Product Details

PCBA Knowledge:

The cohesion of tin-lead solder is even greater than that of water, making solder sphere, so as to minimize its surface area (in the same volume, the sphere has the smallest surface area compared with other geometric shapes to meet the needs of the lowest energy state). The effect of flux is similar to that of cleaner on greased metal plate. In addition, the surface tension is highly dependent on the cleanliness and temperature of the surface. Only when the adhesion energy is much greater than the surface energy (cohesion), the ideal tin staining occurs.

The intermetallic bonds between copper and tin form grains. The shape and size of grains depend on the duration and strength of temperature during soldering. Less heat during soldering can form fine crystalline structure, forming excellent soldering joints with the best strength. Long reaction time, whether due to long soldering time, high temperature or both, will lead to rough crystalline structure, which is gravel and brittle.
