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 microstructure 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 intermetallic 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 drossing rate of SN100C which results in low operating cost than SAC305 alloy.
