Solder Powder

Solder Powder

Solder powder is a kind of connecting material used in electronic industry, which is mainly composed of Sn (tin) and other metals (such as Pb, Ag, Cu, etc.) as alloy powder. Fitech solder powder adopts Fitech's patented powder making technology - liquid phase molding spherical alloy powder technology, which applies the principle of ultrasonic cavitation effect, and can be used for the preparation of ultra-fine solder powder T6 (5~15μm), T7(2~11μm),T8 (2~8μm),T9 (1~5μm),T10 (1~3μm),and has already been mass-produced on a large scale. This technology enables the solder powder to have excellent sphericity and low oxygen content, which ensur

How to improve the mechanical reliability of SAC solder paste

SAC series solder paste is a common medium-temperature solder in semiconductor packaging. This type of solder paste can be used for soldering work at relatively high temperatures, and the strength after soldering is considerable. However, as the thermal stress on the solder joint accumulates, there is a certain degree of deformation between the sol
