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.

Lead-free solder wire

Our solder wires, which are lead-free, come with a variety of features including nickel plating, high activity, and water solubility. They are designed for low spatter and are suitable for both low and high-temperature applications, including aluminum and automated soldering processes. These wires are extensively utilized in aerospace, electronics, electrical toys, and automotive industries. Additionally, they comply with the ROHS and REACH directives.

Tin-lead solder wire

We provide the cumstomers tin-lead solder wire with different diameters.Its production process minimizes solder slag and prevents lump formation, preserving the solder's shine. Benefits include a smooth, pure surface for optimal melting, cost savings by avoiding expensive metals, compatibility with current soldering temperatures, low sensitivity to impurities, fewer surface defects, and improved reliability over traditional solders.
