摘要
用润湿力试验和铺展试验来确定活性组分和溶剂,研制了一种以醇作为溶剂的免清洗助焊剂。结果表明:该助焊剂选用复合有机酸和有机胺作为主要活性成分,有机酸的配比为1∶2时有很好的助焊效果,选择醇类作为溶剂对有机酸的溶解性好;该免清洗助焊剂助焊性能良好,腐蚀性小,焊后可以免于清洗。
The properties of wetting power and spreadability with active agent and dissolvent were tested according to the industry standard, a new no -learn flux was researched which chooses alcohols for the dissolvent. The result shows that when the active agent were chosen from the organic acid and organic amine for compounding;and when the proportion by weight of organic acid B and organic acid C is 1：2 has a good welding performance, the dissolvent is alcohols has a good dissolvability to the organic acid, the flux is good welding performance,low -corrosive, the residue after welding need not be cleaned.
