1、助焊劑的基本組成國內(nèi)外助焊劑一般由活化劑、溶劑，江蘇活性助焊劑，江蘇活性助焊劑，江蘇活性助焊劑、表面活性劑和特殊成分組成。特殊成分包括緩蝕劑、防氧化劑、成膜劑等。環(huán)保助焊劑，用于太陽能光伏組件行業(yè)。杭州正盟環(huán)保生產(chǎn)。江蘇活性助焊劑</p><div style="width:100%;text-align: center;"><img

style="text-indent:25px">【正盟環(huán)?！棵馇逑粗竸?要使焊接后的PCB板面不用清洗就能達到規(guī)定的質(zhì)量水平，助焊劑的選擇是一個關鍵，通常對免清洗助焊劑有下列要求： 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)的助焊劑因為有較高的固態(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層，若有少量的有害成分殘留在板面上，就會導致腐蝕和漏電等嚴重不良后果。因此，免清洗助焊劑中不允許含有鹵素成分。北京助焊劑標準環(huán)保級助焊劑，杭州正盟環(huán)保批發(fā)生產(chǎn)。</p><div
