Products Details

Sn42Bi58/Sn42Bi57Ag1/Sn42Bi57.6Ag0.4 lead-free solder wire is made of high-quality and high-purity tin ingots and antimony ingots, supplemented by high-purity silver, and is refined by special techniques using state-of-the-art lead-free solder professional equipment and excellent technology. By adding rare earth elements, the rapid expansion of microcracks in the brittle interface structure is avoided, and the creep fatigue life of the joint is effectively improved. The alloy is reasonable in proportion, and the flux is prepared from high-quality modified resin, organic activator and various additives. It is a lead-free alloy solder wire with excellent welding performance and environmental protection in the lead-free process.


Main Products:
Sn42Bi58
Sn42Bi57Ag1
Sn42Bi57.6Ag0.4


Product Feature:


A. the Sn-Bismuth can be packaged with wire plate in Previous , and now it can be rolled into reel packaging with the new technology 

B. Because it is difficult to add flux because of the brittleness of the Bismuth, it can add the flux by the new technology and process to add the flux in the tin wire that is more convenient to use

C. According to the New craft and Technology, we can make the low temperature Sn-Bismuth wire containing flux to diameter range of 0.8mm.which is  very difficult

D.In the extrusion process, the traditional process will have a line break, bursting flux

After the technical improvement, these phenomena have been well avoided.


E. The coil is neat, flat, smooth, smooth, and will not tangle when using.
F. The solder flux in solder wire is distributed evenly, continuous and not broken. 
G. The solder wire has excellent electrical conductivity and thermal conductivity, and has strong wetting & fast welding speed.
H. No irritation, less smoke, small splash when welding.
I. Less residue after welding, spread evenly, quick-drying, high surface insulation resistance, stable and reliable electrical performance.
J. Solder wire is green environmental protection products, conformed RoHS environmental protection requirements, etc.


Application:
Sn42Bi58/Sn42Bi57Ag1/Sn42Bi57.6Ag0.4  lead-free alloy tin wire is suitable for soldering of heat sensitive components. It is widely used in staged soldering (secondary soldering) in the electronics industry, TV tuner, fire alarm, temperature control original, lightning protection period, Air conditioner safety protectors and other industries.
