96TSC (SAC387) Electronic Solder
Lead-Free Electronic Solder Alloy
96TSC (SAC387) is a high-quality, lead-free electronic solder alloy composed of approximately 95.5% tin, 3.8% silver, and 0.7% copper. This proprietary refinement of the traditional Sn96.5 Ag3.5 (Sn96, 96S) binary eutectic alloy offers excellent solderability and mechanical strength, making it ideal for demanding electronics manufacturing applications. Its uniform eutectic melting behaviour ensures reliable, consistent solder joints in wave, selective, and dip bath soldering systems.
