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

μBGA, CSP in the Reflow Soldering of the Reasons for the High Rate of Cold Soldering
In the reflow soldering process, for μBGA and CSP packaged chips with dense feet (pitch ≤ 0.5mm), there is a risk of higher incidence of cold soldering due to the hidden nature of the soldering site and the difficulty of heat transfer to the solder ball solder joint site. Under the same peak temperature and reflow time conditions, the heat gain

I have been using this, the solder paste does not dry out in winter, the quality is particularly stable Recommended purchase.The seller's service is also very good, customs clearance is fast, and the speed of delivery is unbeatable. The price is also real, worthy of cooperation and trust!
David
Real manufacturers direct sales, product quality is no excuse, with SGS and other well-known institutions of the test report, the user can rest assured that the use of both environmental protection and safety.

It is understood that Fitech solder paste in its domestic has a great influence, in 2014 on the independent research and development and production of T2-T10 particle size of the solder paste, only recently began to layout overseas, in fact, it is also more than 20 years of brand old shop.
Honey
With the use of Fuyinda's solder paste, fast tin down, strong oxidation resistance, good wettability, in particular, it can also be customised for the user's different scenarios of different alloys of solder powder, the configuration of different solder paste. This is for the modern electronics industry, the trend of ultra-micro is becoming more and more obvious, more and more popular with users.
