Soldering Advantage

Its clear residue allows easy inspection of solder joints and the very low spatter rate ensures board cosmetics and user comfort are maintained.All this translates to a safe and environmentally compliant product that is operator friendly while maintaining high levels of productivity.

BBIEN LF-05 Sn64Bi35Ag1 made 0.5mm~2.0mm no clean soldering wire is recommended for use in any hand soldering application where high flux activity is desired.

It was developed to provide superior wetting performance for hand soldering in the electronics industry.The chemistry is based on some of the same principles that have been safely used for years in mildly activated rosin fluxes.The use of LF-05 bismuth solder wire results in an extremely clear post-soldering residue without cleaning.The unique chemistry in Sn64Bi35Ag1 is also designed to reduce spattering common to most core fluxes.Sn64Bi35Ag1 can be used for both lead bearing and tin bismuth low temperature soldering.


The BBIEN LF-05 Sn64Bi35Ag1 Pb free low temperature soldering wire is suitable for both manual and machine soldering of electrical and electronic components.The flux residues do not need to be removed.

Sn64Bi35Ag1 lead free no clean solder wire is specifies compliance to the IPC J-STD-004B ROL0 standard.It is ideal for electronic assemblies used in tomotive,Consumer Electronics,Computer and peripherals,Mobile devices and all types of Au household appliance applications.As well as apply to High-precision medical instrumentation.

Feature of Sn64Bi35Ag1 soldering wire

Low temperature anti-oxygen satisfactory soldering joint and favorable fluidity.Solder joints are filled,and firm.Both RA and RMA are made in complicance with IPC J-STD-006 and JIS Z3283 class AA standards.All these solder flux can be dissolved in solvent,featuring a little smoke and very few splatters.

Application notes

Use a soldering iron tip size and form to suit the operation:

small tips for soldering large components may prevent the formation of a joint or slow the process down.

Select a solder wire diameter to suit both the soldering iron tip and the parts/components to be soldered.

Soldering iron systems should provide sufficient heat to satisfy the requirements of the points above.A typical solder tip temperature would be between 138°C and 179°C above the liquidus temperature of the Sn-Bi-Ag alloy.

The ideal temperature to use is depending on how thermally demanding the assembly is.Cored solder wires can be provided in different grades of alloy so always ensures that you have selected the right gradefor the application.


BBIEN LF-05 Sn64Bi35Ag1 lead free solder wire’s soldering residues are non-corrosive,non-conductive and do not require removal in most applications.IPA will not clean the residues off the surface of the circuit board after the soldering process.

Storage and Shelf Life

The shelf life of NNIEN LF-05 Sn64Bi35Ag1 no clean solder wire is based on the chemistry of the flux core and the protective alloy covering of the wire.

When stored in a dry,non-corrosive environment between 10°C-40°C(50-104°F),the shelf life of wire may be nearly

Flux-cored solder wires alloys have a 1-3 year warranty from the date of manufacture.

Over time,the surface of wire may lose its shine and appear a dull shade of gray.This is a surface phenomenon and is not detrimental to product functionality.
