低固免清洗助焊剂的研究与制备

Preparation and Study of Low-solid and No-clean Flux

研究了免清洗助焊剂的配制及合成工艺,通过微胶囊化对助焊剂活性成分预处理,得到稳定无腐蚀性、残留少的低固免清洗助焊剂,并对所配制助焊剂在软钎焊性、固含量、腐蚀性、卤素含量和酸度等方面进行了性能测试。结果表明:采用复配的有机酸活性物质满足预期要求;制备的免清洗助焊剂多项性能满足规范要求,解决了助焊性与腐蚀性的矛盾。

A study was made on the dispensing and synthesis of no-clean flax.We got a low-solid and no-clean flux,which had good stability.no-corrosion and low-residue by packaging the acvitator of flux.We tested its properties of solderability,solid content,causticity,halid content and acidity by the experiments.The results showed that acvitator which was made up of organic acid complex satisfied prospective demand.The diversified properties of the no-clean flux met the standard requirements,and solved the problem between solderability and causticity.
