Product Features

42Sn-58Bi Soldering Tin Paste is a high-performance solder paste composed of 42% tin (Sn) and 58% bismuth (Bi). This alloy is known for its low melting point of 138°C (280°F), making it ideal for applications requiring lower temperature soldering processes. It is specifically designed for surface mount technology (SMT), fine pitch components, and other sensitive electronics assemblies.

It forms strong, reliable joints, reducing the risk of defects and ensuring consistent, high-quality results. Perfect for intricate electronic assemblies, it guarantees the performance and durability you need.

Our 42Sn-58Bi Soldering Tin Paste is crafted to meet the highest standards, reflecting your dedication to excellence. Trust in our product to help you achieve impeccable results.

Packaging & Shipping

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.

 

Our Advantages

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.
