Sn/Ag3.0/Cu0.5 Solder Paste is designed for high-performance, lead-free soldering applications. The addition of silver and copper enhances the mechanical strength, thermal fatigue resistance, and conductivity of the solder, making it ideal for advanced electronics and critical soldering tasks.
Advanced Alloy Technology
Precise Melting Range:Melts between 217ºC and 219ºC, ensuring smooth and consistent soldering.
Enhanced Performance:Provides strong, durable joints with excellent thermal and electrical conductivity.
Silver and Copper Addition:The inclusion of silver and copper improves the solder's mechanical properties, making it suitable for high-reliability applications. Ideal for high-reliability, lead-free soldering tasks requiring strong, durable joints and excellent thermal stability. Suitable for electronics assembly, repair work, and other industrial applications.
Our product comes in environmentally friendly green cans, with a default weight of 500 grams, customizable to meet specific customer needs. Each can is labeled with essential details including the product model, alloy composition, batch number, and weight. Additionally, the solder paste label provides concise instructions for use, along with safety and health guidelines. "ZS.HX Zhongshi" is the proud registered trademark of our company.
For enhanced storage stability, store the solder paste in a cool environment at 5 ºC. When kept at room temperature of 25 ºC or in a controlled setting of 35 ºC, monitor the viscosity periodically over 180 days at 25 ºC and 90 days at 35 ºC, ensuring the increase in viscosity remains below 10%.
Regarding continuous printing stability, maintain the same solder paste for 8 hours of printing and assess the viscosity using a steel net. Continue this process after storage and repeat for 3 consecutive days. Consistent viscosity is confirmed after three days of ongoing printing.
