When problems arise in Solder Paste Production such as erosion or washing, it is necessary to analyze the causes and check whether the erosion method and protective measures are appropriate. JJY, Solder paste manufacturer, suggests to our friends that, from the perspective of tin powder, we look at how to solve undesirable phenomena caused by Solder Paste, such as astringency and other conditions.

The passivation layer of the tin-powder particles is relatively thin, which helps to better improve the stability of the Solder paste and reduces the probability of solder beads. At the same time, the particle surface is smooth with few defects, which reduces reaction with the Flux and improves the viscosity stability of the solder paste.

Consider the additional benefits of the powder. Its overall spherical shape is highly accurate, which benefits package printing, syringe dotting and uniform tin deposition. In addition, reducing the friction and pushing between particles during application helps protect the passivation layer from damage.

The powder has good fluidity and high density, which lets it fill smaller holes and smaller syringe needles for tin dispensing, and supports the future trend toward lighter products.

The particle size distribution is relatively narrow, so the solder paste is also highly uniform. This favors consistent solder paste deposition during printing and consistent viscosity across batch numbers. The powder's good fluidity facilitates solder paste printing and helps reduce residual bridges while producing round, well-formed joints.

We select high-purity raw materials and, under the control of quality engineers, adopt unique deep-purification smelting, which effectively reduces the oxidation level of the alloy in air. This lowers the defect rate during soldering while ensuring post-solder quality.
