This application note will illustrate surface tension and contact angle measurements of molten solder using the FTÅ200 system. The FTÅ200 has an optional Environmental Chamber which can maintain a temperature and, if desired, an atmosphere. The temperature was set to 200°C, hot enough to melt the 63% tin, 37% lead Kester “44” brand rosin core solder used in this work. The atmosphere was air.
