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

Distance requirements for solder paste process SMD pads and inline pads?

Distance requirements for solder paste process SMD pads and inline pads?

In the solder paste process (SMT), the minimum safe distance between the SMD pads and the inline pads is recommended to be 0.4mm to 1mm. this distance effectively prevents solder paste bridging, component interference, and ensures soldering reliability.

Specific meaning and analysis of the 5M1E of production operations

Specific meaning and analysis of the 5M1E of production operations

5M1E is an acronym for the six core elements used in production management and quality control to analyse the quality of a product or process, which are known as Man, Machine, Material, Method, Measurement and Environment. The initial letters of these six factors are M and E, so they are collectively called 5M1E.
