Sn99Ag0.3Cu0.7 High Melting Bar Solder
BBIEN LF-04 Sn99Ag0.3Cu0.7 high quality melting solder barSn99Ag0.3Cu0.7 solder bar descriptionBBIEN LF-04 SACX0307(Sn99Ag0.3Cu0.7) is a antioxidant lead-free alloy wave soldering bar that contains 99 % tin, 0.3% silver, and 0.7% copper. This alloy falls under the JEIDA recommendation for lead-free soldering. When used in wave soldering, BBIEN’s SACX0307 bar solder offers far superior fluidity as compared to other alloys and makes of bar, resulting in excellent flow. BBIEN’s SACX0307 tin-silver-copper alloy bar solder also produces less dross than other bar solder, wets well, provides superior joint strength, and offers superior copper dissolution rates. BBIEN’s SACX0307 bar solder is alloyed in the proprietary Electropure™ method that results in a low drossing, high wetting solder. The Electropure process reduces suspended oxides in the solder, thus reducing drossing, improving flow and reducing bridging during soldering. SACX0307 may be used with most existing equipment, processes, coatings, and flux chemistries.Technical DatasheetSpecificationsProduct TypeSolder bar Sn99Ag0.3Cu0.7BrandBBIENMaterialTin-Silver-Copper alloyCompositionSn,Ag,CuMelt point227 degree CelsiusUsingMatch with solder flux for wave solderingApplicationMetal soldering,electronicsDensity (g/m^3)7.35Bar/Stick size32*2.0*45pxWeightAppox 0.9kg/pcTypeHigh temperature solder barPlace of originMade in ChinaCertificateSGSKeywordTin silver copper lead free oxidation resistance solder barSACX0307 lead free solder barSolder bar SACX0307BBIEN is one of suppliers who have this difficult technical to make this kind of high temperature BBIEN is one of suppliers who have this difficult technical to make this kind of high temperature oxidation resistance solder bar.We also got the approval of RoHS and REACH for lead free solder bar ISO9001 system of management and testing system reach the international standard.Temperature Requirements: Wave soldering pot temperature of 265° -270°C (509° -518°F).

In order to optimize yourprocess, it is recommended to perform a design experiment, optimizing the most important variables (i.e.amount of flux applied, conveyor speed, topside preheat temperature, solder pot temperature and boardorientation, etc…).Recommended AC Tion Levels for Wave Solder Impurities Alloy Coposition: Sn: Balance Ag: 0.3 ± 0.2 Cu: 0.7 ± 0.1Impurity ContentsPlease find below a list of recommended action levels for wave solder bath impurities. For information of specific action plans to bring your solder bath back to an acceptable condition please contact BBIEN sales office.ElementACTION Levels %NotesSnBALNo Action level.Pb0.10RoHS Directive 2011/65/EU states a maximum Lead content of 0.1%.As0.03Levels greater than 0.03% can cause de-wetting.Cu1.0SACX 0307 is tolerant to copper levels up to 1.0%, SACX 0300 copper free should be added to maintain copper levels. Levels above 1.0% may cause more bridging.Bi0.20Lead Free alloys are tolerant to Bi up to 1.0%, however if levels above0.20% are detected this indicates some contamination issues that should be investigated.Zn0.003Levels greater than 0.003% may cause increased bridging and icicling, as well as, increased drossing rates in the solder bath.Fe0.02Greater than 0.02% Iron can be an indicator of pot erosion and may cause gritty joints and the formation of FeSn2 IMC needles that can cause bridging.Ag1.0Silver levels of 4% are used in some SAC alloys, however if the levels inSACX 0307 rise above 1.0% then some investigations should be held toestablish the cause.Sb0.20Lead Free alloys are tolerant to Sb up to 1.0%, however if levels above0.20% are detected this indicates some contamination issues that should be investigated.Ni0.05Levels greater than 0.05% may start to slow wetting and may reduce hole fill.Evaluate soldering performance if levels exceed 0.05%.
