SAC305 Lead Free Wave Silver Soldering Bar
Product DetailsBBIEN LF-03 SAC305 lead free wave silver soldering barProduct’s Introduction forSAC305BBIEN LF-03 SAC305(Sn96.5Ag3.0Cu0.5)is a lead-free solder according to ISO9001:2008 which can replace eutectic or almost eutectic tin/lead or tin/lead/silveralloys.BBIEN LF-01 SAC305 alloy solder bar is manufactured from pure metals and hasbeen developed to eliminate the use of tin/lead alloys in all existing production processesin electronics manufacturing and guarantees a lead-free wave soldering process.Products Characteristics AdvantageGood wetting characteristicsMelting range of 217 to 222°CLonger service life due to reduced copper contentLower cost than eutectic SnAgCu alloy due to 0.8%lower silver contentYield–Best in class yield,out performs all Sn/Cu based materialsWetting speed–fast wetting,in back to back tests 0.65s compared to 1.00s,for Sn/Cu based materialsDross generation–Low dross generation delivered by Vaculoy alloy conditioningExcellent solderability due to fast wetting speedVery good drainage,has lower levels of bridging compared to Sn/Cu alloysDelivers excellent performance across a wide range of Flux technologies.The proprietary Vaculoy process is a highly effective method for removing includedoxides from solder.This is extremely important because included oxides generateexcessive drossing and increase the viscosity of the solder.Solder with higher viscositycan result in increased soldering defectsApplication 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.PackingSpecificationSn99-Ag3.0-Cu0.5 bar soldersAppearanceLucent,no dirt on surfaceSizeLength×wideness×Thinckness×Weight(L×W×T×W):800px×45px×37.5px×0.7kg/pc 20kg/cartonUsageBBIEN LF-03 SAC305(Sn96.5Ag3.0Cu0.5)Pb-free wave soldering bar is suitable for wave soldering and surface mount applications for electronic assemblers interested in implementing a lead-free process.A solder pot temperature of 255-265°C(491-509°F)is recommended.For suitable wave solder fluxes,please see our selector guide.Lead free Reclaim services including dedicated lead free containers are also available.Please consult BBIEN sales office.AVAILABILITYBBIEN lead free soldering bar available in 0.9kg bars,feeder Ingots and autofeed wire.Most products are shipped strapped and palletized or packed in corrugated cardboard box with no remarkable damages in appearanceRECOMMENDED CONDITIONS OF USEWave 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.Technical DatasheetBBIEN LF-03 SAC305 lead free wave silver soldering barTachnical SpecificationBBIEN LF-03 SAC305 silver solder bar complies with all requirements of RoHS Directive (Article 4.1 of the European Directive 2011/65/EU). Alloy specification for maximum Lead (Pb) Content = 0.07%. SAC alloy is also available in Ultra Low Lead (ULL) version which contains a maximum of 0.05% Pb. All alloy properties remain the same for SAC ULL.CharacteristicSAC 305Melting Point217-219ºC(423-426ºF)Density37.37 g/cmTCE (Range 20-100ºC)micrometers / M / ºC21.9Specific HeatCapacity0.232 J/g
