Abstract :
The properties of eutectic solder paste (Sn63/Pb37) in an RMA flux and solder powder have been investigated using differential scanning calorimetry. The results show that the melting point for both the paste and powder samples occurs at 182 degrees C and also the effects of supercooling occurs for both the paste and the powder samples. The supercooling results are of vital importance in the modelling of the thermal processes for electronics manufacture using surface mount technology.
