Multicore -Lead-free alloys C400m 97SC 3C,2,7-3,2% SAC305 Cuộn 0015"(0,38mm)

97SC (SAC305) is a common lead-free solder alloy with a composition of Sn96.5/Ag3.0/Cu0.5 and a melting point of 217°C.

Composition details and specifications

• 97SC / SAC305: Technical and commercial designation for the lead-free solder alloy.
• Sn 96.5%: Tin, the primary base metal constituting the largest proportion.
• Ag 3.0%: Silver, which enhances the mechanical strength and flexibility of the solder joint.
• Cu 0.5%: Copper, which improves flow characteristics and reduces soldering tip erosion.
• 217°C: The melting temperature (in degrees Celsius) of this alloy.

Key applications

• Used in the assembly of electronic components and printed circuit boards (PCBs), as well as in the repair of high-tech equipment.
• Serves as a replacement for traditional lead-based solders (Sn/Pb) to ensure compliance with environmental safety standards.
