摘要
为节省测试时间并降低测试成本,通过测量SAC0307焊料对铜管的润湿力、爬升高度及焊料对铜片的润湿力和铺展率,建立润湿性和漫流性的对应关系,集成测试获得焊料对铜片的润湿性能和铺展能力。结果表明,松香助焊剂作用下焊料对铜片的润湿力为铜管的1.1倍,丁二酸助焊剂作用下焊料对铜片的润湿力是铜管的1.3倍,松香和丁二酸两种助焊剂作用下焊料在铜管内爬升高度与铜片上铺展率的关系都为指数关系。
To save examination time and cost,the wetting force and climbing of SAC0307 solder on copper tube and wetting force,wetting time and spreading rate of solder on copper sheet were measured.The wettability-spreading ability relation of the solder on copper sheet were then established by the integrated measurement.The results show that the wetting force of the copper sheet under rosin flux is 1.1 times larger than that of the copper tube,which is 1.3 times larger under succinic acid flux.Under the action of rosin and succinic acid flux,the copper pipe climbing height and spreading rate are exponentially dependent.
