Liquid Solder Flux

Liquid solder flux BBIEN LF-01 liquid wave solder flux is activated rosin liquid flux is a homogeneous solution of high quality purified high grade rosin in a specially blended alcohol vehicle into which a very small amount of an extremely effective activating agent has been incorpo-rated.BBIEN LF-01 flux is classified as Type ROL1 flux under IPC ANSI/J-STD-004 Joint Industry Standard. BBIEN LF-01 is a high quality lead free solder flux,also a low solids,weak-halide,no-clean flux that is designed for wave solder,selective solder and touch up processes,it approved as type RMA and has proven to be nearly as active in fluxing ability as highly activated rosin fluxes,but the flux and its residue are considerably less conductive.The low conductivity results from a minimum of ionic activating agent as shown by the very high water extract resistivity.The rosin residue is non-corrosive,non-conductive,and moisture and fungus resistant.The dry rosin residue actually insulates the surface from atmospheric corrosion.General packing is 16kg/20l per drum

BBIEN LF-01 Liquid solder flux

Introduction for BBIEN liquid LF flux

BBIEN LF-01 flux is a weak-halide activated foam flux conforming to with non-corrosive residues .BBIEN LF-01 liquid solder flux is a ready to use foam flux for wave soldering machines and has been specially formulated for applications in the electronic industry for soldering of printed circuits. The residues on printed circuit boards are dry and fast to handle immediately after the soldering process. During circuit testing test needles do not get clogged, so that cleaning of the boards is not required.

Classification for solder flux

BBI-LF-01 no clean soldering flux belongs to 2-Propanol types of flux,which is using for wave soldering using flux. Special design to meet the wettability for wave soldering. Bright spot welding. Flux in the appropriate internal activity solid content and its mechanism ensure the little residue after welding circuit,and board surface drying, cleaning. In un-specificness conditions,it exempt cleaning process,then save the operating costs of manufacture. It has with excellent welding performance. For wave soldering can reduce bridge or other defects.

FEATURES

Exhibits exceptional electrical reliability for a low-solids wave soldering flux. Complies with IPC-J-STD-004 SIR, Bellcore SIR, Bellcore ECM, JIS ECM, and JIS SIR.

Thermally stable activators provide minimized solder bridging in a low-solids, no-clean flux for wave

soldering and Selective Soldering in lead-free and tin-lead applications.

Reduces the surface tension between solder mask and solder to resist solder ball formation.

Very low level of non-tacky residue to reduce interference with pin testing. Exhibits no visible residues.

• Low solid content

• Welding spot surface brightness

• High wettability

• Non-cirrisuveness

• No residue generates after welding and no need to clean

• According with ANSI/J-STD-004

• High surface insulation resistance, and not obviously decreased

Application

During the soldering process most of the flux is rinsed off the PCBs. Should cleaning be desired, the remaining flux residues can be easily removed using an alkaline cleaner. All known cleaning processes, such as by brushing, ultrasonic, steam etc. are appropriate. Evaporation of solvent can change the composition. Evaporation causes an increase of solid content and therefore density increases.

HANDLING

• Sealing save time for 1 year, do not cryopreservation this product.

• Away from fire, avoiding direct sunlight or hyperpyrexia.

• Without stirring before using.

• Do not use residual flux and flux, keep container sealing hybrid packaging.

• Before using the flux which be long-term storage, proportion shall be measured,and adding thinners to adjust to the normal proportion.

Note:BBIEN LF-01 soldering flux is apply for wave soldering technique. The above parameters for reference only,don't guarantee to obtain the best welding effect. As the different conditions of the equipment, components, PCB aspects of user, user had better use experimental design method to obtain the optimum parameters.

Main technical data of flux

PROCESS CONTROL

In the process of using soldering flux control is very important,it can guarantee the composition of flux not change. Wave soldering process accurate control of flux can not only ensure the same welding effect, but also residuel at least after welding . Then to eliminate scratching of the test of solder probe.

Health & Safety:

This product, during handling or use, may be hazardous to health or the environment. Read the Material safety Data Sheet and warning label before using this product.

Consult the SDS for all safety information. The most recent version of the SDS is available from BBIEN. Inhalation of the flux solvent and volatilized activator fumes, which are generated at soldering temperatures, may cause headaches, dizziness and nausea. Suitable fume extraction equipment should be used to remove the flux from the work area. An exhaust at the exit end of the wave solder machine may also be needed to completely capture the fumes. Observe precautions during handling and use.

Suitable protective clothing should be worn to prevent the material from coming in contact with skin and eyes.

BBIEN LF-01liquid flux contains a highly flammable solvent with a flash point of 53°F (12°C). The flux must not be used near open flames or near non-flameproof electrical equipment.

FLUX APPLICATION 

BBIEN LF-01 wave liquid solder flux is formulated to be applied by spray methods. A uniform coating of flux is essential to successful soldering. When spray fluxing, the uniformity of the coating can be visually checked by running a piece of pH sensitive paper matching the footprint of the assembly over the spray fluxer.
