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

Mechanism of P segregation at the weld interface  of ENIG Ni(P) coatings

Mechanism of P segregation at the weld interface  of ENIG Ni(P) coatings

P segregation is a phenomenon that occurs when metallurgical reactions between Ni and Sn in the solder lead to an enrichment of P in the Ni(P) layer near the weld interface when reflow soldering with ENIG Ni(P) layers.
