SAC300-1103 Lead-free solder bar

The SAC300-1103 lead-free solder bar is meticulously engineered with a precise metal alloy composition, predominantly comprised of 97% tin (Sn) and 3% silver (Ag). This eutectic mixture is carefully formulated to achieve optimal soldering performance while adhering to global environmental standards, particularly RoHS compliance.

Features and benefits

  • There are few metal impurities and low oxide content, and the purity is extremely high.
  • After melting, the tin liquid surface is smooth and flat, with low viscosity and excellent fluidity.
  • Unique high oxidation resistance and very little tin slag.
  • It has good wettability, low surface tension, easy soldering, bright and full solder spots, and stable and reliable welding quality.
  • It is a green and environmentally friendly product that complies with RoHS and other environmental protection requirements.
