Flux characteristics
Lead-free solder compared with traditional lead solder(Sn-Pb),The biggest drawback of Lead-free solder is not good at the infiltrative,and the diffusion rates is also worse than 10%.This product the SUPER 88S lead-free environmental protection flux is the rosin core wires flux(CORES FLUX) for lead-free solder.Compared with the traditional rosin welding wire flux,it is greatly improved the infiltrative,and the rosin core wires flux achieved the same welding characteristics with the traditional lead solder.This flux type is mid-level active agent ,it can be classified as RMA Type or No Clean Type.The rosin core wires flux satisfied with no clean welding requirements of the ANSI/J-STD-006 ROL0, and accord with specification of J-STS-001 ClassIII .Have good solder results, no adhesion and no corrosive, invasion speed,and satisfy the requirements of rapid welding manual.It is applicable to the high quality electronic products.

Quality
1.Metal components to press 3.1 alloy component standards implementation.
2.Flux should compound machining,it is consistency and non-toxic materials in the quality.
3.Products comply with European WEEE and ROHS toxic substances control requirements.(See SGS harmful elements in the test report)
Use guide
Suggestions for solder iron temperature is 380±5°C.
Mark and packaging
Lead-free welding wire coiled packaging is a coilofwire roll,and 10 rolls installed in a box,Each roll should be on the packaging labeling, and each box will be signed.
such as
1.Manufacturers name and trademark
2.Production batch number
3.Product name, symbols and specifications
4.Inspection mark
5.Environmental protection product marks
