香（RA）及超活性化松香（RSA）：在活性化松香助焊劑中，添加的強活性劑有鹽酸苯胺、鹽酸聯(lián)氨等鹽基性有機化合物，這種助焊劑的活性是明顯提高了，但焊接后殘留物中氯離子的腐蝕變成不可忽視的問題，所以，在電子產(chǎn)品的裝聯(lián)中一般很少應(yīng)用。隨著活性劑的改進，已開發(fā)了在焊接溫度下能將殘渣分解為非腐蝕性物質(zhì)的活性劑，這些大多數(shù)是有機化化合物的衍生物。杭州正盟環(huán)保工程有限公司坐落于杭州錢江經(jīng)濟開發(fā)區(qū)。江蘇鋁錫助焊劑</p><p
