FCT Assembly has partnered with Nihon Superior to be able to offer their patented lead-free nickel stabilized tin/copper wave solder alloy – SN100C worldwide. SN100C was developed to offer a technically superior and more economical option to the tin-silver-copper alloys also being considered. SN100C is also significantly less costly than other tin alloys including SAC305.
The finely dispersed micro-structure of SN100C makes it possible to roll very thin foil without defects. The melting behavior of SN100C (Sn-0.7Cu-0.05Ni+Ge) provides excellent characteristics during reflow. Low inter-metallic growth provides high reliability and flexibility. SN100C solder creates less dross than SAC305 alloy. This is due to germanium which is the primary anti-oxidant in SN100C alloy. Germanium reduces the dross rate of SN100C which results in low operating cost than SAC305 alloy.
