The SN100C Lead Free Solder Bar is designed to provide high reliability and stability during wave soldering and PCB assembly. Its silver-enhanced formulation reduces copper erosion and prevents short circuits while maintaining excellent wetting performance. This solder bar ensures consistent joint formation and minimal dross production. I.C.T provides SN100C in standard sizes for wave soldering lines, LED assembly, and electronics production. By using antioxidant protection and controlled alloy composition, manufacturers can achieve repeatable soldering quality while meeting environmental and industry compliance standards.
| Product Features Detailed Introduction
SN100C is being used in thousands of wave soldering machines around the world and has proved its reliability in products exposed to the most severe service environments.
Features：
●The trace addition of Ni means fewer shorts and no shrinkage defects.
●Ni-stabilized intermetallic layer inhibits copper erosion.
●Reliable in harsh environments.
●High ductility ensure long service life of joints subjected to cyclic strain.
●SN100C is formulated for minimal generation of dross.
High Reliability Lead-Free Solder SN100C（Sn-Cu-Ni+Ge）
Features
● The fifinely dispersed microstructure of SN100C makes it possible to roll very thin foil without defects. The eutectic behavior of SN100C (Sn-0.7Cu-0.05Ni+Ge) lead-free preforms means good melting characteristics during reflow. The superior properties of SN100C with low intermetallic growth provide high reliability and flflexibility.
High Temperature Dipping and Tinning Solder SN100C3・SN100C4
Features
●SN100C3 and SN100C4 make it possible to carry out dip soldering and tinning operations with minimum copper erosion.
