melting point of tin amounts to 231.8degC. A further solder test presented a considerable decrease in the wetting behavior after reflow aging

. The flux's melting point is lower than alloy, we need to control the temperature the time of flux melt and volatilize. When the flux volatilize, the time of the alloy melt is also need to be controlled

. This method is very common, but requires additional equipment and operating steps, which increases the cost. The second is to use solder alloys with different melting points

. The more efficient the heat transfer during the soak phase the less time is needed. Reflow – This is the stage where the temperature within the reflow oven is increased above the melting point of the solder paste causing it to form a liquid

. In other cases, sol- ders with different melting points can be used. For example, if the bottom-side is reflowed first using a high melt point solder (greater than 183°C
