Lead free silver soldering bar SAC305

SAC305 lead free wave silver soldering bar BBIEN LF-03 Sn96.5Ag3Cu0.5 and is lead-free alloys suitable for use as a replacement for Sn63Pb37 alloy.The SAC305 Sn-Ag-Cu series Pb-free wave silver solder bar/stick variants is used to stabilize/reduce the copper content in the wave solder bar;this requirement will depend on process conditions.As with all our metals bar solder,BBIEN’S proprietary alloying process is used to remove certain impurities,particularly oxides.

Product Details

BBIEN LF-03 SAC305 lead free wave silver soldering bar

Product’s Introduction forSAC305

BBIEN LF-03 SAC305(Sn96.5Ag3.0Cu0.5)is a lead-free solder according to ISO

9001:2008 which can replace eutectic or almost eutectic tin/lead or tin/lead/silver

alloys.BBIEN LF-01 SAC305 alloy solder bar is manufactured from pure metals and has

been developed to eliminate the use of tin/lead alloys in all existing production processes

in electronics manufacturing and guarantees a lead-free wave soldering process.

Products Characteristics Advantage

Good wetting characteristics

Melting range of 217 to 222°C

Longer service life due to reduced copper content

Lower cost than eutectic SnAgCu alloy due to 0.8%lower silver content

Yield–Best in class yield,out performs all Sn/Cu based materials

Wetting speed–fast wetting,in back to back tests 0.65s compared to 1.00s,for Sn/Cu based materials

Dross generation–Low dross generation delivered by Vaculoy alloy conditioning

Excellent solderability due to fast wetting speed

Very good drainage,has lower levels of bridging compared to Sn/Cu alloys

Delivers excellent performance across a wide range of Flux technologies.

The proprietary Vaculoy process is a highly effective method for removing included

oxides from solder.This is extremely important because included oxides generate

excessive drossing and increase the viscosity of the solder.Solder with higher viscosity

can result in increased soldering defects

Application Notes:

On changing to lead-free production the temperature profile and process conditions for this alloy-like for any other lead free alloys,too-must be adjusted.The resulting solder joints will have comparable or even better characteristics than solder joints,which were made with Sn/Pb solders.During the use in a solder bath the copper content increases with the consequence,that the liquidus of the alloy is rising,causing soldering defects Therefore a regular analytical control of the solder composition is necessary in order to maintain the copper content below 1%.

The use of BBIEN LF-03 SAC305 as wave solder requires a solder bath temperature of approx.260 to 265°C.The use of inert gas means a significant extension of the process window.The wetting of the solder is made easier and on exit from the wave,no excess solder remains attached to the components.BBIEN LF-03 SAC305 lead free silver wave solder bar can also be used in selective soldering systems.

RECOMMENDED CONDITIONS OF USE

Wave Soldering:The low copper content is advantageous for wave soldering because longer operating times of the solder bath can be achieved.By dissolving of copper from the PCB the copper content increases. Using ECOLOY®TSC305 means that it takes longer until the critical limit of 1.0%is reached. The use of BBIEN LF-03 SAC305 silver solder bar as wave solder requires a bath temperature of approx.265°C.Depending on PCB type and types of components, the optimum of the process conditions must be determined. The usage of inert gas brings a considerable extension of the process window.The wetting of the solder will be easier, and there will be no excessive solder on the PCBs when leaving the wave.Moreover the formation of dross will be minimised considerably.

Wave Soldering Fluxes:In general,all conventional fluxes like BBIEN LF-01 flux is suitable for the lead free soldering process.The flux solid content should be high enough.Due to the increased preheating and wave temperature a better activity respectively temperature stability is an enormous advantage.

Rework und Hand Soldering:Adjusted flux content assures a proper soldering for rework and repair.The temperature profiles,which were made for tin/lead/silver alloys,must be adjusted due to the higher melting point(+34°C compared with Sn/Pb eutectic).In case that components or PCBs have a lead containing coating,the solidus of the new alloy will be reduced to the solidus of the eutectic Sn/Pb/Ag alloy.
