JST-SBSC07 is a silver-free Sn99.3Cu0.7 solder bar — the most economical lead-free alloy for high-volume wave soldering. It runs at a slightly higher pot temperature than SAC305 and saves significantly on alloy cost.
Key features
- Silver-free SnCu alloy, melting point 227 °C
- Lowest-cost lead-free wave alloy
- Low dross formation
- ≈ 1 kg bars, 20 kg carton
Typical applications
- High-volume wave soldering
- Consumer electronics and power supplies
- Tinning baths
