In this paper,three types of wettability evaluation methods,namely wetted spreading area test,wetting force test and contact angle test,have been used to measure the wettability of Sn-37Pb using different fluxes which include different concentration of the rosin.
分别用3种润湿性测量方法(铺展面积测量法、润湿力测量法和润湿角测量法)做了不同松香浓度和不同助焊剂下的钎料Sn-37Pb的润湿性,以及在不同助焊剂下润湿性。
The formula that expresses the relationship between the wetting angle () and spreading area (S) has set up by mathematical model.
通过建立简化的数学模型,得出了润湿角与钎料熔滴铺展面积间的数学关系式。
