Solderalloys are selected for their properties to flow, sealing ability, electrical conductivity, and for general body work to provide a smooth surface for finishing.
选择软焊合金时应考虑其流动性、密封能力和导电性,此外?以提供光滑的加工表面。

The oxide thinning process could not only reduce the coalescent resistance of solderalloys during melting but also make the complete removal of oxide with flux easier.
The solderalloys especially the lead-free solderalloys become the focus of study because of the quick development of the microelectronics and the surface mount technology (SMT).
