Our Advantages

Enhance your assembly efficiency with a paste that offers reduced voiding and strong, durable joints. Ideal for high-density PCBs, our solder paste maintains its integrity under rigorous conditions, ensuring that each application is precise and dependable.

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.
